Risk Adjustment
Risk Adjustment is the method developed and used by the Department of Health and Human Services (HHS) to predict health costs of members enrolling in Affordable Care Act (ACA) or Medicare Advantage (MA) plans. Risk Adjustment prevents health plans from only attracting and enrolling healthy members, known as adverse selection. Effective Risk Adjustment programs ensures members are receiving quality care and enable health plans to offer more comprehensive and affordable benefits to members.
Arkansas Health and Wellness is required by law to report complete and accurate diagnostic information on enrollees. This information is gathered from claims data and information obtained from medical record reviews and audits.
We encourage all providers to take every face-to-face encounter as an opportunity to provide comprehensive care and document chronic and co-existing conditions, active status conditions, and pertinent past conditions using the applicable ICD-10 code and supporting the condition with proper documentation in the medical record.
Arkansas Health and Wellness is required to validate member diagnosis annually through a Risk Adjustment Data Validation (RADV) audit. Health plans also engage in chart review projects to ensure member diagnoses are being reported accurately.
Arkansas Health and Wellness engages providers through various incentive programs that reward providers for risk adjustment gap closure.
Cardiac Arrhythmias[1]
An arrhythmia is an abnormal heart rhythm. Arrhythmias occur when the electrical impulses that coordinate your heartbeats don’t work properly, causing your heart to beat too fast, too slow, or irregularly.
RISK FACTORS:
- Hypertension
- Heart attack
- Abnormal heart valve
- Coronary artery disease
- Emphysema/lung disease
- Stress
- Congenital defects
- Viral infections
- Metabolic imbalance
- Thyroid disorder
- Stimulants
- Smoking
SYMPTOMS:
- Palpitations
- Chest pain
- Weakness/fatigue
- Confusion
- Blood pressure change
- Shortness of breath
- Lightheadedness
- No symptoms
Paroxysmal Tachycardia
Tachycardia is a fast heart rate; in adults, a rate greater than 100 beats per minute is considered tachycardia. Paroxysmal tachycardia is characterized by periods of rapid heartbeats that start and stop abruptly.
There are 2 types of paroxysmal tachycardia:
- Supraventricular Tachycardia occurs when the rapid heart rate originates in the heart’s upper chambers (the atria).
- Ventricular Tachycardia involves a rapid heart rate originating in the lower chambers of the heart (the ventricles). Ventricular tachycardia lasting longer that a few seconds can lead to ventricular fibrillation, the most serious and life-threatening cardiac rhythm disturbance.
Atrial Fibrillation and Flutter
Atrial fibrillation and flutter are arrhythmias involving the atria. They may come and go or be sustained. Risk of stroke or heart failure is increased if either atrial fibrillation or atrial flutter is not controlled or persists for more than a couple of days.
- Atrial fibrillation is a rapid, irregular heart rate caused by chaotic electrical impulses in the atria. These cause rapid, uncoordinated, weak contractions of the atria and blood is not moved from the atria into the ventricles effectively. Atrial fibrillation is the most common type of arrhythmia.
- Atrial flutter is characterized by a rapid but regular heartbeat that causes the atria to beat too fast, producing atrial muscle contractions that are faster than and out of sync with the ventricles.
Sick Sinus Syndrome (SSS)
SSS, also known as "Sinoatrial node dysfunction" or "Tachycardia-Bradycardia syndrome," is the name given to a group of arrhythmias in which the sinus node, the heart’s natural pacemaker, doesn’t send impulses properly. As a result, the heart might beat too fast, too slow, or it might speed up and slow down intermittently.
Treatment options depend largely upon the severity of a patient’s symptoms. Many with SSS initially experience few, if any, symptoms. At this stage, treatment usually consists of regular checkups and monitoring. Once a patient’s symptoms become more problematic, further treatment is pursued.
Many with SSS eventually need a permanent artificial pacemaker to monitor and regulate the heart’s rhythm and send electrical signals to stimulate the heart when it’s beating too slowly.
A pacemaker controls but does not cure SSS, therefore, it is a reportable chronic condition.[2]
Patients who have a rapid heart rate as part of their SSS may need additional treatments after pacemaker placement to control fast rhythms.
Treatment Options
- Anti-arrhythmic drugs
- Heart-rate control drugs
- Anticoagulant therapy
- Electrical cardio conversion
- Anti-bradycardia pacing
- Coronary artery bypass
- Pulmonary vein isolation
- Catheter ablation
- Maze procedure
- Valve surgery
There are many cardiac devices designed to help control irregular heartbeats, such as pacemakers, implantable cardioverter-defibrillators (ICDs), and loop recorders. These are often surgically implanted in the chest or abdominal wall, just below the collarbone.
CARDIAC DEVICES
Coding and Documentation[3]
When documenting cardiac arrhythmias, include the following:
- Location — atrial, ventricular, supraventricular, etc.
- Rhythm name — flutter, fibrillation, etc.
- Acuity — paroxysmal, persistent, longstanding, chronic, etc.
- Cause — hyperkalemia, hypertension, etc.
ANTICOAGULANT THERAPY
- Documentation must state the relationship between anticoagulation therapy and cardia arrhythmias. It cannot be assumed since anticoagulants are used to manage other conditions.
- Even when the conditions are linked, document the type, status and severity of the arrhythmia. Anticoagulant therapy is also used to prevent blood clots in patients with a history of cardiac arrhythmias. - Z79.01: Long term (current) use of anticoagulants.
HISTORY OF
- Document “history of,” along with a specification that the condition is no longer current in the final assessment.
- If the condition is currently active and under management do not specify as “history of,” even if stable.
- There is not a specific code for personal history of cardiac arrhythmia. Use Z86.79: Personal history of other diseases of the circulatory system.
PRESENCE OF CARDIAC DEVICE
- Z95.0 Presence of a cardiac pacemaker
- Z95.810 Presence of automatic (implantable) cardiac defibrillator
- Z95.811 Presence of heart assist device
- Z95.818 Presence of other cardiac implants and grafts

Chronic Kidney Disease[1]
The clinical criteria for chronic kidney disease (CKD) is either kidney damage or a decreased glomerular filtration rate (GFR) of less than 60 for at least three months. When the reduction of functional renal mass reaches a certain point, irreversible sclerosis leads to a progressive decline in the GFR.
ICD-10-CM[2] classifies CKD by the severity level of decreased kidney function.
STAGE | SEVERITY | GFR | ICD-10 |
---|---|---|---|
Stage I | Mild kidney damage (normal function) | ≥ 90 | N18.1 |
Stage 2 | Mildly decreased renal function | 60-89 | N18.2 |
Stage 3 | Unspecified severity | Unspecified | N18.30 |
Stage 3a | Mild to Moderate | 45-59 | N18.31 |
Stage 3b | Moderate to Severe | 30-44 | N18.32 |
Stage 4 | Severe | 15-29 | N18.4 |
Stage 5 | Kidney Failure | < 15 | N18.5 |
ESRD | Requires dialysis/transplant | < 15 | N18.6 |
CKD, Unsp. | Renal disease, renal insufficiency, or renal failure NOS. | N/A | N18.9 |
The GFR value can be used as supporting evidence for renal failure, renal insufficiency, or other renal diseases documented by the provider. It cannot be interpreted to stage CKD or other renal conditions.
Signs and Symptoms
Patients with CKD stages 1-3 are generally asymptomatic. Typically, it is not until stages 4 or 5 that endocrine/ metabolic derangements or disturbances in water or electrolyte balance become clinically manifested.
When the disease progresses, symptoms presented are:
- Edema of feet and ankles
- Need to urinate more often, especially at night
- Nausea
- Blood or protein in urine
- Chest pain
- Twitching and cramps in the muscles
- Shortness of breath
- Erectile dysfunction, amenorrhea, or decreased libido
- Fatigue
- Platelet dysfunction with tendency to bleed
- Loss of appetite
- High blood pressure (hypertension)
Coding and Documentation[3]
Acute vs. Chronic
Acute kidney failure is not an acute exacerbation of chronic kidney failure. They are two separate and distinct conditions. The causes, symptoms, treatments, and outcomes of acute and chronic are different.
- Acute renal failure has an abrupt onset and is potentially reversible.
- Chronic kidney failure progresses slowly over time and can lead to permanent kidney failure.
If both acute and chronic kidney failure are clearly documented, code both N179 (AKI) and N18.[4]
End-Stage Renal Disease
End-stage renal disease (ESRD) is when the kidneys permanently fail to work. ESRD requires renal dialysis or kidney transplant.
- Code N18.6: Assigned when ESRD is documented by provider.
- Code Z99.2: Dependence on renal dialysis when documentation supports the presence of an arteriovenous shunt/fistula for dialysis.
- Code Z91.15: Patient's noncompliance with renal dialysis when explicitly documented.
“With”
Patients with CKD may also suffer from other serious conditions, most commonly diabetes mellitus and hypertension. The sequencing of the CKD code in relationship to codes for other contributing conditions is based on the conventions in the Tabular List.
Diabetes with Kidney Complications
Relationship between diabetes and CKD or ESRD (N18.1 - N18.6) is assumed when both conditions are found anywhere in the note as long as there is no conflicting documentation
- Use an additional code to identify stage of chronic kidney disease (N18.1-N18.6)
- The ICD-10 “With” guideline only applies to CKD
- Unspecified (N18.9): When CKD unspecified has been assessed during the encounter.
Hypertensive Chronic Kidney Disease
Hypertension and CKD have an assumed relationship unless documentation specifies CKD is caused by a condition other than hypertension.
- Assign code from category I12.
- Use an additional code to identify stage of chronic kidney disease with I12.0 (N18.1-N18.4, N18.9) or I12.9 (N18.5-N18.6).
Hyperparathyroidism
Hyperparathyroidism is a pathologic manifestation of CKD.
- Documentation MUST link the complication and the conditions to assign code N25.81: Hyperparathyroidism of renal origin.
- Do not assume causal relationship between these two conditions.

ALL21-AR-H-085 Updated October 22, 2021
Chronic obstructive pulmonary disease (COPD) is a progressive chronic respiratory disease that causes blocked airways and breathing-related problems. COPD can be caused by long-term exposure to harmful particles or gases that irritate the lungs such as tobacco smoke and exposure to air pollution.[1]
Types of COPD
Chronic bronchitis - hypersecretion of mucus with chronic productive cough lasting more than three months in two consecutive years[2]
- Simple – non obstructive; smokers cough (J41.0)
- Mucopurulent – production of sputum containing mucus and pus (J41.1)
- Mixed – chronic simple and mucopurulent bronchitis (J41.8)
- Chronic bronchitis, NOS (J42)
Emphysema – enlarged or over inflated air space in the lung due to damaged alveoli (air sacs) or alveolar wall resulting in breathing difficulty and increased risk of respiratory infections.
- Unilateral pulmonary emphysema – MacLeod’s syndrome (J43.0)
- Panlobular – Affecting lower lobes (J43.1)
- Centrilobular – Affecting upper lobes (J43.2)
- Other and Unspecified (J43.8, J43.9)
Chronic obstructive pulmonary disease – Chronic bronchitis and emphysema causing irreversible airflow obstruction
- With (acute) respiratory infection (J44.0)
- With (acute) exacerbation (J44.1)
- COPD, unspecified (J44.9)
Stages of COPD[3]:
Stage | Pulmonary Function | Symptoms |
---|---|---|
I Mild | 80% or greater | Persistent, dry cough; shortness of breath during exertion |
II Moderate | 79% - 50% | Persistent cough with excess mucus, shortness of breath during mild activity, wheezing, fatigue, and sleep disturbance |
III Severe | 49% - 30% | Frequent respiratory infections, edema, cyanosis, tightness in chest, trouble breathing while performing basic tasks, and difficulty taking a deep breath |
IV End-stage | 29% or less | Constant wheezing and shortness of breath, inability to inhale deeply increased heart rate and blood pressure, and loss of appetite and weight |
COPD Treatment and Management
There is no cure for COPD, but early intervention can slow the disease progression and reduce the risk of complications. Treatment for COPD can include:
- Antibiotics — fights bacterial infection
- Bronchodilators — opens airways
- Bullectomy — removal of air space from collapsed air sacs
- Corticosteroids — reduces inflammation
- Lung transplant — replaces diseased lung with a healthy one
- Lung volume reduction — removes diseased lung tissue
- Oxygen therapy — reduces shortness of breath
- Pulmonary rehabilitation — includes disease management, exercise, and counseling
- Smoking cessation — slows progression
- Vaccines — lowers risk of flu or pneumonia
Asthma
Asthma is a chronic lung disease causing inflammation and constriction of the airways that affects the ability to breathe. Asthma triggers may be different for each person and can change over time. Different triggers cause different types of asthma.[4]
- Allergic — Dust mites, mold, pollen, pets, household pests, etc.
- Non-allergic — Cold air, medications, household chemicals, air pollution, tobacco smoke, infection, etc.
- Exertional — Induced by exercise or physical activity.
- Occupational — Caused by breathing chemicals or industrial dust particles at work.
Asthma is classified by frequency and severity of symptoms, as well as complications of the disease: (J45.-).
- Mild, moderate, severe
- Intermittent, persistent
- Uncomplicated, with acute exacerbation, with status asthmaticus
Diagnostic Testing[5]
Document diagnostic test results and any clinical findings that support the diagnosis, along with disease status and treatment plan.
- Bronchoscopy — procedure using a small camera on the end of a long flexible tube, or scope, to look at air passages
- Bronchoprovocation — tests pulmonary response or reaction to the drug methacholine.
- Chest x-ray — imaging test to look at the structures and organs of the chest
- Computed tomography (CT) scan — computerized digital scan that creates two-dimensional, cross-sectional images
- Endobronchial ultrasound (EBUS) — bronchoscopy performed using scope with an ultrasound probe attached
- Fractional exhaled nitric oxide (FeNO) test — measures levels of nitric oxide exhaled from a breath
- Lung biopsy — procedure to collect a tissue sample used in disease diagnosis
- Peak Expiratory Flow (PEF) — measures speed of air blown out of the lungs using maximum effort
- Pulse oximeter (Pulse Ox) — measures the saturation of oxygen carried in your red blood cells
- Spirometry — measures volume capacity and the force of air expelled from the lungs
A diagnosis is not supported by the simple reference of a diagnostic study. The provider must interpret the results and include the clinical significance in the medical record.
Coding and Documentation
ICD-10 code assignment depends on documentation details that should include:
- Specific diagnosis
- Severity, frequency, or complication
- Condition status and controlling agents
- Causal relationships
- Coexisting and/or underlying conditions
Refer to the tabular list for guidance on diagnosis inclusions, exclusions and additional coding notes.
Use Additional Codes to identify:
- Exposure to environmental tobacco smoke (Z57.31, Z77.22)
- Tobacco use (Z72.0), tobacco dependence (F17.-), or history of tobacco dependence (Z87.891)
- Dependence on supplemental oxygen (Z99.81); use of long-term supplemental oxygen regardless of the duration each day[6]
- Dependence on respirator [ventilator] (Z99.11); use of respirator or ventilator for life support[7]
- Long-term (current) use of inhaled or systemic steroids (Z79.5)
- Other diseases of the pleura (J90-J94)
- Intraoperative and post-procedural complications and disorders of respiratory system (J95)
- Other diseases of the respiratory system (J96-J99)

Coagulation Defects and Other Specified Hematological Disorders[1]
Coagulation (also known as clotting) is the process by which blood changes from a liquid to a gel, forming a blood clot. Clotting results in hemostasis, the cessation of blood loss from a damaged vessel. It is achieved through a series of interactions between platelets, blood vessel walls, and adhesive blood proteins known as clotting factors.
Coagulation disorders involve disruption of the clotting process and may result in:
- Hemorrhage: Too little clotting that causes an increased risk of bleeding. Examples include:
- Von Willebrand disease
- Primary thrombophilia
- Activated protein C resistance
- Hemophilia
- Hereditary factor XI deficiency
- Evans syndrome
- Thrombocytopenia
- Allergic purpura
- Thrombosis: Too much clotting that causes blood clots to obstruct blood flow. Examples include:
- Factor V Leiden mutation
- Antithrombin III (ATIII) deficiency
- Primary thrombocytosis
- Antiphospholipid antibody syndrome
- Prothrombin (PT) gene mutation
- Protein C or protein S deficiency
- Lupus anticoagulant syndrome
Signs, Symptoms, and Treatment of Hemorrhagic Disorders
Signs & Symptoms
- Blood in the urine or stool
- Sudden pain, swelling, and warmth in the joints or muscles
- Nosebleeds that seem to have no cause
- Repeated vomiting
- A painful headache that will not go away
- Extreme fatigue
- Bruising easily and excessively, or petechiae
- An injury that will not stop bleeding
- Prolonged bleeding from cuts, surgery, or dental work
- Vision problems, such as double vision
- An enlarged spleen
Treatment
- RICE — Rest, ice, compression, and elevation
- Infusion
- Transfusion
- Desmopressin (Willebrand factor synthetic hormone)
- Discontinuation of aspirin and other NSAIDs
Hemophilia[2]
Hemophilia is a hereditary blood disease characterized by greatly prolonged coagulation time. The blood fails to clot, and abnormal bleeding occurs.
Hemophilia is a sex-linked hereditary trait transmitted by normal heterozygous females who carry the recessive gene occurring almost exclusively in males.
- Factor VIII deficiency (classic hemophilia, hemophilia A) associated with recurrent, spontaneous, and traumatic hemarthrosis
- Factor IX deficiency (hemophilia B, Christmas disease, plasma thromboplastin component)
- Von Willebrand disease
- Type 1 - Partial quantitative deficiency of von Willebrand factor; Type 1C von Willebrand disease
- Type 2 subtypes include qualitative defects of von Willebrand factor
- type 2A - with decreased platelet adhesion and selective deficiency of high-molecular-weight multimers
- type 2B - with high-molecular-weight von Willebrand factor loss; with hyper-adhesive forms; with increased affinity for platelet glycoprotein lb
- type 2M - with defective platelet adhesion with a normal size distribution of von Willebrand factor multimers
- type 2N - with defective von Willebrand factor to factor VIII binding; with markedly decreased affinity for factor VIII
- Type 3 - (Near) complete absence of von Willebrand factor; Total quantitative deficiency of von Willebrand factor
- Acquired von Willebrand syndrome
- Other – platelet-type; pseudo-von Willebrand disease
Acquired hemophilia, developing after birth, is a rare condition caused by the development of antibodies (immune system proteins) directed against the body’s own VIII or IX blood clotting factors.
- Non-genetic disorder affecting both males and females
- Can be related to other conditions (e.g. pregnancy, cancer, certain medications)
Frequency and severity of hemorrhagic activity induced by hemophilia are related to the amount of coagulation factor in the blood.
Mild Hemophilia | Moderate Hemophilia | Severe Hemophilia |
---|---|---|
5% to 40% of normal coagulation factor | 1% to 5% of coagulation factor activity | less than 1% of coagulation factor activity |
complications only after having undergone surgery or major physical trauma | some spontaneous hemorrhage but normally exhibit bleeding provoked by trauma | spontaneous hemarthrosis and bleeding |
Treatment depends on the severity of the disease and may include the administration of blood clotting factors such as Factor VIII, Factor IX, Factor VIIa and, Anti-inhibitors to control the bleeding.
Thrombocytopenia
Thrombocytopenia occurs when the platelet count falls lower than 150,000 platelets per μl of blood. Circulating platelets are reduced by one or more of the following:
- Trapping of platelets in spleen caused various other disorders
- Decreased platelet production can be caused by leukemia, chemotherapy, heavy alcohol consumption certain anemias, and viral infections (Hep B, HIV)
- Increased breakdown of platelets
Treatment
- Identify and treat underlying cause
- Splendectomy
- Corticosteroids/immunosuppressants
- Blood or platelet transfusions
Primary Thrombocytosis
Primary Thrombocytosis, also known as Primary Thrombocythemia (ET), is an uncommon disorder in which the body produces too many platelets.
Signs, Symptoms, and Complications
- Fatigue
- Lightheadedness
- Vision changes
- Increased risk of blood clots, myelogenous leukemia (AML), and myelfibrosis
Treatment
- Low dose aspirin
- Anagrelide
- Hydroxyurea
- Interferon alfa or pegylated interferon alpha 2a
Coagulopathy[3]
Coagulopathy is impaired clot formation or any derangement of hemostasis resulting in either excessive bleeding or clotting. Document coagulopathy when appropriate to reflect the seriousness of the condition. Specify the underlying etiology of coagulopathy to support the diagnosis.
- When patient is maintained on anti-platelets and/or an anti-coagulant, document coagulopathy due to anti-coagulation or anti-platelets use, if linked to bleeding.
- If coagulopathy is documented due to abnormal ROTEM (rotational thromboelastometry), additional clinical relevance will help validate the diagnosis:
- Need
- Type
- Screen in anticipation of blood products transfusion (ffp)
Coding & Documentation
Quality patient care relies on complete documentation.
- Accurately capture the patient’s health status.
- Note condition details, including status, complications, and comorbidities.
- Report the diagnosis to the highest specificity found in the documentation.
All providers must fully understand and follow all existing laws, regulations, and rules for hemophilia clotting factors and must properly submit valid claims for them. Relevant CMS manual instructions and policies may be found in the Internet-Only Manuals (IOMs) published on the CMS website.

Updated on March 1, 2022
Condition status Z codes are informative and distinct from “history of” codes. “History of” codes indicate a past condition has been resolved and is not present. Condition status codes indicate that a patient is either a carrier of a disease or has the sequela or residual of a past disease or condition. The status can affect the course of treatment and its outcome, but they are commonly overlooked. [1]
Amputation Status — Category Z89
Codes in Category Z89 describe traumatic or post-procedural absence of a limb, when there are neither complications of the amputation nor treatment directed toward the site. Documentation should include anatomical location and laterality.
Artificial Opening Status — Category Z93
Codes in Category Z93 describe functional artificial opening status. Artificial openings can be permanent or temporary depending on circumstances of creation. These codes are appropriate when no treatment is directed at the site. Documentation should include date of initial procedure and/or reversal, if applicable.
Organ Transplant Status — Category Z94
Category Z94 codes identify post-transplant status when there are no complications of the transplanted organ. A code from this category is appropriate as an additional code when treatment of a condition does not affect the function of the transplanted organ.
Supplemental Oxygen or Respirator Dependence – Category Z99
Category Z99 codes identify supplemental oxygen or ventilator dependence status when there is no complication or malfunction of the equipment on which the patient is dependent.[2] Dependence status can be for a short or long period of time in the hospital, another medical setting, or at home. Dependence on supplemental oxygen status is appropriate for any patient using long-term supplemental oxygen, regardless of the duration of use each day. Use dependence on respirator [ventilator] status codes when respiratory device or equipment is for life sustaining support.
Renal Dialysis Status
ICD-10-CM includes codes for dependence on renal dialysis and noncompliance with renal dialysis. These codes are appropriate when the presence of AV shunt for renal dialysis is indicated.
Lifelong Chronic Conditions[3]
Lifelong chronic conditions often require ongoing medical attention and the associated diagnoses are typically unresolved once diagnosed. It is appropriate to report these conditions, even when stable, if documented in any part of the medical record at the time of the encounter.

- When presence affects medical decision making or a pertinent factor of overall health.
- During a wellness or physical exam, at least once per calendar year for as long as they exist.

[4] ICD-10 Diagnosis
Heart Failure is a chronic, progressive condition in which the heart is unable to pump enough blood to meet the body's needs for blood and oxygen. Heart failure is usually caused by another condition that either damaged the heart or caused it to work too hard.
Risk Factors:
- Hypertension
- Diabetes
- Endocarditis
- Coronary artery disease
- Congenital heart disease
- Cardiomyopathy
- Obesity
- Sleep apnea
- Severe lung disease
Signs and Symptoms:
- Edema in the feet, ankles and legs
- Fatigue, weakness, or lightheadedness
- Irregular or fast heartbeat
- Dyspnea, orthopnea, or persistent coughing
- Confusion, impaired thinking, or decreased ability to concentrate
Types of Heart Failure
Heart failure can affect either the heart’s left or right side, or both sides, and it can be acute, chronic, or acute-on-chronic.
- Left-sided heart failure – or left ventricular (LV) heart failure – Failure of the left ventricle, the main pumping chamber of the heart, to pump blood out to the body effectively. Accumulation of excess fluid behind the left ventricle causes dyspnea, orthopnea, paroxysmal nocturnal dyspnea, and/or acute pulmonary edema.
There are two different types of left-sided heart failure which call for different treatment approaches:- Systolic heart failure – Heart failure with reduced ejection fraction (HFrEF) – the left ventricle loses its ability to contract normally. The heart can’t pump with enough force to push enough blood into circulation.
- Diastolic heart failure - Heart failure with preserved ejection fraction (HFpEF) – the left ventricle loses its ability to relax normally because the muscle has become stiff. The heart can’t fill properly with blood during the resting period between each beat.
- Right-sided heart failure, or right ventricular (RV) heart failure – Failure of the right ventricle to move blood returning from systemic circulation into the lungs. Blood backs up in the body’s veins, causing systemic venous congestion (distended neck veins), pitting edema of the lower extremities or other dependent portions of the body, enlarged tender liver, and/or ascites.
- Chronic heart failure develops slowly, and the onset of symptoms may be gradual. Treatment is aimed at managing the underlying cause, minimizing symptoms, and preventing the heart failure from becoming worse.
- Acute heart failure develops suddenly, and symptoms are initially severe which may be experienced until the underlying condition is identified and treated. This can happen with:
- Severe anemia
- Hyperthyroidism
- Pulmonary embolism
- Arrhythmia
- Severe infections or allergic reaction
- Acute on chronic heart failure occurs when there is an acute decompensation of chronic heart failure.
Coding and Documentation
When documenting heart failure, include the following:
- Type — systolic, diastolic, etc.
- Acuity — acute, chronic, etc.
- Disease status — stable, improved, etc.
- Treatment plan — medicines, lifestyle changes, etc.
Code all documented conditions present at the time of the encounter that require or affect patient care, treatment, or management. This includes stable chronic conditions and comorbidities. Include the ICD-10 coded to the highest specificity on the claim.
“Exacerbated” or “Decompensated”
Coding guidelines advise that “exacerbation” and “decompensation” indicate an acute flare-up of a chronic condition. When systolic or diastolic heart failure is described in these terms, the appropriate code indicating acute on chronic heart failure should be assigned.
Congestive heart failure
The term congestive heart failure refers to the back up of fluid into the lungs and tissues. Assign code I50.9, heart failure NOS for a diagnosis of unspecified congestive heart failure.
“With”
When documentation links either systolic or diastolic dysfunction with heart failure, report as systolic/diastolic heart failure. Link CHF to other associated conditions unless specifically documented as “unrelated.”

- Chronic kidney disease (CKD)
ALL21-AR-H-084 Updated on October 20, 2021
Dementia relates to changes in cognitive functioning — thinking, remembering, reasoning, and behavior. Alzheimer’s disease is the most common type of dementia. While developing dementia becomes more common as people grow older, it is not a normal part of aging. Dementia can be found in other diseases and conditions, such as:
- Degenerative neurological diseases
- Vascular disorders
- Traumatic brain injuries
- Infections of the central nervous system
- Long-time alcohol or drug use
Types of Dementia[1]
Different types of dementia are associated with different damage to a particular region of the brain.
Alzheimer’s disease — This is the most common form of dementia. Tau and beta-amyloid proteins accumulate and become toxic, destroying the brain’s balance.
Vascular dementia — This type of dementia is caused by strokes or other issues with blood flow to the brain.
Lewy body dementia (LBD) — LBD is associated with abnormal deposits of a protein called alpha-synuclein.
Parkinson’s disease — Nerve cells in and of the brain that control movement become impaired and/or die. These brain cells contain Lewy bodies.
Frontotemporal dementia — This type of dementia causes damage and degeneration specific to behavior and language.
Mixed dementia — Mixed dementia is a condition in which more than one type of dementia is present at the same time.
Risk factors
- Aging — Most dementia cases affect individuals ages 65 and older.
- Family history — Those who have parents or siblings with dementia are at a higher risk for developing the condition.
- Poor heart health — High blood pressure, high cholesterol, and smoking cigarettes can all increase the risk of developing dementia.
Treatment[2]
Treatment for dementia will often focus on symptom management, particularly agitation and other emotional concerns. Symptoms may improve with treatment, but many diseases that cause dementia have no cure.
Palliative care
- Support and counseling
Medication
- Cholinesterase inhibitors slow the breakdown of a brain chemical involved in memory and judgment.
- NMDA (N-methyl-D-aspartate) inhibitors help control a different brain chemical needed for learning and memory
- Antidepressants can improve low mood and irritabilit
- Anxiolytics can ease anxiety or restlessness
- Antipsychotics can help control feelings and behaviors such as aggression, agitation, delusions, or hallucination.
Coding & Documentation
Best Practices
To ensure dementia is accurately reported, documentation should include the following:
- Dementia type (e.g., vascular, dementia with Lewy bodies, frontotemporal).
- Underlying physiological condition(s) (e.g., Alzheimer’s, Parkinson’s).
- Severity (mild, moderate, severe).
- Presence of behavioral disturbance, psychotic disturbance, mood disturbance, and/or anxiety.
- Wandering.
- Comorbidities such as hypertension or diabetes and relationship to dementia, if applicable.
Coding Chronic Conditions
Chronic conditions that require ongoing care should be documented in the patient record and reported for the visit each time they require or affect patient treatment or management. Dementia places great strain on the body and would likely affect medical decision-making for all but the most minor of encounters.
Monitor, Evaluate, Assess, Treat (MEAT)
Any disease or disorder reported for a patient should be supported by documentation showing that the condition was monitored, evaluated, assessed, and treated (MEAT) during the patient encounter. For dementia, evidence of MEAT might include the follow
- Monitor - Monitor for signs and symptoms, or lack thereof, such as:
- Short-term memory loss.
- Wandering.
- Evaluate - Take note of physical findings, such as:
- Agitation.
- Ability to self-care (ADLs).
- Assess - Assess conclusions about the condition, such as:
- Disease control.
- Efficacy of treatment.
- Treat - Make important treatment decisions surrounding:
- Medication.
- Referrals to/notation of specialists, such as a neurologist or psychologist.
- - Provide patient/caregiver education regarding:
- Diet, exercise, and lifestyle changes.
- Support group information.
ICD-10-CM[3]
There are many codes added to ICD-10-CM effective October 1, 2022, that further classify the severity of dementia and the presence of behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety. Assign the ICD-10-CM code(s) that most clearly describe the patient’s condition, matching the diagnosis documented by the provider.[4]
Guidelines
Codes that have “in diseases classified elsewhere” in the title should never be the first listed or principal diagnosis. ICD-10-CM has instructional notes indicating the proper sequence order of codes. Code the underlying condition first, followed by the manifestation when applicable. See “code first,” “use additional code,” and “code also” guidelines.
Category F01 — Vascular dementia
Assign codes from Category F01 when an infarction of the brain due to vascular disease, including hypertensive cerebrovascular disease, is present as the cause of dementia.
Category F02 — Dementia in diseases classified elsewhere
Codes from category F02 are reported secondary to the code for the underlying condition. Tip: A code from subcategory F02 (dementia in other diseases classified elsewhere) should always be assigned with Alzheimer’s disease regardless of whether documentation states it.
Category F03 — Unspecified dementia
Use Category F03 codes when documentation does not further specify the type or cause of dementia. Tip: Report F03.90 and F05 if the patient has presenile dementia with delusional features and senile dementia with delirium.
Category F10 — Alcoholic dementia
There are codes in Category F10 used to indicate alcohol-induced persisting dementia. Tip: Documentation for alcohol-related disorders should specify the pattern of behavior as use, abuse, or dependence.

WLCR22-AR-H-136 Updated January 3, 2023
Occasionally, a reported diagnosis may be omitted from a claim due to errors or limitations of electronic claims submission. Improve the capture of risk adjustment conditions by entering the diagnosis codes on the claim correctly.
Diagnosis “pointers” connect the diagnosis made by the provider to each CPT® code billed on the claim. Only four (4) diagnosis pointers can be listed per CPT® code.
- Identify the 4 most important or serious diagnoses that the procedure is intended to treat.
- Enter the diagnosis pointers in order of severity.
Maximize reporting opportunities:
Avoid missing eligible risk adjustment conditions by thorough documentation and accurate diagnosis coding.
- Address all conditions present at the time of the encounter that require treatment or management.
- Report all chronic conditions that impact treatment or care, even if stable. This includes pertinent status codes.
- Explicitly state each diagnosis and provide documented evidence of support in the medical record.
- Capture all valid ICD-10 diagnosis codes in the appropriate order on the claim form.
Always follow the current ICD-10-CM Official Guidelines for Coding and Reporting[1] Refer to the Medicare Claims Processing Manual2 for additional information.

Health Insurance Claim Form (PDF) - Coming soon
Documentation Requirements[1]
Documentation must:
- Result from a face-to-face encounter with acceptable provider in an acceptable setting type.
- List the complete date of service (month/day/year).
- Contain at least two patient identifiers on EACH page of every document (Name, DOB, MRN).
- Include legible handwritten signature with credentials or proper EMR electronic authentication.
- Explicitly state the diagnosis and clearly document supporting evidence of an active/current condition.
Condition Assessment
Assess the status of conditions for which interventions are recommended or underway. Code all documented conditions that coexist at the time of the encounter/visit and require or affect patient care treatment or management. This includes ongoing chronic conditions, even if stable.
Documentation from past dates of service may not be used to report codes for the current date of service.
Current/Active Diagnosis
MEAT and TAMPER are used as tools to help coders determine if a condition can be coded as current or active. At least one of the following elements must be present in at least one section of the medical record (Subjective, Objective, Assessment, Plan) to substantiate the presence of a condition:
- Monitor, Evaluate, Assess/Address, Treat
- Treat, Assess, Monitor/Medicate, Plan, Evaluate, Refer
"History Of"
Do not code conditions that have been treated or no longer exists. Documentation where the provider has used the term(s) “history of” will be coded using the appropriate diagnosis code for the historical condition. The condition should not be referenced as a “history of” if it is a chronic condition currently undergoing treatment.
Condition Lists
Conditions mentioned in Past Medical History or Active Problem List must be supported in another section of the medical record in order to verify the condition is active. The best practice is to include evidence of current review in the form of medication, referrals, order of lab tests, etc. in the assessment and plan.
Specificity
Document to the highest degree, and code to the highest specificity. The ICD-10 diagnosis code must match the wording used in documentation. Explicitly state the diagnosis and follow the official conventions and guidelines for coding and reporting.
Consistency
Be clear and consistent throughout the medical record when documenting details of a condition. A diagnosis cannot be validated when the record contains conflicting information.
Reporting
When a condition is assessed and documented in a face-to-face encounter, include the corresponding ICD-10 diagnosis code on the claim form submitted to the health plan.
Telehealth[2],[3]
Telemedicine Visits provided via synchronous audio and video technology meet the face-to-face requirement for risk adjustment. Documentation must include that the visit was performed using interactive audio/video with real-time, two-way communications. Virtual Check-Ins, E-Visits, and Telephone Visits are not acceptable.
Resources
[1] Documentation Requirements (PDF)
[2] Medicare has expanded telehealth coverage and eased current restrictions for the duration of the COVID-19 crisis. During this time, telehealth services that meet the face-to-face documentation requirements can be used for risk adjustment.

[4] ICD-10-CM Official Guidelines for Coding and Reporting (PDF)
The Official ICD-10-CM Guidelines[4] are the authoritative source for diagnosis coding and documentation. Please refer to the current year’s guidelines for detailed instructions. These guidelines and other information about risk adjustment can be found on CMS’s website.
Follow the guidelines and assign the appropriate combination codes when reporting hypertension and another condition.[1]
The relationship between hypertension, heart disease, and chronic kidney disease is assumed when conditions are found together, unless explicitly documented unrelated.
Applies to conditions found in I50.-, I51.4-I51.7, I51.89, I51.9Category I11 — Hypertensive Heart Disease
- Code separately only if heart disease stated "Not due to hypertension."
- Use additional code from category I50, Heart Failure, if applicable
Category I12 — Hypertensive Chronic Kidney Disease (CKD)
- Code separately only if documentation specifies cause other than hypertension.
- Use additional code to identify the stage of the CKD.
- Also code dialysis status, if applicable.
Category I13 — Hypertensive Heart and Chronic Kidney Disease
- Do NOT separately code for hypertension, heart disease, and chronic kidney disease or assign with codes from categories I11 or I12
- Use additional code for heart conditions I50.-, I51.4-I51.7, I51.89, I51.9
- Also code the appropriate stage of CKD (N18.- ) and dialysis, if applicable
For conditions not found under the term “with”, the relationship between hypertension and another condition must be specifically documented in order to code them as related.
Category I15 — Secondary Hypertension
Secondary hypertension is due to an underlying condition.
- Assign the code for the underlying condition and a code from category I15.
Category I16 — Hypertensive Crisis
- Use a code from category I16 when hypertensive urgency, hypertensive emergency, or unspecified hypertensive crisis is documented.
- Code also any identified hypertensive disease (I10- I15)
Category I27 — Pulmonary Hypertension
- Pulmonary hypertension is classified to category I27, Other pulmonary heart diseases.
- Code also any associated conditions or adverse effects of drugs or toxins.
Hypertensive Cerebrovascular Disease
- Assign code from Categories I60-I69, followed by the appropriate hypertension code (I10-I15)
Hypertensive Retinopathy
- Code H35.0 — Background retinopathy and retinal vascular changes with the applicable code from Category I10-I15.
Transient Hypertension
When a hypertension diagnosis has not been established, assign one of the following codes:
- R03.0 — Elevated blood pressure reading without hypertension.
- O13.- — Gestational (pregnancy-induced) hypertension without significant proteinuria.
- O14.- — Pre-eclampsia, for transient hypertension of pregnancy.

ALL21-AR-H-091 Updated on October 21, 2021
Ischemic Heart Disease[1]
Atherosclerosis
Atherosclerosis is the buildup of fatty deposits, or plaque, within the coronary arteries. Plaque buildup causes narrowed or blocked blood vessels, which can lead to more serious conditions such as acute coronary syndrome and myocardial infarction.
Coronary atherosclerosis is categorized by the type of vessel in which it occurs:
- Native coronary artery
- Coronary artery bypass graft (CABG)
- Autologous or non-autologous artery or vein
- Other CABG
- Artery of transplanted heart
Atherosclerosis is also known as atherosclerotic heart disease (ASHD), coronary artery disease (CAD), or atherosclerotic cardiovascular disease (ASCVD).
RISK FACTORS:
- Diabetes
- Hypertension
- Poor diet
- Smoking
- High cholesterol
- Obesity
- Lack of exercise
- Age
- Gender
- Family history
- Poor dental health
- Stress
When documenting atherosclerosis, include the following:
- Location — Coronary artery involvement, vessel type
- Symptoms — Angina, shortness of breath, etc.
- Comorbid conditions — Hypertension, tobacco use, etc.
Angina
Angina is chest pain or discomfort caused when the heart muscle does not get enough oxygen-rich blood. It is usually a symptom of an underlying heart condition such as coronary artery atherosclerosis.
SIGNS and SYMPTOMS:
- Chest pain or discomfort, pressure, squeezing, or fullness in the center of the chest.
- Radiating pain in the arms, neck, jaw, shoulder, or back.
- Nausea, fatigue, shortness of breath, sweating, or dizziness.
TYPES and SEVERITY:
- Refractory — chronic angina that does not respond to medical treatment or intervention[2]
- Stable — Pain that is usually caused by exertion or excitement and stops when at rest or with medication.
- Unstable — Pain changes in frequency, duration and intensity. Does not go away with rest or medicine.
- Variant — Coronary vasospasm that occurs most often while at rest. Associated with transient ST-segment elevation.
When documenting angina, include the following:
- Type — Stable, unstable, etc.
- Cause — Presumed to be ASHD, note if there is another cause
- Timing/precipitating factors — Exercise, emotional stress, etc.
- Relieving factors — Medications, rest, etc.
Not all chest pain is angina. “Angina” must be explicitly stated. Stable or asymptomatic angina that is controlled by a medication is an active condition and should be assessed, documented, and reported at least once per year. Use “history of” when the condition has resolved, and treatment is no longer needed.
Heart Disease Prevention and Management
Heart Disease Prevention and Management
Lifestyle changes: | Medications: | Procedures |
---|---|---|
Low-fat and low-sodium diet | Statins | Stents |
Quit smoking | Calcium channel blocker | Angioplasty |
Limit alcohol intake | Antianginals | Bypass |
Moderate exercise, 30min/day | Beta blockers | Implant device |
Myocardial Infarction (MI)
Myocardial infarction, known as a heart attack, is the permanent, gross necrosis of the myocardium (heart muscle tissue death). An electrocardiogram (ECG) reading will differentiate an ST elevation myocardial infarction (STEMI), or classic heart attack, from a non-ST myocardial infarction (NSTEMI), sometimes called a mild heart attack.
A heart attack occurs when a blocked artery interrupts blood flow to a section of the heart. If the blockage is not treated quickly, that part of the heart begins to die. Symptoms may be immediate and intense but typically start slowy and persist for hours, days or weeks before a heart attack. Report in acute/post-acute care setting or following transfer to another acute setting.
CLASSIFICATON:[3]
- Type 1 — Spontaneous
- Type 2 — Ischemic
- Type 3 — Unknown
- Type 4 — (3 subtypes, a-c)
- a — Due to percutaneous procedure
- b — Due to stent thrombosis
- c — Due to restenosis
- Type 5 — Due to CABG
- Myocardial Injury — non-ischemic; acute or chronic
Cardiac arrest is triggered by an irregular heartbeat (arrhythmia) affecting the heart’s ability to pump blood to other organs. Cardiac arrest occurs suddenly, often without warning. It is reversible if treated within the first few minutes but is fatal without quick intervention.
ICD-10-CM
Category I20 — Angina Pectoris & Category I25 — Chronic ischemic heart disease
ICD-10-CM presumes a causal relationship between ASHD and angina when no other cause has been identified for the angina. These same conditions are coded separately when the provider has specifically documented a different cause for angina.[4]
- I25.2, old MI — Healed myocardial infarction or MI older than four weeks (28 days).
Category I21 — Acute MI
- Type 1 — Initial myocardial infarction from onset up to four weeks (28 days) old.
- Unspecified AMI or unspecified type is assigned I21.9.
- Types 3-5 are coded I21.A9.
- Use code I5A for non-traumatic myocardial injury (acute, chronic, or non-ischemic)
Category I22 — Subsequent MI
- Occurrence of an acute MI within the four-week time frame of the initial acute MI.
- Code with a category I21 code.
Category I23 — Current complication following MI
- Must be coded with a Category I21 or Category I22 code.
- "Post-infarction angina” must be stated to assign (I23.7) as a current complication.
Category I24 — Acute ischemic heart disease
- Acute blood clots in the coronary arteries without myocardial infarction.
- Acute coronary syndrome (ACS).[5]

Major Depressive Disorder[1]
Major Depressive Disorder, also known as clinical depression, is a common mood disorder characterized by a depressive episode having five or more symptoms causing significant distress or impairment (not caused by substance abuse or other conditions) lasting two or more weeks. At least one of the five symptoms must be depressed mood or loss of interest.
Symptoms of Depression:
- Depressed mood
- Feelings of worthlessness or guilt
- Fatigue or low energy
- Insomnia or hypersomnia
- Significant change in weight or appetite
- Loss of interest or pleasure in most or all activities
- Psychomotor retardation or agitation
- Recurrent thoughts of death or suicidal ideation
- Poor concentration
Depression screening tools, such as the PHQ-9,[2] are used to identify the presence and level of severity.
PHQ-9 Depression Scoring
SCORE | SEVERITY | PROPOSED TREATMENT |
---|---|---|
0-4 | None-Minimal | Education on available supportive services |
5-9 | Mild | Watchful waiting: Repeat PHQ-9 at follow-up visit |
10-14 | Moderate | Treatment Plan: Consider counseling and/or medication, follow-up visits |
15-19 | Moderately Severe | Active Treatment: Pharmacotherapy and/or psychotherapy, follow-up visits |
20-27 | Severe | Immediate initiation of pharmacotherapy, expedited referral to mental health specialist for psychotherapy and/or collaborative management |
Bipolar Disorder[3]
Bipolar disorder, sometimes called manic-depressive disorder, causes extreme shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks. People with bipolar disorder experience periods of intense emotion, changes in sleep patterns and activity levels, and unusual behaviors. These distinct periods are called “mood episodes.” A provider would have to determine whether they may be the result of another cause (such as low thyroid, or mood symptoms caused by drug or alcohol abuse).
Symptoms of Mania:
- Talking more/faster than usual
- Inflated self-esteem (grandiose delusions)
- Extremely high energy and irritability
- More easily distracted
- Increased high-risk/reckless behavior
- Decreased need to sleep
Symptoms of Hypomania:
- Increased restlessness and irritability
- Extremely low energy and fatigue
- Decreased self-esteem
- Difficulty concentrating or making decisions
- Lasting sad, anxious, or empty mood
- Disturbance in sleep/wake cycle
Symptom Profile[4]
Bipolar Type 1:
- Marked by manic episodes
- Hospitalization due to mania likely
- Psychosis may occur during manic episodes
Bipolar Type 2:
- Marked by hypomanic episodes
- Hospitalization due to hypomania less likely
- Psychosis unlikely to occur during hypomania
SCHIZOPHRENIA
This disorder affects the way a person thinks, feels and acts. It makes it difficult to differentiate what is real and what is not. Symptoms vary by severity and type. All symptoms may or may not be present in individuals with the condition.[5]
Symptoms of Schizophrenia:
- Hallucinations
- Lack of focus
- Extreme, disorganized thoughts
- Impaired memory
- Delusions
- Difficulty completing tasks
- Movement disorders
- Unmodulated speech
Coding & Documentation
Major depression and bipolar disorders are classified by their features (type, severity, and presence of psychosis).[2] Symptoms can manifest differently from person to person. A patient’s complete overall health status requires accurate, detailed documentation of the provider’s assessment.[6]
Condition Status
- ACTIVE/CURRENT — Provider assessment confirms the condition exists and the diagnosis is documented in the medical record. A patient can have a current diagnosis without being actively involved in treatment.
- “HISTORY OF” — Patient has previously been diagnosed, the condition has completely resolved, and treatment is no longer needed. Past medical history (PMH)
Avoid using non-specific terms and unspecified codes when details of the condition are known.

Neoplasms and Cancer[1]
A neoplasm is an abnormal growth or mass of cells called a tumor. Tumor growth, or behavior, can be benign (non-cancerous) or malignant (cancerous). Benign tumors grow in one place and do not spread to other body parts. Malignant tumors grow, spread, and invade other body parts (metastasis).
Types of Cancer
Cancer can start almost anywhere in the human body. Primary cancer refers to the origin of a malignant neoplasm. Metastatic cancer, or secondary cancer, is the formation of a new tumor in a secondary site from the metastasis of the primary cancer.
Cancer is usually classified by the location it started (i.e., lung cancer, colon cancer, breast cancer, etc.) or the type of cell where it was formed.
- Carcinoma – Epithelial cells; cells covering inside or outside surfaces
- Sarcoma — Bone and soft tissue; includes muscle, fat, blood and lymph vessels, tendons and ligaments,
- Leukemia — Bone marrow
- Lymphoma — Lymphocytes (T cells & B cells), white blood cells
- Myeloma — Plasma cells
- Melanoma — Melanocytes, melanin producing cells (pigmented tissue such as skin or eyes)
Detection and Staging
Cancer staging is based on the extent of the tumor. Laboratory studies of blood, urine, and stool to detect abnormalities that may indicate cancer. Imaging tests such as X-rays, CT, MRI, ultrasound, and fiber-optic endoscopy help determine the suspected cancer’s location and size. A biopsy can confirm the diagnosis of most cancers, and other tests can provide specific information about the cancer.
The stage of cancer indicates information about the location, cell type, size, and grade, and if it has spread to a different part of the body. A cancer is always referred to by the stage it was given at diagnosis regardless of progression or regression.
Carcinoma in situ | Stage I, II, and III | Stage IV |
---|---|---|
Abnormal cells present but confined to the point of origin without invasion of the surrounding normal tissue. | Cancer is present. The higher the number, the larger the cancer tumor, and the more it has spread into nearby tissues. | Cancer has grown very extensive and/or has spread to distant parts of the body. |
Cancer Treatments
Treatment depends on the cancer type, and how advanced it is. Malignant tissue can be removed with surgical excision or treated using targeted therapy, precision medicine, or stem cell transplant.
Targeted Therapy — Use of drugs to attack specific types of cancer cells with less harm to normal cells.
Precision Medicine — Use of genetic and environmental proteins to treat the cancer.
Stem Cell Transplant — Cancerous bone marrow is replaced with healthy bone marrow from a donor.
Coding & Documentation[2]
Clearly document all know details of the patient’s condition. This should include:
- Behavior — Malignant, Benign
- Location — Site specific (cell type, anatomical location, laterality)
- Type — Primary, Secondary (include cancer stage)
- Status — Active, In remission, "History of"
Tips:
For active cancers, document the current treatment. If patient has refused treatment or is under watchful waiting, document the reason and disease progress.
If the patient receives adjuvant therapy, indicate if it is for treatment or prophylactic purposes.
Also report the type of cancer treatment used:
- Radiation Therapy (Z51.0)
- Chemotherapy (Z51.11)
- Immunotherapy (Z51.12)
- Hormone Therapy (Z79.890)
ICD-10-CM Guidelines[3]
When assigning the diagnosis for neoplasms and cancer, refer to the Neoplasm Table found in the alphabetic index first, unless the histological term is documented (ex. Adenoma). The terms “lump” or “mass” should never be indexed to the neoplasm table. The index directs a coder to see “mass” instead.
- Neoplasm that overlaps two or more contiguous sites should be coded (overlapping lesion) unless specifically classified elsewhere.
- When treatment is directed at the malignancy, make the malignancy the principal diagnosis.
- If the encounter is solely for the administration of chemotherapy, immunotherapy, or radiation therapy, assign a code from category Z51- first.
- When treatment is directed toward a secondary site only, the secondary neoplasm is designated as the principal diagnosis.
Active vs. Historical
Documentation should clearly indicate and provide support for the current condition.
Do not code “history of” when cancer is currently active or assign a code for active cancer if the disease has been treated and no longer exists.
Report a code for active cancer when documentation supports:
- Current treatment or patient’s refusal of treatment.
- Further treatment is directed towards site of excised malignancy.
- Watchful waiting.
History of cancer should be reported as personal history of malignant neoplasm with the appropriate code from category Z85- when documentation supports:
- Malignancy has been removed, treatment was completed and/or patient is being monitored for a recurrence.
- There is no evidence of disease and no further treatment being directed towards site.
- Adjuvant therapy is for prophylactic purposes.
Leukemia, multiple myeloma and malignant plasma cell neoplasms, have codes indicating whether the cancer has achieved remission status, or is in remission.
- Z85.6 Personal history of leukemia is only used when the physician documents that the patient has been completely cured

BMI and Weight Class
Body mass index (BMI) is the ratio between an individual’s weight and height. This formula is used to find BMI using pounds and inches: [2]
BMI = Weight (lb)/[Height (in)]2 x 703.
The BMI value typically corresponds with the amount of fat on an individual’s body and is used to screen for health risks associated with obesity.
Adult Weight Class (Applicable to individuals 20 years of age or older)
- Underweight: BMI less than 18.5
- Healthy Weight: BMI 18.5-24
- Overweight: BMI 25-29
- Obese: BMI 30 or higher
Obesity & Morbid Obesity
Obesity is further classified by severity.[3], [4]
Class 1: (High Risk) | Class 2: (Very High Risk) | Class 3: (Extreme Risk) |
---|---|---|
BMI 30-34 | BMI 35-39 | BMI 40+ |
Morbid obesity is defined as:
- BMI of 40 or greater
- BMI of 35 or greater and one or more co-morbid condition
- Being 100 pounds or more above ideal body weight
Risk Factors
Individuals with a high BMI have an increased risk of other chronic conditions. The higher the BMI the greater the chance of having serious complications,1 including but not limited to:
- Cancer
- Diabetes
- Emotional/Social issues
- Heart Disease
- High Blood Pressure
- High Cholesterol
- Mobility Problems
- Mortality
- Osteoarthritis
- Respiratory Disorders
- Sleep Apnea
- Stroke
However, obesity cannot be assumed from a BMI value. The calculation does not account for muscle mass, bone density, body composition, or ethnic and gender differences.
- Patients with a large waist circumference or excess body fat can be obese even if they have healthy BMI.
- Healthy patients with more lean muscle mass may have a BMI that falls into the obese range.
- Multiple patients can have the same BMI value without having the same weight related diagnosis.
Coding and Documentation[5]
The medical record must include the patient’s weight and the calculated BMI as well as the date of the exam. BMI can be documented by any clinician, including:
- Physician/other qualified practitioner
- Nutritionist
- Nurse
- Emergency Medical Technician
A diagnosis associated with BMI (i.e., overweight, obese, morbidly obese, etc.) must be explicitly documented by the treating physician or other qualified provider involved in the patient’s care.
Individuals who are overweight, obese, or morbidly obese are at an increased risk for certain medical conditions when compared to persons of normal weight. These conditions are always clinically significant and reportable when documented by the provider.[6]
Documentation should state the clinical significance of obesity to overall health including:
- Relationship to complications and/or comorbidities:
- Due to
- Complicated by
- Causal or contributing factors:
- Excess calories
- Drug induced
- Other disorder
Code all documented conditions that coexist at the time of the encounter/visit and require or affect patient care treatment or management.
ICD-10-CM codes for Body Mass Index (BMI) found in Category Z68[7] are to be reported only secondary to a related diagnosis.

Preventive visits are an important part of the process of keeping patients healthy. These visits improve quality of care and patient health outcomes by identifying patients who need disease management and intervention.
Initial Preventive Physical Exam
Medicare Advantage members are eligible for an Initial Preventive Physical Exam (IPPE) within the first 12 months of enrollment. The IPPE is also known as the Welcome to Medicare visit. The purpose of this visit is to review medical and social history and provide preventive services education.
Annual Wellness Visits
Beneficiaries are also eligible for an initial Annual Wellness Visit (AWV) after the first 12 months of enrollment, as well as a subsequent AWV once per calendar year. The AWV includes Personalized Prevention Plan Services (PPPS) and Health Risk Assessments (HRAs). It does not include a physical exam or other diagnostic procedures.
Annual Physical Exams
Routine Comprehensive Physical Exams (CPE) are performed without relationship to treatment or diagnosis for a specific illness, symptom, complaint, or injury. An annual CPE includes an appropriate history/exam with risk counseling and/or intervention. The extent and focus of the exam depend on the age and gender of the patient.

Tobacco smoking cessation counseling and substance abuse screening/intervention are included with CPE. Refer to the CPT code book for guidance on other services covered at the time of a preventive medicine exam.
Can Preventive Visits Be Performed on the Same Day as Another Visit?
A separately identifiable E/M service may be performed if prompted by symptoms or chronic conditions assessed during the AWV/CPE. Select the appropriate level of E/M services based on the following:
- The level of the medical decision making as defined for each service; or
- The total time for E/M services performed on the date of the encounter.
Append modifier -25 to the E/M service (99202–99215) when performed on the same day as an AWV (G0402, G0438–G0439) or CPE (99385–99387, 99395–99397).

Rheumatoid Arthritis and Other Inflammatory Connective Tissue Disorders [1], [2]
Rheumatoid arthritis (RA) is a systemic, autoimmune disease where the body’s immune system attacks its own joints, causing inflammation and joint damage. RA can occur at any age. Juvenile arthritis is a form of RA that develops in childhood that can carry into adulthood.
Signs and Symptoms
Symptoms of RA can come and go for some and be severe and continuous for others. The condition can lead to serious joint damage and disability in severe cases:
- Joint pain, stiffness, & swelling
- Warmth & redness of joints
- Nodules under the skin near joints
- Frequent fatigue
- Loss of appetite and weight loss
- Occasional fever
Clinical Criteria for RA Diagnosis:
- Inflammatory arthritis of three or more joints
- Positive RF testing
- Elevated levels of CRP or ESR
- Symptoms greater than six weeks
- Other similar diseases have been ruled out
- Rheumatology consultation
Diagnostic Tests:
- Rheumatoid factor test (RF)
- Anti-citrullinated peptide antibody test (ACPA)
- C-reactive protein test (CRP)
- Erythrocyte sedimentation rate (ESR)
- X-ray, MRI, and ultrasound
Diagnostic tests can provide support for a specific diagnosis. Test results cannot be used to assume a diagnosis more specific than the provider documents in the medical record.
Manifestations & Complications
RA is commonly known as a joint disease but it can also involve multiple organ systems.
Heart:
- Accelerated atherosclerosis
- Pericarditis
Nerves:
- Cervical myelopathy
- Neuropathy
Eyes
Episcleritis/scleritis Keratoconjunctivitis sicca peripheral ulcerative keratitis
Lungs:
- Caplan syndrome
- Interstitial lung disease
- Pleural effusion
- Pulmonary nodules
Blood:
- Amyloidosis
- Felty’s syndrome
Skin:
- Rheumatoid nodules
- Vasculitis
Increased risk of complications can arise as a result of the disease or the treatment of the disease such as depression, infection, or malignancy.
Treatment
The treatment of RA should begin as soon as the diagnosis has been made, and symptoms will need to be frequently monitored in order to minimize joint pain and swelling, prevent deformity, control manifestations, and maintain quality of life.
Treatments may include DMARDS, NSAIDS, corticosteroids, dietary changes, and physical therapy or exercise training.
Coding & Documentation
A provider must actively consider chronic comorbidities and their effect in the medical decision-making process. This consideration to appropriate to document in the medical record and should be reported on claims.[3]
Documentation should include:
- Etiology[4]
- Onset, frequency, and severity of symptoms
- Joint(s) affected, progression, and any deformities, if applicable
- Test results used to confirm diagnosis
- Associated complications
- Treatment used to control symptoms and/or prevent joint damage
ICD-10-CM[5]
Category M05-M06, M08
Combination codes for Rheumatoid arthritis specify:
- Presence of rheumatoid factor
- Organ or system affected
- Site & laterality
Other Inflammatory Connective Tissue Disorders:[6]
- Auto inflammatory Syndromes (M04.-)
- Psoriatic arthritis (L04.5-)
- Reiter’s Disease (M02.3-)

Overview
Epilepsy is a disorder of the brain. People are diagnosed with epilepsy when they have had two or more seizures. There are many types of seizures, and a person with epilepsy can have more than one type of seizure. The signs of a seizure depend on the type of seizure. Sometimes it is hard to tell when a person is having a seizure. A person having a seizure may seem confused or look like they are staring at something that isn’t there. Other seizures can cause a person to fall, shake, and become unaware of what’s happening around them.
Types of Seizures[1]
Generalized seizures affect both sides of the brain. Characteristics of certain seizures are outlined below:
- Absence seizures (petit mal): staring and subtle body movements; occur in clusters and cause a brief loss of awareness; often occur in children
- Atonic seizures: loss of muscle control, sudden collapse or falling down
- Myoclonic seizures: sudden, brief jerks or twitches of the arms and legs
- Tonic seizures: intense stiffening and contraction of the muscles
- Clonic seizures: associated with repeated or rhythmic, jerking muscle movements; usually affect the neck, face, and arms
- Tonicclonic seizures (grand mal): comprise two stages — a tonic phase and a clonic phase; most dramatic type of epileptic seizure and can cause an abrupt loss of consciousness, body stiffening and shaking, and sometimes loss of bladder control or biting of the tongue
Focal seizures (partial seizures) are located in just one area of the brain.
- Simple focal seizures affect a small part of the brain. These seizures can cause twitching or a change in sensation, such as a strange taste or smell.
- Complex focal seizures can make a person with epilepsy feel confused or dazed. The person will be unable to respond to questions or direction for up to a few minutes.
- Secondary generalized seizures begin in one part of the brain, but then spread to both sides of the brain. In other words, the person first has a focal seizure, followed by a generalized seizure.
Causes[2]
Infancy
- Congenital brain defects
- Genetics
- Down syndrome
Throughout Life
- Autism
- Medical conditions
- Head injuries
- Brain tumors
Elderly
- Alzheimer’s disease
- Stroke
Symptoms
Because epilepsy is caused by abnormal activity in the brain, seizures can affect any process the brain coordinates. Seizure signs and symptoms may include:
- Temporary confusion
- A staring spell
- Uncontrollable jerking movements of the arms and legs
- Loss of consciousness or awareness
- Psychic symptoms such as fear, anxiety, or deja vu
Symptoms vary depending on the type of seizure. In most cases, a person with epilepsy will tend to have the same type of seizure each time, so the symptoms will be similar from episode to episode.
Treatment
- Medication
- Vagus nerve stimulator
- Surgery
- Dietary changes
Diagnosis
- Blood tests — help discount other reasons for seizures, like genetic conditions or infections
- Neuropsychological tests — test speech, thinking, and memory skills to see if those areas of the brain have been affected by seizures
- Electroencephalogram (EEG) — records electrical activity in the brain
- Computerized tomography (CT) scan, positron emission tomography (PET) scan, magnetic resonance imaging (MRI) — show any abnormalities in the brain structure
- Functional MRI (fMRI) — shows which part of the brain uses more oxygen when the person speaks, moves, or does certain tasks
- Magnetic resonance spectroscopy (MRS) — creates an image to help compare how different parts of the brain work
- Single-photon emission computerized tomography (SPECT) — helps identify where seizures start in the brain
Complications
- Difficulty in learning in kids
- Psychological issues
- Permanent brain damage
- Aspiration pneumonia
- Pregnancy complications
- Injuries
Coding & Documentation Best Practices
Monitor, Evaluate, Assess, Treat (MEAT)
Any disease or disorder reported for a patient should be supported by documentation showing that the condition was monitored, evaluated, assessed, or treated (MEAT) during the encounter. For seizures/epilepsy, evidence of MEAT might include the following documentation:
Monitoring
- Feelings of fear or anxiety
- Temporary confusion
Evaluation
- Jerky movements in arms and legs
- Loss of consciousness
Assessment
- Disease control
- Efficacy of treatment
Treatment
- Referrals to/notation of specialists involved in care, such as neurologists
- Order tests: EEG, MRI, CT
- Patient education, such as:
- Seizure characteristics
- Medication and diet
Current vs. Historical
Do not describe current seizure(s), seizure disorder, or epilepsy as “history of.” In diagnosis coding, the phrase “history of” means the condition is historical and no longer exists as a current problem. Do not document past seizure(s) or seizure disorder as current if the condition has resolved, has not recurred, and is no longer being treated.
ICD-10-CM Categories[3]
Category R56, convulsions not elsewhere classified
Seizures or convulsions that are not identified as epilepsy or as a seizure disorder classify to category R56.
Category G40, epilepsy and recurrent seizures
Conditions in category G40 represent specific and precise diagnoses rather than a sign or symptom of another ill-defined disease or condition.
- Fourth, fifth, and sixth characters are added to specify the particular type of epilepsy or recurrent seizures, whether the condition is intractable, and with or without status epilepticus.
Conditions that classify to the epilepsy and recurrent seizures category G40 are:
- Seizure disorder
- Epileptic seizure(s)
- Epileptic attack
- Fit (NOS)
- Epileptic convulsion(s)
- Epilepsy Post-traumatic seizures/post-traumatic epilepsy
Post-traumatic seizures (PTS) and post-traumatic epilepsy (PTE) are complications from traumatic brain injury (TBI). PTE refers to recurrent and unprovoked PTS that occur at least one week after TBI.
- Post-traumatic seizures code to R56.1, which excludes post-traumatic epilepsy (G40.---).

Sepsis, Severe Sepsis, and Septic Shock[1]
Sepsis is the immune systems extreme response to an infection. The chemical released into the bloodstream by the immune system attack the body instead of fighting the infection. Sepsis can quickly lead to tissue damage, organ failure and death. Early identification and treatment is critical.
- Septicemia or sepsis — Bacterial, viral or fungal infection in the bloodstream, also called blood poisoning
- Inflammatory Response Syndrome (SIRS) — Systemic inflammation due to a blood born infection or other non-infectious cause such as trauma or injury
- Severe Sepsis — Sepsis with systemic organ dysfunction, hypoperfusion (reduced blood flow) or hypotension (low blood pressure)
- Septic Shock — Severe sepsis with extreme, persistent hypotension and circulatory failure
Signs and Symptoms
Sepsis may cause any of the following:
- Rapid breathing and heart rate
- Extreme pain or discomfort
- Shortness of breath
- Fever, shivering, or feeling very cold
- Confusion or disorientation
- Clammy or sweaty skin
- Nausea and vomiting
- Blotchy, pale, or discolored skin
Coding and Documentation
There is no single diagnostic test or comprehensive clinical criteria for sepsis. The diagnosis requires clinical judgment of the provider based on evidence of infection and organ dysfunction.[1]
The level of detail in the documentation impacts coding and reporting accuracy:
- Identify the infectious agent or causal organism as well as the related infectious or non-infectious condition.
- Document the severity of the condition, including the organ(s) affected, with the nature and severity of dysfunction.
- Specially state the causal relationship (due to/cause of) between sepsis and:
- Other infectious conditions
- Non-infectious conditions
- Post-procedural infections
To determine the proper code sequencing.
- Clearly state the reason for the hospital admission or the primary diagnosis.
- Note whether sepsis is present on admission or if it developed after admission, if not the cause.
Sepsis would not typically be assigned in the outpatient setting due to the acute nature of the condition.

ICD-10-CM GUIDELINES[2]
Refer to ICD-10-CM Official Guidelines for Coding & Reporting and review conventions in the tabular list.
- First, code for the underlying systemic infection. Use A41.9 Sepsis, unspecified organism, when the infection is not identified.
- Then use the appropriate codes to identify severe sepsis and septic shock.
- Additional code(s) for the associated acute organ dysfunction are required.
- Never assign severe sepsis or septic shock as principal diagnosis.
- Do not code severe sepsis unless severe sepsis or associated acute organ dysfunction is documented.
- Negative labs do not rule out sepsis when there is clinical evidence of the condition.
- Query provider when:
- clinical evidence of sepsis is present with negative or inconclusive labs.
- “urosepsis” is documented.

What Are Social Determinants of Health?
Social determinants of health are the conditions in the environments where people are born, live, learn, work, play, and age. These social factors can create significant barriers for a person’s wellness and health.
Who Can Collect SDoH Data?
Any member of a person’s care team can collect SDoH data. This includes providers, social workers, case managers, patient navigators, and nurses.
Why Is it Important to Collect SDoH Data?
This data allows our organization to develop and execute a coordinated and evidence-based strategy to improve population health.
Risk Adjustment Documentation and Coding Best Practices
The ICD-10-CM codes included in categories Z55–Z65[1] and Z75[2] identify non-medical factors that may influence a patient’s health status, such as their socioeconomic situation, including education and literacy, employment, housing, lack of adequate food or water, or occupational exposure to risk factors like dust, radiation, or toxic agents.
When providing services to a member, if social determinants are observed, the appropriate ICD-10-CM code(s) should be submitted on a claim. Including SDoH ICD-10 Z codes on the claims you submit will help to better strategize and address the social needs of our members.
The table below shows supplemental diagnosis codes and should not be used as the admitting or principal diagnosis code(s) to indicate the medical reason for the visit. The codes listed here are not all inclusive.
Supplemental diagnosis codes
ICD-10-CM | Category Problems/Risks Factors | Example Screening Questions |

WLCR22-AR-H-106 Updated on November 10, 2022
A cerebrovascular accident (CVA), also known as a stroke, occurs when there is an interruption to blood flow that supplies oxygen to the brain.[1] There are two different types of strokes:
- Ischemic Stroke — Blockage of blood vessel in the brain due to a blood clot or stenosis.
- Hemorrhagic Stroke — Bleeding into the brain caused by a broken blood vessel.
A stroke is an emergent event that requires treatment in an acute care setting.[2]
Residual or late effects (sequelae) caused by a stroke may be present from the onset of a stroke or arise at ANY time after the onset of the stroke. Some conditions develop slowly and exist over extended periods. Others develop suddenly and last only a few days or weeks.
A transinet ischemic attack (TIA) is a temporary episode of neurologic dysfunction caused by ischemia without acute infarction. It is sometimes referred to as a mini stroke because the symptoms are similar to that of a stroke. The symptoms can resolve within minutes, or can last up to 24 hours.
Documentation
Detailed documentation is necessary for proper code selection:
- Specify the location or source of hemorrhage and its laterality.
- Specify the source of occlusion, and the vessel affected.
- If applicable, identify the specific neurologic or cognitive deficit, identify the affected extremity and laterality and whether it is the dominant or non-dominate side, and specify the type of event as the causing of the sequelae.
Key Terms:[3]
- Stenosis — narrowing
- Occlusion — complete or partial obstruction
- Thrombosis — stationary blood clot lodged in vessel
- Embolism — blood or other clot carried through vessel
- Meninges — protective membranes surrounding the cerebral cortex (brain)
- Dura matter (outer), Arachnoid (middle), Pia matter (inner)
- Epidural — between dura matter and skull
- Subdural — between dura matter and arachnoid
- Subarachnoid — between arachnoid and pia matter
- Precerebral arteries — vertebral, basilar, carotid
- Cerebral arteries — anterior, middle, and posterior
Coding
Assign the most specific code as appropriate according to documentation. More than one code may be assigned if specific code is available for separate locations. Watch for parenthetical notes found in the tabular list (e.g., excluded conditions, coding sequence, etc.).
Acute conditions must only be reported when present and actively being treated. Chronic conditions should be reported when treatment is required and/or affects care. Once a condition has resolved, it should no longer be reported as active.
ICD-10-CM Codes:[4]
- Category I60-I62: Non-traumatic cerebral hemorrhage
- Category I63: Cerebral Infarction
- Category I65-68: Other cerebrovascular disorders and diseases
- Category I69: Sequelae of cerebrovascular disease
Acute conditions found in Category I60-I67 are applicable to the initial event.
After discharge from acute care, the condition is classified by:
- Sequela (late effects) found in Category I69; or
- Personal history of CVA or TIA without residual deficits, Z86.73
- Transient cerebral ischemic attack, G45.9 should be reported at the time of initial diagnosis. Refer to personal history of TIA and CVA without residual deficits, Z86.73 for subsequent encounters
- See Category S06 for Intracranial hemorrhage due to accident or injury (traumatic)
- See Category I97 & G97 for guidance on intraoperative and postoperative events. Causal relationships must be clearly documented.
- Use Additional code to identify presence of:
- Alcohol abuse and dependence (F10.-)
- Exposure to environmental tobacco smoke (Z77.22)
- History of tobacco dependence (Z87.891)
- Hypertension (I10-I16 )
- Occupational exposure to environmental tobacco smoke (Z57.31)
- Tobacco dependence (F17.-)
- Tobacco use (Z72.0)
NOTE: The information listed here is not all inclusive and is to be used as a reference only. Please refer to applicable coding and documentation resources for the current year. [5]

[5] ICD-10
In the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the American Society of Addiction Medicine created a category called substance use disorders. This category combines the concepts of substance abuse and substance dependence into a single disorder measured on a continuum from mild to severe.
Diagnostic Criteria[1]
DSM-5 defines substance use disorder as a problematic pattern of substance use leading to clinically significant impairment or distress, as manifested by at least two of the following occurring in a 12-month period:
DSM-5 Criteria for Substance Use Disorders
- Substance is often taken in larger amounts or over a longer period of time than was intended
- Persistent desire or unsuccessful efforts to cut down or control substance use.
- Great deal of time spent in activities to obtain the substance, use the substance, or recover from its effects.
- Craving or strong desire to use the substance.
- Recurrent use resulting in failure to fulfill major role obligations at work, school, or home.
- Continued substance use despite persistent or recurrent social or interpersonal problems.
- Important social, occupational, or recreational activities are given up or reduced because of substance use.
- Recurrent substance use in situations in which it is physically hazardous.
- Substance use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the substance.
- Tolerance, as defined by either of the following:
- A need for markedly increased amounts of the substance to achieve desired effect
A markedly diminished effect with continued use of the same amount of substance 11.Withdrawal, as manifested by either of the following:
- Characteristic withdrawal syndrome for the substance
- Use of the substance or closely related substance is taken to relieve or avoid withdrawal symptoms
Note: Symptoms of tolerance and withdrawal occurring in the context of appropriate medical treatment with prescribed medications (e.g., opioid analgesics, sedatives, stimulants, etc.) are specifically not counted when diagnosing a substance use disorder. Furthermore, the DSM states:
“The appearance of normal, expected pharmacological tolerance and withdrawal during the course of medical treatment has been known to lead to an erroneous diagnosis of addiction, even when these were the only symptoms present.”
Use, Abuse, and Dependence
Unlike DSM-5, ICD-10-CM continues to employ the concepts of substance abuse and substance dependence.
Substance abuse represents a maladaptive pattern of drug-taking, which may include detriments to social functioning, to physical well-being, and/or to mental health in patients who have not yet reached a state of physical dependence.
Substance dependence is defined as a chronic mental and physical condition related to the patient's pattern of drug-taking that is characterized by behavioral and physiological responses, which may include:
- A compulsion to take the drug in order to experience its psychic effects, or to avoid the discomfort of its absence.
- An inability to stop the use of the drug despite strong incentives.
- Physical dependence (i.e., tolerance and withdrawal).
When documenting substance use disorders, include the following:
- Severity — Mild, moderate, etc.
- Pattern of use — Continuous use, in remission, relapsed, etc.
- Substance-induced mood/psychotic symptoms — Depression, hallucinations, anxiety, etc.
- Current presentation — Intoxication, drunkenness, withdrawal, etc.
- Treatment plan — Rehabilitation, maintenance therapy (specify drug), AA, etc.
Drug dependence in context of appropriate medical treatment — Physical dependence (i.e., tolerance and withdrawal) can develop with the chronic use of many drugs. This can include prescription drugs, even if taken as instructed. ICD-10-CM does not distinguish between this normal, expected response and other forms of drug dependence. Any type of drug dependency (i.e., prescribed, non-prescribed [illicit], physiological, and/or behavioral) is coded similarly.
The “substance use disorders” of DSM-5 are reported in ICD-10 as follows:
DSM-5 Diagnosis | ICD-10 Category |
---|---|
Substance use disorder, mild | Substance abuse |
Substance use disorder, moderate | Substance dependence |
Substance use disorder, severe (addiction)[2] | Substance dependence |
When use, abuse and dependence of the same substance are documented in the encounter note, only one code should be assigned based on the following hierarchy:
If… | Then report… |
---|---|
Both use and abuse are documented | Abuse |
Both abuse and dependence are documented | Dependence |
Use, abuse, and dependence are documented | Dependence |
Both use and dependence are documented | Dependence |
ICD-10-CM Code Selection
The presence of a condition can’t be assumed even if evidence is present in the medical record. It requires the provider’s clinical judgment and explicitly stated diagnosis. The diagnosis code reported must match the documented diagnosis assessed by the provider.
Identify the substance:[3]
- Alcohol (F10)
- Stimulant (F15) non-cocaine
- Opioid (F11)
- Hallucinogen (F16)
- Cannabis (F12)
- Nicotine (F17)
- Sedative/Hypnotic/Anxiolytic (F13)
- Inhalant (F18)
- Cocaine (F14)
- Other Psychoactive Substance (F19)
The severity is determined by the number of symptoms present in the individual.
- Mild — 2- 3
- Moderate — 4-5
- Severe — 6 or more
- In remission — Remission occurs when none of the criteria for substance use disorder (except craving) for at least three months.
- Early remission: more than three to less than 12 months
- Sustained remission: more than 12 months
Further specify any applicable detail:
- Environment or method of achieved remission.
- “In a controlled environment” — When the individual in remission is in a supervised residential setting where access to alcohol and controlled substances is restricted.
- “On maintenance therapy” — When the individual in remission is being maintained on a prescribed medication (e.g., agonist, partial agonist, agonist/antagonist, or full antagonist).
- Association with intoxication or withdraw.
- Presence of induced manifestation or complication:
- Delirium
- Perceptual disturbance
- Anxiety
- Sexual dysfunction
- Sleep or mood disorder
- Persisting amnestic disorder or dementia
- Detailed clinical diagnosis and treatment plan/condition management.

Telehealth refers to a broad collection of electronic and telecommunications technologies that support delivery of healthcare services from distant locations. Forms of telehealth include telemedicine, virtual check-ins, e-visits, and telephone visits, among others.[1]
Risk adjustment requires that reported diagnoses stem from face-to-face visits between patients and providers. Telehealth services that employ synchronous audio and video technology permitting real- time communication between patients and providers, meet the face-to-face requirement.[2]
Telemedicine
Telemedicine visits are the same as in-person visits when synchronous communications based technology is used between distant and originating sites. This includes outpatient office visits, annual wellness visits, emergency department or inpatient consultations, and individual psychotherapy.
- Technology: Interactive audio & video with real-time, two-way communication.
- Originating Site:
- Rural health professional shortage area.
- County outside a metropolitan statistical area.
- Distant Site:
- Medical facility (i.e. hospital, health clinic, physician’s office, etc.).
- Home of beneficiary receiving dialysis for ESRD or treatment for substance use disorder.
Virtual Check-Ins
Virtual check-ins are short, patient-initiated communications with a provider to determine if an office visit , remote evaluation, or a store and forward submitted by the patient is needed.
- Technology: Audio/video, audio-only, digital image/video, secure text messaging, email, or patient portal
- Originating Site: Any location, including patient’s home
E-Visits
E-visits are non-face-to-face, patient-initiated digital communications via an online portal. Once a patient generates the initial inquiry, communications can occur over a seven-day period.
- Technology: Patient portal
- Originating Site: Any location, including patient’s home
Telephone Visits
Telephone visits are non-face-to-face, patient-initiated services over the telephone.
- Technology: Telephone
A provider must have an established relationship[3] with a patient before utilizing telehealth services to treat a patient. Established relationships can be proved if:
- Provider has previously conducted an in-person exam available to provide follow-up care.
- On-call or cross-coverage arrangement exists with the patient's regular provider.
- A consulting provider agreed to supervise treatment, including follow-up care.
Key Terms[4]
- Distant site — Site at which the provider is located at the time of service.
- Originating site — Location of the patient at the time of service.
- Asynchronous or "Store and Forward" — Transfer of data from one site to another that has been recorded (stored) and sent (forwarded) via telecommunications device.
Coding and Documentation
- Verbal consent for the service should be noted and, if applicable, a statement that the patient does not require a visit unless there is a problem.
- Communications should not be related to a medical visit within the past seven days and should not lead to a medical visit within the next 24 hours (or soonest available appointment).
- All chronic, active, or status conditions (amputations, dialysis status etc.) that impact the current date of service should be clearly documented.
- Document start and stop times and/or the total visit time to meet applicable CPT requirements.
CPT©/HCPCS Codes
Code | Description |
---|---|
G2010, G2250 | Remote evaluation of pre-recorded image/video (e.g., store and forward) |
G2012, G2251-G2252 | Non-face-to-face brief medical discussion (e.g., virtual check-in) |
G0071 | RHC/FQHA communications services |
99421-99423, G2061-G2063, 98970-98972* | Non-face-to-face online digital E/M (E-Visit) |
99441-99423, 98966-98968* | Audio-only, telephone E/M service |
Telemedicine does not require a distinct set of CPT®/HCPCS codes. Report with same CPT© and Place of Service (POS) codes as the in-person visit using the 95 or GT modifier.

Hepatitis means inflammation of the liver. Toxins, certain drugs, some diseases, heavy alcohol use, bacterial, or viral infections can cause hepatitis. Hepatitis is also the name of a family of viral infections that affect the liver.
Viral Hepatitis Types[1]
Acute viral hepatitis generally resolves within a few months from the date of onset. In other cases, the disease becomes a long-term or chronic illness.
Chronic hepatitis is classified as inflammation caused by viral hepatitis lasting longer than six months. If left untreated, chronic hepatitis can cause serious health problems, including liver damage, cirrhosis, liver cancer, and even death
- Hepatitis A — Caused by ingesting contaminated water or food. Highly contagious, can also be contracted from close contact with an infected person or object.
- Hepatitis B — Spread through bodily fluids during sexual contact or through blood transfusions
- Hepatitis C — Blood-borne, spread through direct contact with infected blood. Primarily transmitted by needles shared among drug abusers, blood transfusion, hemodialysis and needle sticks, can also be transmitted by sexual contact
- Hepatitis D — Also known as delta, cannot occur in the absence of hepatitis B. Hepatitis B with delta agent is the most severe form of (acute and chronic) hepatitis[2]
- Hepatitis E — Acute condition caused by ingesting contaminated food or water, which does not lead to chronic hepatitis
The most common types are Hepatitis A, Hepatitis B, and Hepatitis C. Hepatitis A and E are acute in nature and do not lead to chronic hepatitis. Hepatitis B, C, and D viruses can cause chronic, sometimes lifelong conditions.
Signs & Symptoms
Signs and symptoms of viral hepatitis may or may not be present. Only lab tests can confirm which viral agent is present. Symptoms can include:
- Nausea
- Vomiting
- Loss of appetite
- Jaundice
- Abdominal pain
- Dry mucous membranes
- Malaise/fatigue
- Anorexia
- Ascites
- Hepato-jugular reflex
- Firm/enlarged liver
- Palmar erythema
Diagnostic Testing:
Hepatitis A (HAV)
- Hepatitis A surface antibody (HAV IgM) test detects the first antibody produced by the body when it is exposed to Hepatitis A. It detects early or recent infections and diagnoses the disease in people with symptoms of acute hepatitis.
Hepatitis B (HBV)
- Hepatitis B surface antigen (HBsAg) is present in acute and chronic infection.
- Anti-Hepatitis B core antigen (Anti-HBc IgM) is only positive during the acute phase of the infections.
Hepatitis C (HCV)
- There is no acute infectious phase serological testing available.
- Confirmation of infection determined by Anti-Hepatitis C (Anti-HCV) for initial screening, which can be confirmed with more specific testing through polymerase chain reaction (PCR) and/or nucleic acid testing (NAT).
HCV Screening and Test Results[3]
HCV Antibody Test:
Non-reactive/Negative, HCV not present
- Never had HCV
- Recent HCV infection
- 2-9 mos. to produce antibodies
- Weak immune system
- Unable to produce antibodies
Reactive/Positive, HCV present (need add’l test)
- Possible current HCV infection
- History of HCV
- Virus cleared naturally
- Virus medically treated/cured
HCV RNA Viral Load Test:
Undetectable, No HCV found in bloodstream
- Spontaneously cleared
- Medically cured
- Recently infected, less than two weeks
- Within lower limit of detection (LLOD)
- Varies, can be as low as <5 IU/mL
Detectable < LLOQ, HCV present in bloodstream less than lower limit of quantification (LLOQ)
- Amount too small to measure
Detectable
- HCV present in bloodstream
Other Chronic Hepatitis & Related Conditions
- Autoimmune hepatitis — Caused by the body’s own immune system attacking hepatic cells of the liver, typically due to genetic predisposition or environmental exposure.
- Lobular Hepatitis — Affects one or more of the four lobes (caudate, quadrate, left, right) of the liver.
- Hepatomegaly — Enlarged liver
- Hepatic fibrosis — Chronic injury or inflammation causes a buildup of scar tissue.
- Hepatic cirrhosis — Late stage of hepatic fibrosis with changes to the organ structure. Caused by many liver diseases and conditions, such as hepatitis and chronic alcoholism
- Hepatocellular carcinoma — Most common form of liver cancer, which is caused either by genetic predisposition, hepatitis, or underlying cirrhosis.
Coding and Documentation
Detailed documentation is necessary for proper code selection.
- Identify the type of hepatitis
- Indicate the acuity — Chronic, acute, with/without hepatic coma, with/without delta agent
- If viral hepatitis is not specified as acute or chronic, assign the appropriate code for unspecified viral hepatitis from Category B19.
- Viral Hepatitis in remission, any type, code to Hepatitis chronic, by type.
- For patients who have had a liver transplant, document and report the appropriate transplant status code and document any anti-rejection drugs if appropriate.
- Specify the causal agent or behavior that led to the acquisition of hepatitis.
- Refrain from using the term “History of” if a patient still has an active viral infection.
- Document treatment and follow up.
