Risk Adjustment is the method developed and used by the Department of Health & 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; or 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 & 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 conditions, 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 & Wellness is required to validate member diagnosis annually through Risk Adjustment Data Validation (RADV) audit. Health Plans also engage in chart review projects to ensure member diagnosis are being reported accurately.
Arkansas Health & Wellness engages providers through various incentive programs that reward providers for risk adjustment gap closure.
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.
- Heart attack
- Abnormal heart valve
- Coronary artery disease
- Emphysema /Lung Disease
- Congenital defects
- Viral infections
- Metabolic imbalance
- Thyroid disorder
- Chest pain
- Weakness / fatigue
- Blood pressure change
- Shortness of breath
- No symptoms
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 persist 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 sick sinus syndrome 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.
Patients who have a rapid heart rate as part of their SSS may need additional treatments after pacemaker placement to control fast rhythms.
- 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.
Coding & Documentation
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.
- 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
- 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
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 3 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 classifies CKD by the severity level of decreased kidney function.
Mild kidney damage (normal function)
Mildly decreased renal function
Stage 3, unspecified severity
Mild to Moderate
Moderate to Severe
Renal disease, renal insufficiency or renal failure NOS.
The GFR value may 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 condition.
Signs and Symptoms
Patients with CKD stages 1-3 are generally asymptomatic. Typically, it is not until stages 4-5 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
- Blood in urine or protein in urine
- Chest pain
- Twitching in the muscles and cramps
- Shortness of breath
- Erectile dysfunction, amenorrhea, decreased libido
- Platelet dysfunction with tendency to bleed
- Loss of appetite
- High blood pressure (hypertension)
Coding & Documentation
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.- 
End Stage Renal Disease
End-stage renal disease (ESRD) is when the kidneys permanently fail to work. ESRD requires renal dialysis or kidney transplant.
- N18.6, is assigned when ESRD is documented by provider
- Also 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
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 is a pathologic manifestations 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

AMB21-AR-H-111 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.
Types of COPD
Chronic bronchitis - hypersecretion of mucus with chronic productive cough lasting more than 3 months in 2 consecutive years
- 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 & 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
80% or greater
Persistent dry cough, shortness of breath during exertion
79% - 50%
Persistent cough with excess mucus, shortness of breath during mild activity, wheezing, fatigue, sleep disturbance
49% - 30%
Frequent respiratory infections, edema, cyanosis, tightness in chest, trouble breathing while performing basic tasks, difficulty taking a deep breath
29% or less
Constant wheezing and shortness of breath, inability to inhale deeply increased heart rate and blood pressure, loss of appetite and weight
COPD Treatment & 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
- Bullectomy – removal of air space from collapsed air sacs
- Lung transplant – replace diseased lung with a healthy one
- Oxygen therapy – reduces shortness of breath
- Smoking cessation – slows progression
- Bronchodilators – opens airways
- Corticosteroids – reduces inflammation
- Lung volume reduction – removes diseased lung tissue
- Pulmonary rehabilitation –includes disease management, exercise, and counseling
- Vaccines – lower risk of flu or pneumonia
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.
- Allergic - Dust mites, Mold, Pollen, Pets, Household pests
- Non-allergic - Cold air, Medications, Household chemicals, Air pollution, Tobacco smoke, Infection
- 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 and complications of the disease: (J45.-)
- Mild, moderate, severe
- Intermittent, persistent
- Uncomplicated, with acute exacerbation, with status asthmaticus
Document diagnostic test results and any clinical findings that support the diagnosis along with disease status and treatment plan.
- 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
- Bronchoscopy – procedure using a small camera on the end of a long flexible tube, or scope, to look at air passages
- Endobronchial Ultrasound (EBUS) – bronchoscopy performed using scope with an ultrasound probe attached
- Lung biopsy – procedure to collect a tissue sample used in disease diagnosis
- Spirometry – measures volume capacity and the force of air expelled from the lungs
- Peak Expiratory Flow (PEF) – measures speed of air blown out of the lungs using maximum effort
- Fractional exhaled nitric oxide (FeNO) test - measures levels of nitric oxide exhaled from a breath
- Bronchoprovocation – tests pulmonary response or reaction to the drug methacholine.
- Pulse oximeter (Pulse Ox) - measures the saturation of oxygen carried in your red blood cells
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 & Documentation
ICD-10 code assignment depends on documentation detail 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 Code 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
- Dependence on respirator [ventilator] status (Z99.11) - Use of respirator or ventilator for life support
- 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)

AMB21-AR-H-143 Updated on November 15, 2021
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 most commonly overlooked. 
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. 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
Lifelong chronic conditions often require ongoing medical attention and the associated diagnosis 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.

 ICD-10-CM Chapter 21: Factors influencing health status and contact with health services
 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.
- Coronary artery disease
- Congenital heart disease
- Sleep apnea
- Severe lung disease
Signs & 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
- Pulmonary embolism
- Severe infections or allergic reaction
- Acute on chronic heart failure occurs when there is an acute decompensation of chronic heart failure.
Coding & 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 congestive heart failure.
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
Diabetes is a disease that occurs when glucose in the blood (blood sugar) is not controlled due to a malfunction of the body’s insulin production. Insulin is necessary to break glucose so that it can enter the body’s cells. High blood sugar from diabetes can lead to other major health problems.
Signs & Symptoms
- Frequent urination
- Increased thirst or higher water intake
- Constant hunger - even after eating
- Extreme fatigue
- Slow healing wounds or bruises
- Unexplained weight loss
- Tingling, pain, or numbness in hands/feet
- Blurry vision
Diabetes Type & ICD-10-CM Category,
- Type I – Category E10
- Insulin-dependent - the body does not produce insulin
- Sometimes called juvenile diabetes because it usually develops during childhood or adolescence.
- Sudden onset of symptoms
- Type II – Category E11
- The body does not use the insulin it produces efficiently
- Symptoms gradually progress
- Treatment may include a combination of medications, exercise, and diet.
- Gestational – Category O24
- Insulin produced by mother is blocked by pregnancy hormones increasing blood sugar.
- Excess glucose is sent to the fetus and stored as fat.
- Typically resolves once the baby is born.
- Glucose intolerance that develops from disorders or conditions other than type 1, type 2 or gestational diabetes.
- Due to underlying condition (E08.-)
- Drug or chemical induced (E09.-)
- Other specified diabetes, NEC (E13.-)
Coding & Documentation
The provider should document all know condition details and the state the specific diagnosis. Document test results and any clinical findings that support diabetes along with disease status and treatment plan.
Assign the ICD-10-CM code to the highest level of specificity found in the medical record.
Diabetes combination codes include:
- Type of diabetes
- Body System affected
- Complication/Manifestation affecting the body system
The word “with” should be interpreted to mean “associated with” or “due to” when it appears in a code title, the Alphabetic Index, or an instructional note in the Tabular List.
- Any condition indexed under “with” does not have to be linked by the provider. If the “with” condition is unrelated to diabetes, it must be specifically documented.
- The link must be documented when a relationship exists between diabetes and another condition not found under “with” before assigning the diabetic complication code.
- A patient may have diabetic complications in more than one body system. Report as many codes from categories E08 – E13 as are needed to identify all associated conditions.
Follow ICD-10 coding guidelines for code assignment and sequencing. Report codes for diabetic manifestations, underlying conditions, and the controlling agents when instructed.
Link must be documented

Poor Control & Uncontrolled
The terms “poor control” and “uncontrolled” are not interchangeable. Poorly controlled diabetes refers to diabetic hyperglycemia. There is not an index reference for “uncontrolled” diabetes. If hyperglycemic or hypoglycemic is not specified, the default code, E11.9 (diabetes, unspecified), is assigned.

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 & Reporting Refer to the Medicare Claims Processing Manual2 for additional information.
1500 Claim Form Instructions (PDF) - Coming soon
Health Insurance Claim Form (PDF) - Coming soon
- 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
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.
MEAT & 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
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.
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.
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.
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.
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.
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.
 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.

 ICD-10-CM Official Guidelines for Coding and Reporting (PDF)
The Official ICD-10-CM Guidelines 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.
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 & 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)
- Code H35.0, Background retinopathy and retinal vascular changes with the applicable code from category I10-I15
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

Ischemic Heart Disease
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).
- Poor diet
- High cholesterol
- Lack of exercise
- Family history
- Poor dental health
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 is chest pain or discomfort caused when the heart muscle does not get enough oxygen-rich blood. It is usually a symptom of and underlying heart condition such as coronary artery atherosclerosis.
SIGNS & 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, dizziness
TYPES & SEVERITY:
- Stable – Pain 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.

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 a 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 slow 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.
- 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
Cardiac arrest is triggered by an irregular heartbeat (arrhythmia) affecting the heart’s ability to pump blood to other the brain organs. Cardiac arrest occurs suddenly, often without warning. It is reversible if treated within the first few minutes but without quick intervention, is fatal.
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.
- I25.2, old MI – healed myocardial infarction or MI older than 4 weeks (28 days).
Category I21 – Acute MI
- Type 1 - initial myocardial infarction from onset up to 4 weeks (28 days) old.
- Unspecified AMI or unspecified type is assigned I21.9
- Types 3-5 are coded I21.A9
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)
AMB21-AR-H-110 Updated on October 21, 2021
Major Depressive Disorder
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 condition) 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, are used to identify the presence and level of severity.
0 – 4
None – Minimal
Education on available supportive services
5 – 9
Watchful waiting: Repeat PHQ-9 at follow-up Visit
10 – 14
Treatment Plan: Consider Counseling and/or medication, follow-up visits
15 – 19
Active Treatment: Pharmacotherapy and / or psychotherapy, follow-up visits
20 – 27
Immediate initiation of pharmacotherapy, expedited referral to mental health specialist for psychotherapy and / or collaborative management
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
- Extreme low energy and fatigue
- Decreased self-esteem
- Difficulty concentrating or making decisions
- Lasting sad, anxious, or empty mood
- Disturbance in sleep/wake cycle
Bipolar Type 1
Bipolar Type 2
|Marked by manic episodes||
Marked by hypomanic episodes
|Hospitalization due to mania likely||Hospitalization due to hypomania less likely|
|Psychosis may occur during manic episodes||Psychosis UNLIKELY to occur during hypomania|
This disorder affects the way a person thinks, feels and acts. If 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.
Symptoms of Schizophrenia:
- Lack of focus
- Difficulty completing tasks
- Extreme disorganized thoughts
- Movement disorders
- Impaired memory
- 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. 
- 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 been previously been diagnosed, 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.

AMB21-AR-H-144 Updated on November 15, 2021
Neoplasms & Cancer
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 & lymph vessels, tendons & 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 & 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, & III
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.
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
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
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)
Hormone Therapy (Z79.890)
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 or 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

AMB21-AR-H-109 Updated on October 18, 2021
Pregnancy is the period of time between conception and delivery in which a fetus develops inside the uterus. This time is divided into trimesters.
- 1st Trimester: Less than 14 weeks
- 2nd Trimester: 14 weeks - 28 weeks
- 3rd Trimester: 28 weeks - delivery
Gestational age is the age of the developing fetus. It begins on the first day of the mother’s last menstrual period and ends at birth (~40 weeks). Document the gestation in weeks and days
Childbirth begins with the true onset of labor and ends after the delivery of the baby and placenta. This is divided into three stages for vaginal deliveries.
- Begins with onset of contractions.
- Ends when cervix 10 cm dilated.
- Begins when cervix fully dilated.
- Ends with delivery of baby.
- Begins after baby delivered.
- Ends after placenta delivery.
- Puerperium – the approximately 6 week period after delivery when the mother’s body adjusts back to a non-pregnant state.
- Products of conception – tissues that develop during pregnancy (fetal tissue, placenta tissue, etc.)
- Ectopic – a pregnancy that implants outside of the uterus.
- Abortion – premature induced or spontaneous passing of the products of conception
- A spontaneous abortion, or miscarriage, is spontaneous loss of the fetus before the 20th week of pregnancy
- A missed abortion refers to a delayed miscarriage
- A threatened abortion refers to a hemorrhage in early pregnancy
- Perinatal – the period of time before birth through the 28th day following birth.
- Congenital – a condition that is present from birth.
Coding & Documentation
It is important to document condition details to the highest known degree so the diagnosis can be coded to the highest specificity. Documentation should include:
- Patients pregnancy by week of gestation
- Normal or high risk pregnancy and reason for being high-risk, if applicable
- Underlying or pre-existing conditions
- Number of fetuses, if multiple and number or alpha assigned to each (e.g., 1-8, A-H)
- Delivery outcome and location of delivery
- Normal, full term, uncomplicated
Specify any complications and fetal presentation
Include the diagnosis in the Assessment and Plan when a condition and the supporting evidence is documented during a face-to-face encounter. Include the ICD-10 Diagnosis Code for all documented conditions on the claim form. This includes chronic conditions, even if stable.
Encounter for Delivery
- Full-term uncomplicated vaginal delivery
- C-section without indication
- Other malposition
Labor & Delivery Complications
- Cord around neck
- First-fourth degree perineal laceration
- Rupture of uterus during labor
ICD-10-CM Guidelines for Coding & Reporting
Chapter 15 - Pregnancy, Childbirth, and the Puerperium (O00-O9A)
- Chapter 15 codes have sequencing priority over codes from other chapters.
- Use additional codes from other chapters to further specify conditions when applicable.
- Use codes O00-O9A only on the maternal record, never on the record of the newborn.
- A code from Category Z34, Encounter for supervision of normal pregnancy, should be used as the first-listed diagnosis for routine outpatient prenatal visits when no complications are present.
- Report code Z33.1, Pregnant state, incidental when pregnancy is documented as incidental to the encounter instead of codes from Chapter 15.
- It is the provider’s responsibility to state that the condition being treated is not affecting the pregnancy.
- The provider’s documentation of the number of weeks may be used to assign the appropriate code identifying the trimester.
- A code from Category O09, Supervision of high-risk pregnancy, should be used as the first-listed diagnosis for routine prenatal outpatient visits for patients with high-risk pregnancies.
- Use only during the prenatal period.
- Use applicable chapter 15 codes for complications during the labor or delivery episode as a result of a high-risk pregnancy.
- When there is an “in childbirth” option for the obstetric complication being coded, the “in childbirth” code should be assigned.
- Code the appropriate Encounter for full-term uncomplicated delivery if there are no complication during the labor or delivery episode.
- Other Chapter 15 codes may be used in conjunction with these codes if appropriate.

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.
Annual Physical Exams
Annual Physicals or Routine Comprehensive Physical Exams (CPE) are performed without relationship to treatment or diagnosis for a specific illness, symptom, complaint, or injury. The extent and focus of exam depends on the age and gender of the patient. An annual CPE includes an appropriate history/exam with risk counseling and/or intervention
Exam Description and CPT© Code
Less than 1 year
1 – 4 years
5 – 11 years
12 – 17 years
18 – 39 years
40 – 64 years
65 years and older
How should diagnosis codes be reported?
Category Z00 includes codes for Routine Health Exams “with” or “without” abnormal findings and should be the primary diagnosis. Report additional codes, if applicable, for pre-existing and chronic conditions as well as newly discovered conditions and/or abnormalities documented during the routine exam, regardless of whether the finding requires an additionally reported service.
General adult medical examination
Routine child health examination
|Newborn and infant health examinations
(as appropriate for age)
Follow the current year’s Official ICD-10-CM Guidelines for Coding and Reporting
What can be reported with the CPE?
• Other procedures
• Risk/Benefit Counseling
Tobacco smoking cessation counseling and substance abuse screening/intervention are included with CPE. Refer the current year’s CPT® Code book for further guidance and to view 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 CPE (99381 - 99387, 99391 – 99397)

Sepsis, Severe Sepsis, & Septic Shock
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 & 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 & 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.
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 and 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.

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
AMB21-AR-H-147 Updated on November 16, 2021
A Cerebrovascular accident (CVA), also known as a stroke, occurs when there is an interruption to blood flow that supplies oxygen to the brain. 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 - bleed into the brain caused by a broken blood vessel
A stroke is an emergent event that requires treatment in an acute care setting.
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 transischemic 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.
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 dominant or non-dominate side, and specify the type of event as the causing the sequelae
- 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
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).
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.
- Category I60 – I62: Non-traumatic cerebral hemorrhage
- Category I63: Cerebral Infarction
- Category I65 – I68: 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

In the fifth 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.
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, 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
- 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) 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, & 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
- 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:
Substance use disorder, mild
Substance use disorder, moderate
Substance use disorder, severe (addiction) 
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:
Both use and abuse are documented
Both abuse and dependence are documented
Use, abuse and dependence are documented
Both use and dependence are documented
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 & explicitly stated diagnosis. The diagnosis code reported must match the documented diagnosis assessed by the provider.
Identify the substance:
- 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 to 3
- Moderate – 4 to 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 3 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
- perceptual disturbance
- sexual dysfunction
- sleep or mood disorder
- persisting amnestic disorder or dementia
- Detailed clinical diagnosis and treatment plan/condition management

AMB21-AR-H-146 Updated on November 16, 2021
Peripheral Vascular Disease (PVD) describes any disorder of the blood vessels outside the heart and chest or disorders that affect blood flow through the arteries and/or veins.
Peripheral Vascular Disease (PVD) is also known as:
- Peripheral artery disease (PAD)
- Peripheral arterial insufficiency
- (Intermittent) claudication
- Peripheral angiopathy
- Spasm of artery
ICD-10-CM code I73.9 - Peripheral vascular disease, unspecified is assigned for all conditions listed above when documented in the medical record.
Arteriosclerosis is the hardening of the arteries. Atherosclerosis is a pattern of arteriosclerosis in which the artery narrows due to the buildup of plaque (fatty deposits) inside the artery the wall.
These conditions are applicable to ICD-10-CM Category I70:
- Arteriosclerotic vascular disease
- Arteriovascular degeneration
- Endarteritis deformans or obliterans
- Senile arteritis
- Senile endarteritis
- Vascular degeneration
PVD due to atherosclerosis should be documented, if applicable, to correctly assign codes with higher specificity. Note: Atherosclerosis of extremities; unspecified refers to type, not location.
Signs & Symptoms
- Claudication - foot, calf, buttock, hip or thigh pain or discomfort when walking that is relieved by rest.
- Cyanosis - bluish discoloration of the skin resulting from poor circulation.
- Femoral or Carotid bruit - vascular murmur sound heard over a partially occluded blood vessel on auscultation.
- Slow healing wound or skin infection
- Slow capillary refill
- Numb/painful sensations in extremities
- Atrophic skin changes
- Decreased nail growth
- Abnormal or diminished pedal pulses
- Non-pressure ulcer
- Toes or feet appear pale or discolored
- Ischemic rest pain
Abnormal physical exam findings must be confirmed with diagnostic testing.
- Ankle brachial index (ABI)
- CT angiogram (CTA)
- Doppler ultrasound
Other vascular diseases:
- Deep vein thrombosis
- Varicose veins
- Chronic venous insufficiency
- Critical limb-threatening ischemia
Complications & Interventions
Early interventions can the lower the risk of complications.
- Limited mobility
- Heart attack
- Healthy diet
- Regular exercise
- Lose weight
- Quit smoking
- Thrombolysis (CDT)
Coding & Documentation
Include the following details in the medical record:
- Cause (e.g., atherosclerosis, stenosis)
- Location of vein/artery affected (leg, foot, heal, ankle, calf, thigh)
- Laterality – specify left, right or bilateral
- Status of the artery (e.g., native, bypass graft, autologous, non-autologous biological)
- Complications such rest pain, intermittent claudication, ulceration (document ulcer site) or gangrene.
Document diagnostic test results and any clinical findings that support PVD along with disease status and treatment plan.
Also include the following details, when applicable:
- Risk factors (e.g., tobacco use, high cholesterol, morbid obesity)
- Counseling provided to patient (e.g., smoking cessation)
- Co-morbidities such as HTN, DM, and CAD with disease status and treatment plan.

”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
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
- 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.
- Loss of Appetite
- Abdominal pain
- Dry mucous membranes
- Hepato-jugular reflex
- Firm/enlarged liver
- Palmar erythema
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 systems 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 &Test Results
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 2wks
- 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
- 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 & 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.
