      (Z77-Z99)

Z82.49 is a billable diagnosis code used to specify a medical diagnosis of family history of ischemic heart disease and other diseases of the circulatory system. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

This code describes a circumstance which influences the patient's health status but not a current illness or injury. The code is unacceptable as a principal diagnosis.

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • Unacceptable principal diagnosis - There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Present on Admission (POA)

Z82.49 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Patient Education


Family History

Your family history includes health information about you and your close relatives. Families have many factors in common, including their genes, environment, and lifestyle. Looking at these factors can help you figure out whether you have a higher risk for certain health problems, such as heart disease, stroke, and cancer.

Having a family member with a disease raises your risk, but it does not mean that you will definitely get it. Knowing that you are at risk gives you a chance to reduce that risk by following a healthier lifestyle and getting tested as needed.

You can get started by talking to your relatives about their health. Draw a family tree and add the health information. Having copies of medical records and death certificates is also helpful.

Heart Diseases

What is heart disease?

Heart disease is a general term that includes many types of heart problems. It's also called cardiovascular disease, which means heart and blood vessel disease.

Heart disease is the leading cause of death in the United States, but there are ways to prevent and manage many types of heart disease.

What are the types of heart disease?

There are many different types of heart disease. Some you may be born with, called congenital heart disease. Other types develop during your lifetime.

Coronary artery disease (also called coronary heart disease) is the most common type of heart disease. It happens slowly over time when a sticky substance called plaque builds up in the arteries that supply your heart muscle with blood. The plaque narrows or blocks blood flow to the heart muscle and can lead to other heart problems:

  • Angina - chest pain from lack of blood flow
  • Heart attacks - when part of the heart muscle dies from loss of blood flow
  • Heart failure - when your heart can't pump enough blood to meet your body's needs
  • Arrhythmia - a problem with the rate or rhythm of your heartbeat

Other types of heart diseases may affect your heart valves or heart muscle (cardiomyopathy).

What causes heart diseases?

The causes of heart disease depend on the type of disease. Some possible causes include lifestyle, genetics, infections, medicines, and other diseases.

Who is more likely to develop heart diseases?

There are many different factors that can make you more likely to develop heart disease. Some of these factors you can change, but others you cannot.

  • Age. Your risk of heart disease goes up as you get older.
  • Sex. Some factors may affect heart disease risk differently in women than in men.
  • Family history and genetics. A family history of early heart disease raises your risk of heart disease. And research has shown that some genes are linked to a higher risk of certain heart diseases.
  • Race/ethnicity. Certain groups have higher risks than others.
  • Lifestyle habits. Over time, unhealthy lifestyle habits can raise your risk heart disease:
    • Eating a diet high in saturated fats, refined carbohydrates, and salt.
    • Not getting enough physical activity.
    • Drinking too much alcohol.
    • Smoking and exposure to secondhand smoke.
    • Too much stress.
  • Having other medical conditions can raise your risk of heart diseases. These conditions include:
    • High blood pressure.
    • High cholesterol levels.
    • Diabetes.
    • Obesity.
    • Autoimmune and inflammatory diseases.
    • Chronic kidney disease.
    • Metabolic syndrome.

What are the symptoms of heart disease?

Your symptoms will depend on the type of heart disease you have. You may not have symptoms at first. In some cases, you may not know you have heart disease until you have a complication such as a heart attack.

How are heart diseases diagnosed?

To find out if you have heart disease, your health care provider will:

  • Ask about your medical history, including your symptoms
  • Ask about your family health history, including relatives who have had heart disease
  • Do a physical exam
  • Likely run heart tests and blood tests

In some cases, your provider may refer you to a cardiologist (a doctor who specializes in heart diseases) for tests, diagnosis, and care.

What are the treatments for heart disease?

Treatment plans for heart disease depend on the type of heart disease you have, how serious your symptoms are, and what other health conditions you have. Possible treatments may include:

  • Heart-healthy lifestyle changes
  • Medicines
  • Procedures or surgeries
  • Cardiac rehabilitation

Can heart diseases be prevented?

You may be able to lower your risk of certain heart diseases by making heart-healthy lifestyle changes and managing any other medical conditions you have.
