What ICD-10 codes are used for diastolic dysfunction?

Diastolic dysfunction, a heart condition related to how the heart fills with blood, has specific ICD-10 codes. There are no specific codes that specifically mention Diastolic dysfunction in their names, but these are the related diastolic dysfunction ICD codes you can use:

  • I50.30 - Unspecified diastolic (congestive) heart failure: This is meant to be used if the patient is confirmed to have diastolic heart failure, but it's not known/unspecified if it's acute or chronic. Once you've determined the specific type, please use either of the next two codes.
  • I50.31 - Acute diastolic (congestive) heart failure
  • I50.32 - Chronic diastolic (congestive) heart failure
  • I50.33 - Acute on chronic diastolic (congestive) heart failure: This is meant to be used when a patient is confirmed to have chronic heart failure that also gave rise to acute heart failure.
  • I50.40 - Unspecified combined systolic (congestive) and diastolic (congestive) heart failure: This is meant to be used if the patient is confirmed to have both systolic and diastolic heart failure at the same time, but it's not known/specified if it's acute or chronic. Please see either of the next two codes once you've confirmed the specific type.
  • I50.41 - Acute combined systolic (congestive) and diastolic (congestive) heart failure
  • I50.42 - Chronic combined systolic (congestive) and diastolic (congestive) heart failure

Which diastolic dysfunction ICD codes are billable?

All of the aforementioned ICD-10 codes are valid and billable.

Clinical information

Diastolic dysfunction is when the heart's ability to fill with blood is impaired. Here's what you need to know:

  • Understanding the condition: The heart is a muscle that contracts (systole) to pump blood and then relaxes (diastole) to fill with blood. Diastolic dysfunction occurs when the heart doesn't fill appropriately during the diastolic phase.
  • Symptoms: Diastolic dysfunction often doesn't have symptoms in the early stages. As it progresses, it may lead to diastolic heart failure, where symptoms such as fatigue, shortness of breath, rapid or irregular heartbeat, and edema may occur.
  • Risk factors: Aging, hypertension, diabetes, obesity, and coronary artery disease are some risk factors.
  • Diagnosis: It's diagnosed using echocardiography, which can assess the filling properties of the left ventricle.
  • Treatment: Treatment often involves managing the underlying cause, such as controlling blood pressure in hypertension or blood sugar in diabetes.

Synonyms include

  • Heart filling dysfunction
  • Diastolic heart failure
  • Left ventricular diastolic dysfunction
  • Chronic kidney disease due to diastolic dysfunction
  • Chronic systolic and diastolic congestive heart failure
  • Chronic right heart failure due to diastolic congestive heart failure
  • Ventricular failure due to diastolic congestive heart failure
  • Diastolic heart failure and shock

Commonly asked questions

Diastolic dysfunction refers to a problem with the heart's ability to fill with blood, while systolic dysfunction refers to a problem with the heart's ability to contract and pump out blood.

Treatment for diastolic dysfunction typically involves managing underlying conditions, such as hypertension or diabetes. While it may not be fully reversible, the progression of the disease can often be slowed with appropriate treatment.

Early stages of diastolic dysfunction may not have noticeable symptoms. As the condition progresses into diastolic heart failure, symptoms like fatigue, shortness of breath, rapid or irregular heartbeat, and edema may occur.
