2022 ICD-10-CM Code I50

Heart failure

Version 2021

Not Valid for Submission

ICD-10:I50
Short Description:Heart failure
Long Description:Heart failure

Code Classification

  • Diseases of the circulatory system (I00–I99)
    • Other forms of heart disease (I30-I5A)
      • Heart failure (I50)

I50 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of heart failure. The code is not specific and is NOT valid for the year 2022 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding for Heart failure

Non-specific codes like I50 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for heart failure:

  • BILLABLE CODE - Use I50.1 for Left ventricular failure, unspecified
  • NON-BILLABLE CODE - I50.2 for Systolic (congestive) heart failure
  • BILLABLE CODE - Use I50.20 for Unspecified systolic (congestive) heart failure
  • BILLABLE CODE - Use I50.21 for Acute systolic (congestive) heart failure
  • BILLABLE CODE - Use I50.22 for Chronic systolic (congestive) heart failure
  • BILLABLE CODE - Use I50.23 for Acute on chronic systolic (congestive) heart failure
  • NON-BILLABLE CODE - I50.3 for Diastolic (congestive) heart failure
  • BILLABLE CODE - Use I50.30 for Unspecified diastolic (congestive) heart failure
  • BILLABLE CODE - Use I50.31 for Acute diastolic (congestive) heart failure
  • BILLABLE CODE - Use I50.32 for Chronic diastolic (congestive) heart failure
  • BILLABLE CODE - Use I50.33 for Acute on chronic diastolic (congestive) heart failure
  • NON-BILLABLE CODE - I50.4 for Combined systolic (congestive) and diastolic (congestive) heart failure
  • BILLABLE CODE - Use I50.40 for Unspecified combined systolic (congestive) and diastolic (congestive) heart failure
  • BILLABLE CODE - Use I50.41 for Acute combined systolic (congestive) and diastolic (congestive) heart failure
  • BILLABLE CODE - Use I50.42 for Chronic combined systolic (congestive) and diastolic (congestive) heart failure
  • BILLABLE CODE - Use I50.43 for Acute on chronic combined systolic (congestive) and diastolic (congestive) heart failure
  • NON-BILLABLE CODE - I50.8 for Other heart failure
  • NON-BILLABLE CODE - I50.81 for Right heart failure
  • BILLABLE CODE - Use I50.82 for Biventricular heart failure
  • BILLABLE CODE - Use I50.83 for High output heart failure
  • BILLABLE CODE - Use I50.84 for End stage heart failure
  • BILLABLE CODE - Use I50.89 for Other heart failure
  • BILLABLE CODE - Use I50.9 for Heart failure, unspecified

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code I50:


Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Information

Information for Patients


Heart Failure

Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. Heart failure does not mean that your heart has stopped or is about to stop working. It means that your heart is not able to pump blood the way it should. It can affect one or both sides of the heart.

The weakening of the heart's pumping ability causes

Common causes of heart failure are coronary artery disease, high blood pressure and diabetes. It is more common in people who are 65 years old or older, African Americans, people who are overweight, and people who have had a heart attack. Men have a higher rate of heart failure than women.

Your doctor will diagnose heart failure by doing a physical exam and heart tests. Treatment includes treating the underlying cause of your heart failure, medicines, and heart transplantation if other treatments fail.
