The ICD-10 code for Congestive Heart Failure (CHF) is I50.9, Heart failure, unspecified.
Congestive heart failure occurs when the heart is unable to pump blood effectively, leading to fluid buildup in the lungs and other parts of the body. ICD-10 codes help classify different types and severities of heart failure for accurate medical documentation and billing.
Common ICD-10 Codes for CHF:
| ICD-10 Code | Description |
|---|---|
| I50.1 | Left ventricular failure |
| I50.20 | Unspecified systolic (congestive) heart failure |
| I50.21 | Acute systolic (congestive) heart failure |
| I50.22 | Chronic systolic (congestive) heart failure |
| I50.23 | Acute on chronic systolic (congestive) heart failure |
| I50.30 | Unspecified diastolic (congestive) heart failure |
| I50.31 | Acute diastolic (congestive) heart failure |
| I50.32 | Chronic diastolic (congestive) heart failure |
| I50.33 | Acute on chronic diastolic (congestive) heart failure |
| I50.40 | Unspecified combined systolic and diastolic heart failure |
| I50.41 | Acute combined systolic and diastolic heart failure |
| I50.42 | Chronic combined systolic and diastolic heart failure |
| I50.43 | Acute on chronic combined systolic and diastolic heart failure |
| I50.9 | Heart failure, unspecified |
Key Point:
Use I50.9 when documentation does not specify the type or chronicity of the heart failure. Always select the most specific ICD-10 code that reflects the patient’s condition and medical documentation.
