ICD-10 Code I50.22 – Chronic systolic (congestive) heart failure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I50.22 – Chronic systolic (congestive) heart failure
What it is
This code identifies chronic heart failure caused by impaired left ventricular systolic function, meaning the heart does not pump effectively. Use it when the record specifically documents chronic systolic heart failure, with or without congestion.
Clinical signs
Clinical features may include dyspnea, fatigue, reduced exercise tolerance, edema, or signs of fluid overload. Documentation may also note reduced ejection fraction or left ventricular systolic dysfunction; if uncertain, refer to documentation.
When to use this code
Use I50.22 when the provider documents chronic systolic heart failure, chronic HFrEF, or chronic left-sided systolic failure. It is appropriate for ongoing management visits, follow-up care, or encounters where the condition remains active. If the note says only “CHF,” you may need clarification.
Do not use for
Do not use this code for acute systolic heart failure or for heart failure type not specified as systolic. Check documentation if the record describes diastolic, combined, or unspecified heart failure.
Coding tip
Code the documented heart failure type exactly; if systolic and chronic are not both stated, query the provider.
