ICD-10 Code I50.2 – Systolic (congestive) heart failure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I50.2 – Systolic (congestive) heart failure
What it is
I50.2 identifies systolic heart failure, a condition where the heart’s pumping function is reduced and it cannot eject blood effectively. In ICD-10-CM, this code is used when documentation specifies systolic or congestive systolic heart failure.
Clinical signs
Typical findings include shortness of breath, fatigue, reduced exercise tolerance, and fluid retention. Clinical features vary; refer to documentation, and code only when the record clearly supports systolic heart failure.
When to use this code
Use I50.2 when the provider documents systolic heart failure, congestive systolic heart failure, or reduced pumping function consistent with that diagnosis. It may also apply when the note links heart failure to systolic dysfunction. If the record instead states another heart failure type, code that specific type.
Do not use for
Do not use this code for diastolic heart failure, unspecified heart failure, or symptoms alone without a documented diagnosis. Check documentation when the chart only mentions edema, dyspnea, or cardiomyopathy.
Coding tip
Look for the exact heart failure type in the assessment, not just “CHF,” and query if the documentation does not specify systolic involvement.
