ICD-10 Code I50.812 – Chronic right heart failure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I50.812 – Chronic right heart failure
What it is
I50.812 identifies chronic right-sided heart failure, meaning the right ventricle is not pumping effectively over time. Use it when documentation specifically states chronic right heart failure.
Clinical signs
Common findings include peripheral edema, jugular venous distention, hepatic congestion, and abdominal swelling. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic right heart failure, chronic right-sided CHF, or equivalent wording. It may appear as a primary cardiac diagnosis or as a complication of another documented heart condition. If the record only says heart failure without side specificity, check documentation.
Do not use for
Do not use it for acute right heart failure unless chronic is documented. Do not assign it for unspecified heart failure or isolated left-sided failure.
Coding tip
Code the side and chronicity only when the provider clearly documents both; otherwise, query or check documentation.
