ICD-10 Code I50.82 – Biventricular Heart Failure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I50.82 – Biventricular heart failure
What it is
I50.82 identifies heart failure involving both the right and left ventricles. Use it when documentation clearly states biventricular or combined ventricular failure.
Clinical signs
Clinical features may include signs of both left-sided and right-sided heart failure, such as dyspnea, edema, fatigue, and congestion. Clinical features vary; refer to documentation.
When to use this code
Use I50.82 when the provider documents biventricular heart failure, combined ventricular failure, or failure affecting both ventricles. Apply it when the record supports involvement of both sides rather than a single-sided heart failure type. Check documentation if the note is unclear.
Do not use for
Do not use this code for isolated left-sided or right-sided heart failure, or for nonspecific heart failure without ventricular detail. If the record only says “heart failure,” code to the documented type.
Coding tip
Assign I50.82 only when both ventricles are explicitly documented; otherwise, query or code the more specific stated heart failure.
