What This Code Means
I50.81 is the ICD-10-CM diagnosis code for right heart failure. I50.81 sits in the ICD-10-CM chapter for diseases of the circulatory system (i00-i99), within the section covering other forms of heart disease (i30-i5a).
I50.81 is a non-billable category for right heart failure. Move through the official child-code path until the documented detail supports a reportable code.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for I50.81 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •I50.81 is a non-billable category for right heart failure. Move through the official child-code path until the documented detail supports a reportable code.
- •For this DOS, capture the provider's current assessment and the care action documented for right heart failure. Keep the checklist tied to the note.
- •Do not swap I50.81 with I50.82. The FY2026 tabular describes I50.82 as biventricular heart failure. Follow the documented detail.
- •Ask Buddy to show the official notes for I50.81 or compare its code path with I50.82.
