ICD-10 Code I50.84 – End stage heart failure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I50.84 – End stage heart failure
What it is
I50.84 identifies end stage heart failure, meaning advanced cardiac failure with severe, persistent impairment despite appropriate management. Use it when documentation clearly states end stage disease.
Clinical signs
Clinical features vary; refer to documentation. Typical records may describe profound exercise intolerance, recurrent decompensation, or symptoms at rest, but you should code only when the provider documents end stage heart failure.
When to use this code
Use I50.84 when the clinician explicitly documents end stage heart failure in the assessment, problem list, or discharge summary. It may also apply when the provider states advanced or terminal heart failure and links that wording to end stage disease. If the note is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for unspecified heart failure, chronic heart failure without end stage wording, or isolated cardiomyopathy. If the record does not clearly support end stage status, do not infer it.
Coding tip
Code I50.84 only from explicit provider documentation; if needed, query for clarification rather than assuming severity.
