ICD-10 Code I50.89 – Other heart failure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I50.89 – Other heart failure
What it is
I50.89 identifies heart failure that does not fit a more specific ICD-10-CM heart failure category. Use it when the record clearly supports heart failure, but the documentation does not specify the type.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include shortness of breath, fluid retention, fatigue, and signs of poor cardiac pumping function, but you should code only what is documented.
When to use this code
Use I50.89 when the provider documents heart failure and no more specific code applies, such as systolic, diastolic, or combined heart failure. It may also fit cases described with another nonstandard or unspecified heart failure term. If the record is unclear, check documentation before assigning the code.
Do not use for
Do not use this code when the documentation supports a more specific heart failure diagnosis. Avoid it for cases that are truly unspecified without enough detail; check documentation.
Coding tip
Code the most specific heart failure type documented, and use I50.89 only when the record supports heart failure but does not name a more precise category.
