I09.89 — Other specified rheumatic heart diseases
Is I09.89 billable?
Yes, but I09.89 is an unspecified code. I09.89 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, I09.89 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting I09.89 — the more specific alternatives are listed below.
