M25.80 — Other specified joint disorders, unspecified joint

BillableUnspecified

Is M25.80 billable?

Yes, but M25.80 is an unspecified code. M25.80 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, M25.80 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 M25.80 — the more specific alternatives are listed below.
