Is N80.C0 billable?

Yes, but N80.C0 is an unspecified code. N80.C0 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, N80.C0 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 N80.C0 — the more specific alternatives are listed below.
