BillableUnspecified

Is L24.A9 billable?

Yes, but L24.A9 is an unspecified code. L24.A9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, L24.A9 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 L24.A9 — the more specific alternatives are listed below.
