S52.046S — Nondisplaced fracture of coronoid process of unspecified ulna, sequela

BillableUnspecified

Is S52.046S billable?

Yes, but S52.046S is an unspecified code. S52.046S is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S52.046S 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 S52.046S — the more specific alternatives are listed below.
