BillableUnspecified

Is T39.94XD billable?

Yes, but T39.94XD is an unspecified code. T39.94XD is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, T39.94XD 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 T39.94XD — the more specific alternatives are listed below.
