Is S11.029D billable?

Yes, but S11.029D is an unspecified code. S11.029D is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S11.029D 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 S11.029D — the more specific alternatives are listed below.
