Is O29.029 billable?

Yes, but O29.029 is an unspecified code. O29.029 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, O29.029 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 O29.029 — the more specific alternatives are listed below.
