S09.0XXS — Injury of blood vessels of head, not elsewhere classified, sequela
Is S09.0XXS billable?
Yes, but S09.0XXS is an unspecified code. S09.0XXS is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S09.0XXS 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 S09.0XXS.
