S91.146S — Puncture wound with foreign body of unspecified lesser toe(s) without damage to nail, sequela
Is S91.146S billable?
Yes, but S91.146S is an unspecified code. S91.146S is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S91.146S 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 S91.146S — the more specific alternatives are listed below.
