S31.11AS — Laceration without foreign body of abdominal wall, unspecified flank without penetration into peritoneal cavity, sequela
Is S31.11AS billable?
Yes, but S31.11AS is an unspecified code. S31.11AS is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S31.11AS 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 S31.11AS — the more specific alternatives are listed below.
