S31.159S — Open bite of abdominal wall, unspecified quadrant without penetration into peritoneal cavity, sequela
Is S31.159S billable?
Yes, but S31.159S is an unspecified code. S31.159S is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S31.159S 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 S31.159S — the more specific alternatives are listed below.
