S31.60AD — Unspecified open wound of abdominal wall, unspecified flank with penetration into peritoneal cavity, subsequent encounter
Is S31.60AD billable?
Yes, but S31.60AD is an unspecified code. S31.60AD is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S31.60AD 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 S31.60AD — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from S31
The conditions below can never be reported together with S31.60AD on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code — inherited from Chapter 19
Report an additional code alongside S31.60AD to fully describe the condition. S31.60AD is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
