T81.328S — Disruption or dehiscence of closure of other specified internal operation (surgical) wound, sequela
Is T81.328S billable?
Yes, but T81.328S is an unspecified code. T81.328S is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, T81.328S 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 T81.328S.

Excludes1 — never code together — inherited from T81.3
The conditions below can never be reported together with T81.328S 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 T81.328S to fully describe the condition. T81.328S is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from T80-T88
Report an additional code alongside T81.328S to fully describe the condition. T81.328S is sequenced first.
