About T81.328

T81.328 is the ICD-10-CM diagnosis code for disruption or dehiscence of closure of other specified internal operation (surgical) wound. It belongs to category T81 (complications of procedures, not elsewhere classified), block T80-T88 (complications of surgical and medical care, not elsewhere classified) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within T81.32, choose T81.328 (Disruption or dehiscence of closure of other specified internal operation (surgical) wound) only when documentation doesn't support a more specific option: disruption or dehiscence of gastrointestinal tract anastomosis, repair, or closure (T81.320), disruption or dehiscence of closure of internal operation (surgical) wound of abdominal wall muscle or fascia (T81.321) and deep disruption or dehiscence of operation wound, unspecified (T81.329).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

It was added in FY2025, effective October 1, 2024.
