About T81.32

T81.32 is the ICD-10-CM diagnosis code for disruption of internal operation (surgical) wound, not elsewhere classified. 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 7 subcodes must be used instead.

Within T81.3 (disruption of wound, not elsewhere classified), T81.32 is specifically for disruption of internal operation (surgical) wound, not elsewhere classified. Related codes cover wound, unspecified (T81.30), external operation (surgical) wound, not elsewhere classified (T81.31) and traumatic injury wound repair (T81.33).

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 has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

7th character

The appropriate 7th character is to be added to each code from category T81
