T81.8Other complications of procedures, not elsewhere classified

T81.8 is the ICD-10-CM diagnosis code for other complications of procedures, 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 4 subcodes must be used instead.

Within T81, choose T81.8 (Other complications of procedures, not elsewhere classified) only when documentation doesn't support a more specific option: postprocedural shock (T81.1), disruption of wound, not elsewhere classified (T81.3), infection following a procedure (T81.4), complications of foreign body accidentally left in body following procedure (T81.5), acute reaction to foreign substance accidentally left during a procedure (T81.6), vascular complications following a procedure, not elsewhere classified (T81.7) and unspecified complication of procedure (T81.9).

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.

The conditions in its Excludes2 note aren't part of T81.8, but may be coded alongside it if the patient has both: hypothermia following anesthesia (T88.51) and malignant hyperpyrexia due to anesthesia (T88.3).

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.
