T81.60Unspecified acute reaction to foreign substance accidentally left during a procedure

T81.60 is the ICD-10-CM diagnosis code for unspecified acute reaction to foreign substance accidentally left during a procedure. 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 T81.6, choose T81.60 (Unspecified acute reaction to foreign substance accidentally left during a procedure) only when documentation doesn't support a more specific option: aseptic peritonitis due to foreign substance accidentally left during a procedure (T81.61) and other acute reaction to foreign substance accidentally left during a procedure (T81.69).

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.
