T41.2Poisoning by, adverse effect of and underdosing of other and unspecified general anesthetics

T41.2 is the ICD-10-CM diagnosis code for poisoning by, adverse effect of and underdosing of other and unspecified general anesthetics. It belongs to category T41 (poisoning by, adverse effect of and underdosing of anesthetics and therapeutic gases), block T36-T50 (poisoning by, adverse effects of and underdosing of drugs, medicaments and biological substances) 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 2 subcodes must be used instead.

Within T41, choose T41.2 (other and unspecified general anesthetics) only when documentation doesn't support a more specific option: inhaled anesthetics (T41.0), intravenous anesthetics (T41.1), local anesthetics (T41.3), unspecified anesthetic (T41.4) and therapeutic gases (T41.5).

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.

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