T36.8Poisoning by, adverse effect of and underdosing of other systemic antibiotics

T36.8 is the ICD-10-CM diagnosis code for poisoning by, adverse effect of and underdosing of other systemic antibiotics. It belongs to category T36 (poisoning by, adverse effect of and underdosing of systemic antibiotics), 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 1 subcodes must be used instead.

Within T36, choose T36.8 (other systemic antibiotics) only when documentation doesn't support a more specific option: penicillins (T36.0), cephalosporins and other beta-lactam antibiotics (T36.1), chloramphenicol group (T36.2), macrolides (T36.3), tetracyclines (T36.4), aminoglycosides (T36.5), rifampicins (T36.6), antifungal antibiotics, systemically used (T36.7) and 2 more.

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.
