About T36.8X5
T36.8X5 is the ICD-10-CM diagnosis code for adverse effect 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 3 subcodes must be used instead.
Within T36.8X, choose T36.8X5 (Adverse effect of other systemic antibiotics) only when documentation doesn't support a more specific option: poisoning by other systemic antibiotics, accidental (unintentional) (T36.8X1), poisoning by other systemic antibiotics, intentional self-harm (T36.8X2), poisoning by other systemic antibiotics, assault (T36.8X3), poisoning by other systemic antibiotics, undetermined (T36.8X4) and underdosing of other systemic antibiotics (T36.8X6).
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.
