T37.2X3Poisoning by antimalarials and drugs acting on other blood protozoa, assault

T37.2X3 is the ICD-10-CM diagnosis code for poisoning by antimalarials and drugs acting on other blood protozoa, assault. It belongs to category T37 (poisoning by, adverse effect of and underdosing of other systemic anti-infectives and antiparasitics), 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 T37.2X, choose T37.2X3 (Poisoning by antimalarials and drugs acting on other blood protozoa, assault) only when documentation doesn't support a more specific option: poisoning by antimalarials and drugs acting on other blood protozoa, accidental (unintentional) (T37.2X1), poisoning by antimalarials and drugs acting on other blood protozoa, intentional self-harm (T37.2X2), poisoning by antimalarials and drugs acting on other blood protozoa, undetermined (T37.2X4), adverse effect of antimalarials and drugs acting on other blood protozoa (T37.2X5) and underdosing of antimalarials and drugs acting on other blood protozoa (T37.2X6).

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.
