About T37.1X2
T37.1X2 is the ICD-10-CM diagnosis code for poisoning by antimycobacterial drugs, intentional self-harm. 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 T37.1X (poisoning by, adverse effect of and underdosing of antimycobacterial drugs), T37.1X2 is specifically for poisoning by antimycobacterial drugs, intentional self-harm.
