T39.4X2Poisoning by antirheumatics, not elsewhere classified, intentional self-harm

T39.4X2 is the ICD-10-CM diagnosis code for poisoning by antirheumatics, not elsewhere classified, intentional self-harm. It belongs to category T39 (poisoning by, adverse effect of and underdosing of nonopioid analgesics, antipyretics and antirheumatics), 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 T39.4X (poisoning by, adverse effect of and underdosing of antirheumatics, not elsewhere classified), T39.4X2 is specifically for poisoning by antirheumatics, not elsewhere classified, intentional self-harm. Related codes cover poisoning by antirheumatics, not elsewhere classified, accidental (unintentional) (T39.4X1), poisoning by antirheumatics, not elsewhere classified, assault (T39.4X3), poisoning by antirheumatics, not elsewhere classified, undetermined (T39.4X4), adverse effect of antirheumatics, not elsewhere classified (T39.4X5) and underdosing of antirheumatics, not elsewhere classified (T39.4X6).

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.
