T39.1X2Poisoning by 4-Aminophenol derivatives, intentional self-harm

T39.1X2 is the ICD-10-CM diagnosis code for poisoning by 4-Aminophenol derivatives, 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 T39.1X (poisoning by, adverse effect of and underdosing of 4-Aminophenol derivatives), T39.1X2 is specifically for poisoning by 4-Aminophenol derivatives, intentional self-harm. Related codes cover poisoning by 4-Aminophenol derivatives, accidental (unintentional) (T39.1X1), poisoning by 4-Aminophenol derivatives, assault (T39.1X3), poisoning by 4-Aminophenol derivatives, undetermined (T39.1X4), adverse effect of 4-Aminophenol derivatives (T39.1X5) and underdosing of 4-Aminophenol derivatives (T39.1X6).

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.
