About T41.3X2

T41.3X2 is the ICD-10-CM diagnosis code for poisoning by local anesthetics, intentional self-harm. It belongs to category T41 (poisoning by, adverse effect of and underdosing of anesthetics and therapeutic gases), 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 T41.3X (poisoning by, adverse effect of and underdosing of local anesthetics), T41.3X2 is specifically for poisoning by local anesthetics, intentional self-harm. Related codes cover poisoning by local anesthetics, accidental (unintentional) (T41.3X1), poisoning by local anesthetics, assault (T41.3X3), poisoning by local anesthetics, undetermined (T41.3X4), adverse effect of local anesthetics (T41.3X5) and underdosing of local anesthetics (T41.3X6).

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.
