About T45.3X2
T45.3X2 is the ICD-10-CM diagnosis code for poisoning by enzymes, intentional self-harm. It belongs to category T45 (poisoning by, adverse effect of and underdosing of primarily systemic and hematological agents, not elsewhere classified), 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 T45.3X (poisoning by, adverse effect of and underdosing of enzymes), T45.3X2 is specifically for poisoning by enzymes, intentional self-harm. Related codes cover poisoning by enzymes, accidental (unintentional) (T45.3X1), poisoning by enzymes, assault (T45.3X3), poisoning by enzymes, undetermined (T45.3X4), adverse effect of enzymes (T45.3X5) and underdosing of enzymes (T45.3X6).
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.
