About T43.652

T43.652 is the ICD-10-CM diagnosis code for poisoning by methamphetamines intentional self-harm. It belongs to category T43 (poisoning by, adverse effect of and underdosing of psychotropic drugs, 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 T43.65 (poisoning by, adverse effect of and underdosing of methamphetamines), T43.652 is specifically for poisoning by methamphetamines intentional self-harm. Related codes cover poisoning by methamphetamines accidental (unintentional) (T43.651), poisoning by methamphetamines, assault (T43.653), poisoning by methamphetamines, undetermined (T43.654), adverse effect of methamphetamines (T43.655) and underdosing of methamphetamines (T43.656).

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.
