T43.202Poisoning by unspecified antidepressants, intentional self-harm

T43.202 is the ICD-10-CM diagnosis code for poisoning by unspecified antidepressants, 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 T43.20, choose T43.202 (Poisoning by unspecified antidepressants, intentional self-harm) only when documentation doesn't support a more specific option: poisoning by unspecified antidepressants, accidental (unintentional) (T43.201), poisoning by unspecified antidepressants, assault (T43.203), poisoning by unspecified antidepressants, undetermined (T43.204), adverse effect of unspecified antidepressants (T43.205) and underdosing of unspecified antidepressants (T43.206).

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.
