About T49.92
T49.92 is the ICD-10-CM diagnosis code for poisoning by unspecified topical agent, intentional self-harm. It belongs to category T49 (poisoning by, adverse effect of and underdosing of topical agents primarily affecting skin and mucous membrane and by ophthalmological, otorhinorlaryngological and dental drugs), 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 T49.9, choose T49.92 (Poisoning by unspecified topical agent, intentional self-harm) only when documentation doesn't support a more specific option: poisoning by unspecified topical agent, accidental (unintentional) (T49.91), poisoning by unspecified topical agent, assault (T49.93), poisoning by unspecified topical agent, undetermined (T49.94), adverse effect of unspecified topical agent (T49.95) and underdosing of unspecified topical agent (T49.96).
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.
