About T43.613

T43.613 is the ICD-10-CM diagnosis code for poisoning by caffeine, assault. 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 T43.61 (poisoning by, adverse effect of and underdosing of caffeine), T43.613 is specifically for poisoning by caffeine, assault. Related codes cover poisoning by caffeine, accidental (unintentional) (T43.611), poisoning by caffeine, intentional self-harm (T43.612), poisoning by caffeine, undetermined (T43.614), adverse effect of caffeine (T43.615) and underdosing of caffeine (T43.616).

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.
