T46.0XPoisoning by, adverse effect of and underdosing of cardiac-stimulant glycosides and drugs of similar action

T46.0X is the ICD-10-CM diagnosis code for poisoning by, adverse effect of and underdosing of cardiac-stimulant glycosides and drugs of similar action. It belongs to category T46 (poisoning by, adverse effect of and underdosing of agents primarily affecting the cardiovascular system), 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 6 subcodes must be used instead.

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.
