About T44.2X
T44.2X is the ICD-10-CM diagnosis code for poisoning by, adverse effect of and underdosing of ganglionic blocking drugs. It belongs to category T44 (poisoning by, adverse effect of and underdosing of drugs primarily affecting the autonomic nervous 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.
