About T44.2X2

T44.2X2 is the ICD-10-CM diagnosis code for poisoning by ganglionic blocking drugs, intentional self-harm. 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 3 subcodes must be used instead.

Within T44.2X (poisoning by, adverse effect of and underdosing of ganglionic blocking drugs), T44.2X2 is specifically for poisoning by ganglionic blocking drugs, intentional self-harm. Related codes cover poisoning by ganglionic blocking drugs, accidental (unintentional) (T44.2X1), poisoning by ganglionic blocking drugs, assault (T44.2X3), poisoning by ganglionic blocking drugs, undetermined (T44.2X4), adverse effect of ganglionic blocking drugs (T44.2X5) and underdosing of ganglionic blocking drugs (T44.2X6).

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.
