About T44.3X5
T44.3X5 is the ICD-10-CM diagnosis code for adverse effect of other parasympatholytics [anticholinergics and antimuscarinics] and spasmolytics. 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 T44.3X, choose T44.3X5 (Adverse effect of other parasympatholytics [anticholinergics and antimuscarinics] and spasmolytics) only when documentation doesn't support a more specific option: poisoning by other parasympatholytics [anticholinergics and antimuscarinics] and spasmolytics, accidental (unintentional) (T44.3X1), poisoning by other parasympatholytics [anticholinergics and antimuscarinics] and spasmolytics, intentional self-harm (T44.3X2), poisoning by other parasympatholytics [anticholinergics and antimuscarinics] and spasmolytics, assault (T44.3X3), poisoning by other parasympatholytics [anticholinergics and antimuscarinics] and spasmolytics, undetermined (T44.3X4) and underdosing of other parasympatholytics [anticholinergics and antimuscarinics] and spasmolytics (T44.3X6).
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.
