T44.5X4Poisoning by predominantly beta-adrenoreceptor agonists, undetermined

T44.5X4 is the ICD-10-CM diagnosis code for poisoning by predominantly beta-adrenoreceptor agonists, undetermined. 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 T44.5X (poisoning by, adverse effect of and underdosing of predominantly beta-adrenoreceptor agonists), T44.5X4 is specifically for poisoning by predominantly beta-adrenoreceptor agonists, undetermined. Related codes cover poisoning by predominantly beta-adrenoreceptor agonists, accidental (unintentional) (T44.5X1), poisoning by predominantly beta-adrenoreceptor agonists, intentional self-harm (T44.5X2), poisoning by predominantly beta-adrenoreceptor agonists, assault (T44.5X3), adverse effect of predominantly beta-adrenoreceptor agonists (T44.5X5) and underdosing of predominantly beta-adrenoreceptor agonists (T44.5X6).

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.
