T44.4 — Poisoning by, adverse effect of and underdosing of predominantly alpha-adrenoreceptor agonists
T44.4 is a non-billable header ICD-10-CM code for poisoning by, adverse effect of and underdosing of predominantly alpha-adrenoreceptor agonists. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.
This code requires a 7th character
The appropriate 7th character is to be added to each code from category T44
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Poisoning by, adverse effect of and underdosing of metaraminol
Other codes that can never be billed with T44.4
These codes carry an Excludes1 note pointing at T44.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T44.4 alone.
- T46Poisoning by, adverse effect of and underdosing of agents primarily affecting the cardiovascular system
Risk adjustment
T44.4 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code to one of these instead T44.4
1 child code. Green means billable.
