T41 — Poisoning by, adverse effect of and underdosing of anesthetics and therapeutic gases
T41 is a non-billable header ICD-10-CM code for poisoning by, adverse effect of and underdosing of anesthetics and therapeutic gases. 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 T41
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Other codes that can never be billed with T41
These codes carry an Excludes1 note pointing at T41. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T41 alone.
Risk adjustment
T41 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.
