T41.1 — Poisoning by, adverse effect of and underdosing of intravenous anesthetics
T41.1 is a non-billable header ICD-10-CM code for poisoning by, adverse effect of and underdosing of intravenous anesthetics. 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.

Other codes that can never be billed with T41.1
These codes carry an Excludes1 note pointing at T41.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T41.1 alone.
- T42.3Poisoning by, adverse effect of and underdosing of barbiturates
Risk adjustment
T41.1 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 T41.1
