I46 — Cardiac arrest
Non-billable headerICD-10-CM
I46 is a non-billable header ICD-10-CM code for cardiac arrest. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- cardiogenic shock (R57.0)
Other codes that can never be billed with I46
These codes carry an Excludes1 note pointing at I46. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I46 alone.
- R09.2Respiratory arrest
Risk adjustment
I46 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 I46
3 child codes. Green means billable.
