Non-billable headerICD-10-CM

Other codes that can never be billed with F12.1
These codes carry an Excludes1 note pointing at F12.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F12.1 alone.
Risk adjustment
F12.1 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.
