Other codes that can never be billed with A01.0
These codes carry an Excludes1 note pointing at A01.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A01.0 alone.
Risk adjustment
A01.0 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.
