Other codes that can never be billed with A49.02
These codes carry an Excludes1 note pointing at A49.02. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A49.02 alone.
- Z16Resistance to antimicrobial drugs
Risk adjustment
A49.02 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.
