Other codes that can never be billed with O75.1

These codes carry an Excludes1 note pointing at O75.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O75.1 alone.

Risk adjustment

O75.1 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.

Medicare coverage

O75.1 is named in 2 Medicare coverage policies 2 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
