Other codes that can never be billed with D86.85
These codes carry an Excludes1 note pointing at D86.85. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D86.85 alone.
Risk adjustment
D86.85 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
D86.85 is named in 28 Medicare coverage policies — 28 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
