D22.9 — Melanocytic nevi, unspecified
D22.9 is a billable, specific ICD-10-CM code for melanocytic nevi, unspecified. It is valid for submission on a claim.
Other codes that can never be billed with D22.9
These codes carry an Excludes1 note pointing at D22.9. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D22.9 alone.
- I78.1Nevus, non-neoplastic
Risk adjustment
D22.9 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
D22.9 is named in 11 Medicare coverage policies — 11 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
