R23.8 — Other skin changes
R23.8 is a billable, specific ICD-10-CM code for other skin changes. It is valid for submission on a claim.
Other codes that can never be billed with R23.8
These codes carry an Excludes1 note pointing at R23.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R23.8 alone.
- R21Rash and other nonspecific skin eruption
Risk adjustment
R23.8 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
R23.8 is named in 6 Medicare coverage policies — 6 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
