L87.1 — Reactive perforating collagenosis

Other codes that can never be billed with L87.1
These codes carry an Excludes1 note pointing at L87.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L87.1 alone.
- M35Other systemic involvement of connective tissue
Risk adjustment
L87.1 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
L87.1 is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
