L94.0 — Localized scleroderma [morphea]
L94.0 is a billable, specific ICD-10-CM code for localized scleroderma [morphea]. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Circumscribed scleroderma
Excludes1 inherited from the categories above L94.0
These are not written on L94.0, but they bind it: a note on a category applies to every code beneath it. Billing L94.0 with anything listed here is a denial.
Other codes that can never be billed with L94.0
These codes carry an Excludes1 note pointing at L94.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L94.0 alone.
- M34Systemic sclerosis [scleroderma]
Risk adjustment
L94.0 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
L94.0 is named in 4 Medicare coverage policies — 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
