E78.81 — Lipoid dermatoarthritis
E78.81 is a billable, specific ICD-10-CM code for lipoid dermatoarthritis. It is valid for submission on a claim.
Excludes1 inherited from the categories above E78.81
These are not written on E78.81, but they bind it: a note on a category applies to every code beneath it. Billing E78.81 with anything listed here is a denial.
Other codes that can never be billed with E78.81
These codes carry an Excludes1 note pointing at E78.81. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E78.81 alone.

Risk adjustment
E78.81 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
E78.81 is named in 5 Medicare coverage policies — 5 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
