M30.0 — Polyarteritis nodosa
M30.0 is a billable, specific ICD-10-CM code for polyarteritis nodosa. It is valid for submission on a claim.
Other codes that can never be billed with M30.0
These codes carry an Excludes1 note pointing at M30.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M30.0 alone.
Risk adjustment
M30.0 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 94 Systemic Lupus Erythematosus and Other Specified Systemic Connective Tissue Disorders0.268 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
Medicare coverage
M30.0 is named in 29 Medicare coverage policies — 23 listing it as supporting medical necessity, and 6 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
