ICD-10 Code for Vasculitis
The ICD-10-CM code for vasculitis is I77.6 — Arteritis, unspecified. This is the code the Alphabetic Index gives for vasculitis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
I77.6 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
