ICD-10 Code for Arteriopathy
The ICD-10-CM code for arteriopathy is I77.9 — Disorder of arteries and arterioles, unspecified. This is the code the Alphabetic Index gives for arteriopathy with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
I77.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
