ICD-10 Code for Angiopathia
The ICD-10-CM code for angiopathia is I99.9 — Unspecified disorder of circulatory system. This is the code the Alphabetic Index gives for angiopathia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
I99.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which angiopathia code should you use?
The Alphabetic Index lists 7 codes under Angiopathia, angiopathy. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
By type
