ICD-10 Code for Arteriosclerosis
Also indexed as (diffuse) (obliterans) (of) (senile) (with calcification)
The ICD-10-CM code for arteriosclerosis is I70.90 — Unspecified atherosclerosis. This is the code the Alphabetic Index gives for arteriosclerosis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
BillableUnspecified
I70.90 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which arteriosclerosis code should you use?
The Alphabetic Index lists 298 codes under Arteriosclerosis, arteriosclerotic. 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.
