ICD-10 Code for Embolism

Also indexed as (multiple) (paradoxical)

The ICD-10-CM code for embolism is I74.9 — Embolism and thrombosis of unspecified artery. This is the code the Alphabetic Index gives for embolism with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).

BillableUnspecified

I74.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.

Which embolism code should you use?

The Alphabetic Index lists 125 codes under Embolism. 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.
