ICD-10 Code for Thrombosis
Also indexed as (bland) (multiple) (progressive) (silent) (vessel)
The ICD-10-CM code for thrombosis is I82.90 — Acute embolism and thrombosis of unspecified vein. This is the code the Alphabetic Index gives for thrombosis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
BillableUnspecified
I82.90 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which thrombosis code should you use?
The Alphabetic Index lists 96 codes under Thrombosis, thrombotic. 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.
