ICD-10 Code for Thrombosis

The default ICD-10-CM 2027 code for thrombosis, thrombotic (bland) (multiple) (progressive) (silent) (vessel) is I82.90 – Acute embolism and thrombosis of unspecified vein. More specific codes depend on the details documented, as listed in the official index (96 codes, 53 billable).

How to choose the right code

Start with the main term, then pick the indented subterm that matches the documentation (type, cause, site, laterality, episode of care). Always confirm the code in the tabular list: follow its Excludes1/Excludes2, “code first” and “use additional code” notes, and add a 7th character where required.
