I82.50

Chronic embolism and thrombosis of unspecified deep veins of lower extremity

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 4 more specific codes instead:

  • I82.501 Chronic embolism and thrombosis of unspecified deep veins of right lower extremity
  • I82.502 Chronic embolism and thrombosis of unspecified deep veins of left lower extremity
  • I82.503 Chronic embolism and thrombosis of unspecified deep veins of lower extremity, bilateral
  • I82.509 Chronic embolism and thrombosis of unspecified deep veins of unspecified lower extremity

What has happened to this code

Every change the publisher made, from 2010 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

  1. FY2010 Added to the draft code set draft Chronic embolism and thrombosis of unspecified deep veins of lower extremity
  2. FY2011 Removed from the draft draft
  3. FY2012 Returned to the draft draft

Official coding rules
