ICD-10 Code I82.290 – Acute embolism and thrombosis of other thoracic veins (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.290 – Acute embolism and thrombosis of other thoracic veins
What it is
I82.290 identifies an acute blood clot or embolus in a thoracic vein not named elsewhere in the code set. Use it when the documentation specifies an acute thrombotic or embolic event in an “other” thoracic vein.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe venous obstruction findings such as localized pain, swelling, venous distention, or imaging confirmation of an acute clot.
When to use this code
Use this code when the provider documents acute embolism or thrombosis involving a thoracic vein outside the specifically listed thoracic sites. It is appropriate when imaging, operative notes, or discharge summaries clearly identify the vein and the acute nature of the event. Check documentation if the vessel is not named.
Do not use for
Do not use it for chronic, old, or resolved thrombosis, or when the clot is in a different venous territory. If the record names a more specific thoracic vein code, choose that code instead.
Coding tip
Verify both acuity and the exact thoracic vein before assigning I82.290.
