ICD-10 Code I82.2 – Embolism and thrombosis of vena cava and other thoracic veins (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.2 – Embolism and thrombosis of vena cava and other thoracic veins
What it is
I82.2 identifies a blood clot or embolus in the vena cava or other thoracic veins. Use it when documentation specifies thrombosis or embolism in these central chest veins.
Clinical signs
Clinical features vary; refer to documentation. Findings may include venous obstruction or imaging-confirmed clot in the vena cava or thoracic veins, with symptoms depending on location and extent.
When to use this code
Use this code when the provider documents embolism or thrombosis involving the vena cava or another thoracic vein. It may be supported by imaging, operative findings, or a clear assessment in the record. Check documentation if the vein involved is not specifically identified.
Do not use for
Do not use I82.2 for thrombosis in lower-extremity, upper-extremity, portal, or cerebral veins. If the record only says “DVT” without thoracic vein involvement, choose the more specific documented site.
Coding tip
Code the exact vein named in the documentation and verify whether the condition is embolism, thrombosis, or both.
