ICD-10 Code I82.29 – Embolism and thrombosis of other thoracic veins (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.29 – Embolism and thrombosis of other thoracic veins
What it is
I82.29 identifies a blood clot or blockage in a thoracic vein other than the major named chest veins. Use it when documentation specifies an embolism or thrombosis in an “other thoracic vein.”
Clinical signs
Clinical features vary; refer to documentation. You may see chest venous obstruction, localized swelling, pain, or collateral vein development, but the diagnosis must be supported by a documented thoracic venous clot.
When to use this code
Use this code when the provider documents embolism or thrombosis involving a thoracic vein not captured by a more specific code. It is appropriate for confirmed chest venous thrombosis, including imaging-supported findings, when the site is clearly thoracic and otherwise unspecified.
Do not use for
Do not use I82.29 for lower-extremity, upper-extremity, portal, or intracranial venous thrombosis. If the note names a more specific thoracic vein or another vascular territory, code that documented site instead.
Coding tip
Check the exact vein named in the record; if the thoracic location is vague, query for clarification before coding.
