ICD-10 Code I82.890 – Acute embolism and thrombosis of other specified veins (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.890 – Acute embolism and thrombosis of other specified veins
What it is
This code identifies an acute blood clot or embolus in a specified vein that is not named elsewhere in ICD-10-CM. Use it when documentation clearly states an acute venous thrombosis in another specified vein.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see localized swelling, pain, tenderness, or signs of venous obstruction in the affected area.
When to use this code
Use I82.890 when the provider documents acute embolism or thrombosis in a specific vein that does not have a more exact ICD-10-CM code. It is appropriate when the record identifies the vein involved and the condition is acute. Check documentation if the site is vague or if chronic thrombosis is described instead.
Do not use for
Do not use this code for chronic venous thrombosis, superficial thrombophlebitis, or DVT with a more specific site code. If the vein or acuity is not documented, check documentation.
Coding tip
Verify the exact vein named in the note before assigning I82.890.
