ICD-10 Code I82.89 – Embolism and thrombosis of other specified veins (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.89 – Embolism and thrombosis of other specified veins
What it is
This code identifies a blood clot or embolus in a vein that is not named in a more specific ICD-10 category. Use it when the chart documents venous thrombosis or embolism in an “other specified” vein.
Clinical signs
Findings depend on the vein involved and may include localized pain, swelling, tenderness, or signs of impaired venous drainage. Clinical features vary; refer to documentation.
When to use this code
Use I82.89 when the provider documents embolism or thrombosis in a specified vein that does not fit a more specific code. It is appropriate when the record clearly names the vein but no dedicated ICD-10 option exists. If the documentation is vague, check documentation before assigning this code.
Do not use for
Do not use this code for superficial thrombophlebitis, deep vein thrombosis with a more specific site code, or venous embolism coded elsewhere. Check documentation if the location or vessel type is unclear.
Coding tip
Code the exact vein named in the record and verify whether a more specific I82 code applies first.
