ICD-10 Code I82.8 – Embolism and thrombosis of other specified veins (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.8 – Embolism and thrombosis of other specified veins
What it is
This code identifies a clot or embolus in a vein that is not named in a more specific ICD-10 category. Use it when the record clearly documents venous thrombosis or embolism, but the vein involved is described as “other specified.”
Clinical signs
Clinical features vary; refer to documentation. Common findings may include localized swelling, pain, tenderness, or signs of venous obstruction, and imaging or specialist notes may confirm the affected vein.
When to use this code
Use I82.8 when the provider documents embolism or thrombosis in a specified vein that does not fit a more precise code. It is appropriate when the anatomic site is named, but no dedicated code exists for that vessel. Check the note for acute, chronic, or recurrent descriptors if they affect code selection.
Do not use for
Do not use this code for thrombosis in veins with a more specific ICD-10 option, or when the record only states superficial thrombophlebitis or an unspecified clot. Check documentation.
Coding tip
Code the most specific vein named in the chart and verify whether the provider documents embolism, thrombosis, or both.
