ICD-10 Code I82.719 – Chronic embolism and thrombosis of superficial veins of unspecified upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.719 – Chronic embolism and thrombosis of superficial veins of unspecified upper extremity
What it is
This code identifies a chronic clot or embolic blockage in a superficial vein of the upper extremity when the affected side is not specified. Use it for long-standing venous obstruction in arm or hand superficial veins.
Clinical signs
Findings may include localized swelling, tenderness, cordlike vein changes, or persistent discomfort in the arm. Clinical features vary; refer to documentation for evidence of chronic superficial venous thrombosis or embolism.
When to use this code
Use I82.719 when the record clearly documents chronic embolism or thrombosis involving a superficial vein in the upper extremity, but laterality is not stated. It may apply to follow-up encounters where the condition remains active or is still being monitored. If the note only says “upper extremity superficial thrombosis,” check documentation for chronicity.
Do not use for
Do not use this code for acute thrombosis, deep vein thrombosis, or superficial vein disease of the lower extremity. If the side is documented, select the specified upper-extremity code instead.
Coding tip
Confirm both chronicity and site in the chart; if either is missing, you should query or check documentation before assigning I82.719.
