ICD-10 Code I83.0 – Varicose veins of lower extremities with ulcer (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.0 – Varicose veins of lower extremities with ulcer
What it is
I83.0 identifies varicose veins in the lower extremities when an ulcer is present. Use it for venous disease of the legs complicated by skin breakdown linked to varicosities.
Clinical signs
Typical findings include visibly enlarged, twisted leg veins with an associated lower-extremity ulcer. Clinical features vary; refer to documentation for laterality, severity, and whether the ulcer is active.
When to use this code
Use I83.0 when the provider documents varicose veins of the leg and clearly links them to an ulcer. It applies when the ulcer is part of the venous disease picture, not a separate traumatic wound. Check documentation for the exact site and any additional codes needed for ulcer depth or laterality.
Do not use for
Do not use this code for varicose veins without ulceration, or for ulcers not documented as venous/varicose in origin. Check documentation if the ulcer is from another cause.
Coding tip
Code the ulcer’s site and depth separately when the record supports it, and verify whether the vein condition is unilateral or bilateral.
