ICD-10 Code I83.02 – Varicose veins of left lower extremity with ulcer (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.02 – Varicose veins of left lower extremity with ulcer
What it is
This code identifies varicose veins in the left lower extremity that are complicated by an ulcer. Use it when the record links the ulcer to venous disease in the left leg.
Clinical signs
Typical findings include visibly enlarged, twisted leg veins with a chronic skin ulcer on the left lower extremity. Clinical features vary; refer to documentation for venous stasis changes or ulcer location.
When to use this code
Use I83.02 when the provider documents varicose veins of the left leg and an associated ulcer. The note should support that the ulcer is part of the venous disease, not due to trauma, diabetes, or another cause. Check documentation if laterality or ulcer relationship is unclear.
Do not use for
Do not use this code for varicose veins without ulceration, or for ulcers from a different etiology. If the record does not specify the left lower extremity, verify the laterality before coding.
Coding tip
Confirm both the left-sided varicose veins and the ulcer linkage in the provider note before assigning I83.02.
