ICD-10 Code I83.023 – Varicose veins of left lower extremity with ulcer of ankle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.023 – Varicose veins of left lower extremity with ulcer of ankle
What it is
This code identifies varicose veins in the left leg when an ulcer is present at the ankle. Use it when documentation links the ulcer to the varicose vein disease.
Clinical signs
Typical findings include visibly enlarged, tortuous superficial veins and a chronic ulcer near the left ankle. Clinical features vary; refer to documentation for laterality, ulcer location, and whether the ulcer is venous in origin.
When to use this code
Use I83.023 when the record states varicose veins of the left lower extremity with an ankle ulcer, or clearly documents a venous stasis ulcer at that site. You should code the condition only when the ulcer and varicose veins are both documented together.
If the note identifies a different leg, a different ulcer location, or a different cause of ulceration, choose the more accurate code. Check documentation for laterality and the exact relationship between the ulcer and the varicose veins.
Do not use for
Do not use this code for varicose veins without an ulcer, or for ulcers caused by another disease process. Do not assume laterality or ankle involvement if the chart does not support it.
Coding tip
Verify the left-sided location and ankle ulcer in the provider note before assigning this code.
