ICD-10 Code I83.013 – Varicose veins of right lower extremity with ulcer of ankle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.013 – Varicose veins of right lower extremity with ulcer of ankle
What it is
This code identifies varicose veins in the right leg when an ulcer is present at the ankle. It combines the venous disorder with the location of the ulcer, so you should confirm both in the record.
Clinical signs
Typical findings include visible, enlarged superficial veins and a chronic ulcer around the right ankle. Clinical features vary; refer to documentation for laterality, ulcer location, and whether the ulcer is linked to venous disease.
When to use this code
Use I83.013 when the provider documents varicose veins of the right lower extremity and an associated ankle ulcer. This is appropriate when the ulcer is described as venous or clearly tied to the varicose veins. If the ulcer site or laterality is not stated, check documentation before coding.
Do not use for
Do not use this code for varicose veins without an ulcer, or for ulcers of another cause. If the ulcer is on a different leg or a different part of the lower extremity, choose the matching code.
Coding tip
Capture both laterality and ulcer location exactly as documented, because the code depends on both details.
