ICD-10 Code I83.018 – Varicose veins of right lower extremity with ulcer other part of lower leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.018 – Varicose veins of right lower extremity with ulcer other part of lower leg
What it is
This code identifies varicose veins in the right leg when an ulcer is present on another part of the lower leg, not the ankle or foot. It reflects chronic venous disease with skin breakdown.
Clinical signs
Typical findings include visible tortuous veins, leg heaviness, swelling, and a venous ulcer on the lower leg. Clinical features vary; refer to documentation for ulcer location and laterality.
When to use this code
Use I83.018 when the provider documents varicose veins of the right lower extremity and specifies an ulcer on the lower leg. The ulcer location should be documented as other part of lower leg, not ankle or foot. If the record does not clearly identify the site, check documentation.
Do not use for
Do not use this code for left-leg disease, bilateral varicose veins, or varicose veins without ulceration. Do not assign it when the ulcer site is ankle, foot, or another condition is documented instead.
Coding tip
Confirm both laterality and ulcer location in the note before coding, because these details drive the correct I83.018 selection.
