ICD-10 Code I83.029 – Varicose veins of left lower extremity with ulcer of unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.029 – Varicose veins of left lower extremity with ulcer of unspecified site
What it is
This code identifies varicose veins in the left leg when an ulcer is present, but the ulcer location is not specified. Use it for chronic venous disease documented on the left lower extremity with an associated ulcer.
Clinical signs
Typical findings include visible, enlarged, twisted superficial veins in the left lower leg and an open skin ulcer related to venous insufficiency. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states varicose veins of the left lower extremity and also documents an ulcer, but does not identify the ulcer site more specifically. It is appropriate when the provider links the ulcer to the varicose veins. Check documentation if laterality or ulcer details are unclear.
Do not use for
Do not use this code for right or bilateral leg disease, or when varicose veins are present without an ulcer. If the ulcer is documented at a specific site, confirm whether a more precise code applies.
Coding tip
Verify laterality and whether the ulcer is explicitly associated with the varicose veins before assigning I83.029.
