ICD-10 Code I83.025 – Varicose veins of left lower extremity with ulcer other part of foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.025 – Varicose veins of left lower extremity with ulcer other part of foot
What it is
This code identifies varicose veins in the left leg when an ulcer is present on another part of the foot. Use it for chronic venous disease with a documented ulcer location on the left lower extremity.
Clinical signs
Typical findings include enlarged, tortuous superficial veins and a venous ulcer on the foot. Clinical features vary; refer to documentation for ulcer site, laterality, and whether the ulcer is associated with venous insufficiency.
When to use this code
Use I83.025 when the provider documents varicose veins of the left lower extremity and specifically links them to an ulcer on another part of the foot. The record should support both the venous disease and the ulcer location. If the ulcer site or laterality is unclear, check documentation before coding.
Do not use for
Do not use this code for varicose veins without an ulcer, or for ulcers not documented as venous. It is also incorrect when the ulcer is on a different body site or the left-sided varicose vein diagnosis is not confirmed.
Coding tip
Confirm the ulcer’s exact location and that the venous cause is documented before assigning I83.025.
