ICD-10 Code I83.002 – Varicose veins of unspecified lower extremity with ulcer of calf (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.002 – Varicose veins of unspecified lower extremity with ulcer of calf
What it is
This code identifies varicose veins in an unspecified lower extremity when an ulcer is present on the calf. It combines the venous disorder with the location of the ulcer.
Clinical signs
Typical findings include visibly enlarged, tortuous leg veins and a chronic skin ulcer on the calf. Clinical features vary; refer to documentation for laterality and ulcer details.
When to use this code
Use I83.002 when the provider documents varicose veins affecting a lower extremity and specifies a calf ulcer, but does not identify the side. The record should support both the venous disease and the ulcer location. If laterality is documented, choose a more specific code.
Do not use for
Do not use this code for varicose veins without an ulcer, or for ulcers of the foot, ankle, or other sites. Check documentation if the ulcer is due to a different cause.
Coding tip
Verify that the ulcer is documented as being on the calf and that laterality is truly unspecified before assigning this code.
