ICD-10 Code I83.004 – Varicose veins of unspecified lower extremity with ulcer of heel and midfoot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.004 – Varicose veins of unspecified lower extremity with ulcer of heel and midfoot
What it is
This code identifies varicose veins in an unspecified lower extremity when a venous ulcer is present on the heel or midfoot. Use it when the documentation links the ulcer to varicose vein disease.
Clinical signs
Typical findings include visibly enlarged, twisted superficial leg veins and a chronic ulcer over the heel or midfoot. Clinical features vary; refer to documentation for laterality, ulcer depth, and whether the ulcer is active.
When to use this code
Use I83.004 when the provider documents varicose veins of the leg with a venous ulcer specifically located on the heel or midfoot. It fits cases where the lower extremity is not specified as left or right. If the record does not clearly connect the ulcer to varicose veins, check documentation.
Do not use for
Do not use this code for ulcers at other foot sites, such as the ankle or calf, or when the ulcer cause is not venous. Do not assume laterality; if the documentation specifies left or right, code that instead.
Coding tip
Verify both the ulcer location and the venous cause before assigning I83.004.
