2026 ICD-10-CM Diagnosis Code I83.201 – Varicose veins of unspecified lower extremity with both ulcer of thigh and inflammation
What it is
This code identifies varicose veins in an unspecified lower extremity when the condition is complicated by a thigh ulcer and inflammation. Use it when documentation links the venous disease to both ulceration and inflammatory changes.
Clinical signs
Typical findings include visible varicosities, localized swelling, skin irritation, and an ulcer on the thigh with signs of inflammation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states varicose veins of an unspecified leg plus both an ulcer of the thigh and inflammation. It fits encounters where the ulcer and inflammatory changes are documented as part of the venous disorder. If the laterality or ulcer site is specified differently, code to the documented details.
Do not use for
Do not use it for uncomplicated varicose veins, ulcers without venous disease, or inflammation that is not documented as related to the varicosities. Check documentation.
Coding tip
Confirm that the ulcer location is the thigh and that both ulcer and inflammation are present before assigning I83.201.
