2026 ICD-10-CM Diagnosis Code I83.221 – Varicose veins of left lower extremity with both ulcer of thigh and inflammation
What it is
This code identifies varicose veins in the left leg with an ulcer located on the thigh and signs of inflammation. Use it when the record clearly links the ulcer and inflammatory changes to the varicose veins.
Clinical signs
Typical findings include visibly enlarged, twisted superficial veins and a skin ulcer on the left thigh. Documentation may also note local inflammation such as redness, swelling, or tenderness; clinical features vary, refer to documentation.
When to use this code
Use I83.221 when the provider documents varicose veins of the left lower extremity plus both ulceration and inflammation at the thigh site. The diagnosis should specify laterality and the ulcer location. If the note is unclear, check documentation before coding.
Do not use for
Do not use this code for varicose veins without an ulcer or without inflammation. It is also incorrect if the ulcer is on a different site or if the condition is documented on the right leg or both legs.
Coding tip
Verify that laterality, ulcer site, and inflammation are all documented together before assigning this code.
