ICD-10 Code I83.21 – Varicose veins of right lower extremity with both ulcer and inflammation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.21 – Varicose veins of right lower extremity with both ulcer and inflammation
What it is
This code identifies varicose veins in the right leg complicated by both an ulcer and inflammation. Use it when documentation clearly links the ulcer and inflammatory changes to the varicose veins.
Clinical signs
Typical findings include visible dilated superficial veins with skin breakdown and local inflammatory changes such as redness, swelling, or tenderness. Clinical features vary; refer to documentation.
When to use this code
Use I83.21 when the provider documents varicose veins of the right lower extremity with both ulceration and inflammation. The record should show that both complications are present on the right side and associated with the varicose veins.
Choose this code when the note specifies the ulcer and inflammatory process rather than describing uncomplicated varicose veins. If the laterality or complication is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for uncomplicated varicose veins, left-sided disease, or varicose veins with only ulcer or only inflammation. Check documentation if the site or complication is not clearly stated.
Coding tip
Confirm right-sided laterality and both complications in the provider note before coding.
