ICD-10 Code I83.20 – Varicose veins of unspecified lower extremity with both ulcer and inflammation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.20 – Varicose veins of unspecified lower extremity with both ulcer and inflammation
What it is
This code identifies varicose veins in an unspecified lower extremity when both an ulcer and inflammation are documented. Use it when the record confirms the vein disease and the skin complication.
Clinical signs
Typical findings include visibly enlarged, tortuous leg veins with localized ulceration and inflammatory changes such as redness or tenderness. Clinical features vary; refer to documentation.
When to use this code
Use I83.20 when the provider documents varicose veins of a lower extremity plus both ulcer and inflammation, but does not specify left or right side. It fits outpatient, inpatient, or consult notes that clearly link the ulcer and inflammation to the varicose veins. Check documentation if laterality or severity is stated elsewhere.
Do not use for
Do not use this code if only varicose veins are documented without ulcer and inflammation. Also avoid it when the affected leg is specified and a more exact laterality code applies.
Coding tip
Verify that the ulcer and inflammation are both attributed to the varicose veins before assigning I83.20.
