ICD-10 Code I83.11 – Varicose veins of right lower extremity with inflammation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.11 – Varicose veins of right lower extremity with inflammation
What it is
This code identifies varicose veins in the right lower leg or thigh when the veins are inflamed. Use it when documentation clearly states both the right-sided location and inflammation.
Clinical signs
Typical findings include visibly enlarged, twisted superficial veins with localized tenderness, redness, or swelling. Clinical features vary; refer to documentation for the specific inflammatory findings.
When to use this code
Use I83.11 when the provider documents varicose veins of the right lower extremity with phlebitis or inflammation. It fits outpatient, inpatient, and specialty notes when the diagnosis is explicitly stated.
If the record only says varicose veins without inflammation, choose a different code. Confirm laterality carefully, because right lower extremity is required for this code.
Do not use for
Do not use this code for uncomplicated varicose veins, left-sided disease, or bilateral disease. Check documentation if the note does not clearly mention inflammation.
Coding tip
Verify both the side and the inflammatory component before assigning I83.11.
