ICD-10 Code I83.91 – Asymptomatic varicose veins of right lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.91 – Asymptomatic varicose veins of right lower extremity
What it is
I83.91 identifies varicose veins in the right lower extremity when no symptoms are documented. Use it for visible, enlarged superficial veins on the right leg without pain, swelling, or other stated complaints.
Clinical signs
Typical findings include dilated, tortuous superficial veins on the right leg. Clinical features vary; refer to documentation, and confirm that the record states the condition is asymptomatic.
When to use this code
Use this code when the provider documents varicose veins limited to the right lower extremity and explicitly notes no symptoms. It also fits routine encounters where the diagnosis is recorded without associated pain, edema, skin changes, or ulceration. If symptoms are present, check documentation for a more specific code.
Do not use for
Do not use I83.91 if the varicose veins are symptomatic, bilateral, or documented in another lower-extremity location. Check documentation if the note mentions complications such as inflammation, ulceration, or other venous disease.
Coding tip
Verify laterality and the word “asymptomatic” in the provider note before assigning I83.91.
