ICD-10 Code I83.81 – Varicose veins of lower extremities with pain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.81 – Varicose veins of lower extremities with pain
What it is
I83.81 identifies varicose veins in the lower extremities when pain is documented. Use it for dilated, twisted superficial leg veins associated with discomfort rather than cosmetic concern alone.
Clinical signs
Typical findings include visible enlarged leg veins and reported aching, heaviness, throbbing, or soreness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents varicose veins of the legs and specifically links them to pain. It is appropriate for office, vascular, or outpatient notes describing symptomatic lower-extremity varicosities. If pain is not documented, check documentation before assigning this code.
Do not use for
Do not use it for asymptomatic varicose veins or for venous disorders without documented pain. Check documentation if the note instead describes edema, ulceration, inflammation, or another venous condition.
Coding tip
Confirm that pain is explicitly associated with the varicose veins before coding I83.81.
