ICD-10 Code I83.9 – Asymptomatic varicose veins of lower extremities (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.9 – Asymptomatic varicose veins of lower extremities
What it is
I83.9 identifies varicose veins in the lower extremities when the condition is present but no symptoms are documented. Use it for visible, dilated superficial leg veins without pain, swelling, or other reported complaints.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record notes tortuous or enlarged superficial veins in one or both legs, with no associated symptoms or complications described.
When to use this code
Use this code when the provider documents asymptomatic varicose veins of the lower extremities and does not specify inflammation, ulceration, or other complications. It also fits when the veins are noted on exam or imaging and the chart states no symptoms.
If the note describes pain, swelling, skin changes, or venous ulceration, you should not default to this code. Check documentation for laterality, severity, or any complication that requires a more specific code.
Do not use for
Do not use I83.9 for symptomatic varicose veins, superficial thrombophlebitis, venous ulcers, or other documented complications. Check documentation if the provider records a different venous disorder.
Coding tip
Code I83.9 only when the record clearly states the varicose veins are asymptomatic and uncomplicated.
