ICD-10 Code I83.90 – Asymptomatic varicose veins of unspecified lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.90 – Asymptomatic varicose veins of unspecified lower extremity
What it is
This code identifies varicose veins in a lower extremity when the record does not specify the leg and the patient has no symptoms. It reflects visible or documented venous dilation without pain, swelling, or other reported complaints.
Clinical signs
Typical findings include enlarged, tortuous superficial veins on the leg. Clinical features vary; refer to documentation, and use this code only when the record states the veins are asymptomatic.
When to use this code
Use I83.90 when the provider documents asymptomatic varicose veins of a lower limb but does not identify right or left. It also fits routine encounters where the finding is noted incidentally and no venous symptoms are recorded. Check documentation if laterality or complications are mentioned.
Do not use for
Do not use this code for symptomatic varicose veins, such as those with pain, edema, or skin changes. Also avoid it when the affected leg is specified and a more exact laterality code is available.
Coding tip
Look for laterality and any documented symptoms before assigning I83.90.
