ICD-10 Code I83.813 – Varicose veins of bilateral lower extremities with pain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.813 – Varicose veins of bilateral lower extremities with pain
What it is
I83.813 identifies varicose veins affecting both lower extremities when pain is documented. Use it for dilated, twisted superficial veins in both legs that are symptomatic.
Clinical signs
Typical findings include visible or palpable enlarged superficial veins, leg discomfort, aching, heaviness, or localized tenderness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bilateral lower-extremity varicose veins and specifically notes pain. It applies when pain is part of the diagnosis, not just an incidental complaint. If laterality or symptom detail is unclear, check documentation before coding.
Do not use for
Do not use I83.813 for varicose veins without pain, for unilateral disease, or when the record only describes venous insufficiency. Check documentation.
Coding tip
Confirm both laterality and the symptom of pain in the note before assigning I83.813.
