ICD-10 Code I83.811 – Varicose veins of right lower extremity with pain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.811 – Varicose veins of right lower extremity with pain
What it is
I83.811 identifies varicose veins in the right lower extremity when pain is documented. Use it for enlarged, twisted superficial veins on the right leg that are symptomatic.
Clinical signs
Typical findings include visible varicosities in the right leg with aching, heaviness, throbbing, or discomfort. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents right-sided varicose veins and specifically notes pain. It is appropriate for outpatient, inpatient, or specialty notes that link the pain to the right leg veins. If the laterality or symptom is unclear, check documentation.
Do not use for
Do not use I83.811 for varicose veins without pain, or when the affected side is not the right lower extremity. Do not assign it if documentation only says “venous insufficiency” or another venous disorder.
Coding tip
Confirm both laterality and the presence of pain in the provider note before assigning I83.811.
