Medical Necessity of CPT Code 36465 for Bilateral Anterior Accessory Saphenous Vein Treatment

Patient Assessment and Criteria Met

A 62-year-old female patient with incompetent bilateral anterior accessory saphenous veins (AASVs) presents with symptoms that significantly interfere with activities of daily living, which are clear indications for intervention beyond conservative management 1
Ultrasound demonstrates incompetent bilateral anterior accessory saphenous veins with reflux times exceeding the minimum threshold of 500ms required for treatment 1
Vein diameters exceed the minimum requirement of 2.5mm for sclerotherapy treatment 1
The patient has failed conservative management including medical grade compression therapy for >6 months, daily leg elevation, exercise, and analgesics 1
Patient has CEAP Class 3 (edema) in one leg and CEAP Class 4a (pigmentation or eczema) in the other leg, indicating moderate-to-severe venous disease requiring intervention 1

Duplex ultrasound confirms bilateral AASV incompetence with reflux times >500ms, according to the American College of Radiology 2, 1
CEAP classifications of C3 and C4a indicate moderate-to-severe venous disease 1
The American College of Radiology recommends foam sclerotherapy, including Varithena, as an appropriate treatment for tributary veins or as an adjunct to primary treatment of the saphenofemoral junction 1
Foam sclerotherapy has documented occlusion rates of 72-89% at 1 year for treatment of varicose veins 1
For patients who have already undergone treatment of the main saphenous trunks, sclerotherapy is indicated for persistent symptomatic accessory veins 1

The treatment of both legs is appropriate given the documented bilateral incompetence and symptoms, according to the medical necessity criteria 1
