Summary & Overview
CPT 37760: Ligation and Excision of Perforator Vein for Varicose Veins
CPT code 37760 represents open surgical ligation and excision of perforator veins in one leg to treat varicose vein disease. Nationally, this code captures a specific invasive venous procedure used when perforator incompetence requires direct surgical correction rather than solely endovenous or conservative therapies. Its use has implications for surgical capacity, site-of-service decision-making, and payer coverage policies for venous surgery.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a clinical and billing orientation to the procedure, typical sites of service, and the reasons this code matters for claim adjudication and benefit design. The publication covers utilization benchmarks, common coding and billing considerations, and recent policy developments affecting surgical venous care where available.
The report provides clinicians, billing staff, and policy analysts with actionable context: how 37760 fits into the spectrum of varicose vein treatments, what documentation and procedural descriptors are central to correct coding, and how major payers approach coverage and site-of-service considerations. Data not available in the input will be identified where applicable.
Billing Code Overview
CPT code 37760 describes an open surgical procedure to ligate and excise incompetent perforator veins of the lower extremity to treat varicose veins in a single leg. The procedure involves incisions along the affected superficial vein, dissection through the fascia to access the targeted perforator vein, excision of adjacent diseased structures, ligation of the perforator vein, and may include placement of a skin graft to cover the excision site.
Service type: Surgical, venous surgery for varicose veins
Typical site of service: Hospital outpatient surgery center or inpatient operating room, with potential follow-up care in ambulatory or clinic settings
Clinical & Coding Specifications
Clinical Context
A 58-year-old ambulatory female presents to a vascular surgery clinic with symptomatic varicose veins of the right lower extremity characterized by aching, edema, recurrent superficial thrombophlebitis, and skin changes overlying incompetent perforator veins. Noninvasive duplex ultrasound confirms one or more incompetent perforator veins connecting the superficial venous system to the deep system with reflux. Conservative therapy (compression, leg elevation) has failed to relieve symptoms. The provider plans an open perforator vein ligation and excision of adjacent diseased tissue with possible placement of a small split-thickness skin graft at the excision site, performed under regional or general anesthesia.
Preoperative workflow includes history and physical, venous duplex mapping, informed consent documenting risks/benefits and alternatives, and anesthesia evaluation. Intraoperative steps include marking the targeted perforator(s), making incisions over the affected vein, incising through fascia to access and ligate the perforator, excising diseased subcutaneous tissue as indicated, achieving hemostasis, and placing a skin graft if the defect requires coverage. Postoperative care includes wound care instructions, compression therapy, activity limitations, and follow-up duplex as clinically indicated.
