Summary & Overview
CPT 35180: Repair of Congenital Arteriovenous Fistula, Head and Neck
CPT code 35180 identifies surgical repair of a congenital arteriovenous fistula in the head and neck. This code captures a focused vascular surgical approach to correct abnormal arterial-to-venous connections present at birth, typically performed in an operating room or ambulatory surgical center. Nationally, accurate use of this CPT code supports appropriate clinical documentation, procedure classification, and payment for complex head and neck vascular procedures.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical indications and the typical setting for this service, plus guidance on common payer coverage expectations where available. The publication outlines benchmarks for coding and utilization, highlights relevant policy considerations that affect authorization and payment, and situates the procedure within broader vascular and head-and-neck surgical care pathways.
This summary is intended for clinicians, coding professionals, and policy analysts seeking a clear description of the code, its clinical context, and the payer landscape at a national level. Data not available in the input will be noted in the detailed sections of the full publication.
Billing Code Overview
CPT code 35180 describes a surgical procedure in which the provider makes an incision to approach a congenital arteriovenous fistula in the head and neck region and performs repair of the fistula. This procedure is a vascular surgery intervention focused on correcting abnormal connections between arteries and veins present from birth.

Clinical & Coding Specifications
Clinical Context
A typical patient is a child or young adult presenting with a congenital arteriovenous fistula (AVF) of the head or neck region causing symptoms such as a pulsatile mass, bruit, focal pain, progressive cosmetic deformity, or neurologic signs from mass effect or venous hypertension. Diagnostic workup includes history and focused head and neck exam, duplex ultrasound, CT angiography or MR angiography, and diagnostic cerebral or head/neck angiography to define feeding arteries, nidus, and venous drainage. The surgical team (often a vascular neurosurgeon, otolaryngologist, or vascular surgeon) plans an open operative approach when endovascular therapy is not feasible or as a staged hybrid with embolization.
Preoperative workflow includes consent, preop imaging review, anesthesia evaluation, and marking of the incision site. Intraoperatively, the provider makes a targeted incision to expose the AVF in the head or neck, isolates feeding vessels, and performs vessel ligation, direct repair, or resection of the fistulous segment; adjunctive microvascular techniques or intraoperative angiography may be used to confirm obliteration. Postoperative care involves neurovascular monitoring, wound care, pain control, and follow-up angiography or imaging to confirm durable obliteration and assess for recurrence. Typical length of stay varies from same-day observation for select minor exposures to several days for complex repairs with monitoring.
