Summary & Overview
CPT 37609: Temporal Artery Ligation for Aneurysm Treatment
CPT code 37609 denotes surgical ligation of the temporal artery, often performed to treat a temporal artery aneurysm and sometimes accompanied by a biopsy. This code captures a targeted vascular surgical intervention and is relevant to vascular surgeons, otolaryngologists, and surgical centers. Nationally, accurate coding of this procedure affects claims adjudication, facility and professional payment, and clinical documentation at hospitals and ambulatory surgical centers.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, common billing considerations, and the service and site settings associated with the code. The publication summarizes benchmarks and payment considerations where available and highlights policy or coding guidance relevant to facility and professional reporting.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents with a pulsatile, tender temporal mass and localized pain over the superficial temporal artery consistent with a temporal artery aneurysm. After clinical evaluation and duplex ultrasound confirming a confined aneurysmal dilation of the superficial temporal (temporal) artery, the vascular or head and neck surgical team schedules a focused outpatient operative procedure. In the preoperative workflow the surgeon reviews anticoagulation, obtains informed consent including discussion of possible biopsy, and coordinates anesthesia (local with monitored anesthesia care or general if required). Intraoperatively the provider makes an incision anterior to the ear to identify and isolate the temporal artery, then ligates the artery proximally and distally with suture or clamp and excises the aneurysmal segment as indicated; an optional arterial biopsy may be taken for histopathology. Hemostasis is confirmed, wound is closed, and the patient is monitored in a post-anesthesia recovery area with discharge instructions for wound care and activity restrictions. Typical sites of service are an ambulatory surgery center (ASC) or hospital outpatient surgical department. Common clinical team members include a vascular surgeon, otolaryngologist or general surgeon, a circulating nurse, scrub tech, and anesthesia provider when indicated.
