    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.
