Summary & Overview
CPT 76706: Ultrasound of Abdominal Aorta for Aneurysm Screening
CPT code 76706 represents an ultrasound examination of the abdominal aorta used primarily to screen for or evaluate an abdominal aortic aneurysm (AAA). As a focused vascular imaging procedure, it is important for early detection of aneurysmal dilation, which can prevent life‑threatening rupture when identified and managed. Nationally, this procedure is commonly performed in outpatient imaging centers, hospital outpatient departments, and ambulatory clinics and is part of preventive and diagnostic vascular care pathways.
Key payers included in the coverage discussion are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for AAA screening and diagnostic use, typical sites of service, and the types of benchmarks and policy considerations that commonly accompany vascular ultrasound billing. The publication summarizes reimbursement benchmarks where available, highlights common documentation and coding considerations tied to vascular imaging, and outlines potential policy updates or payer practice trends that affect access and payment for abdominal aorta ultrasound services.
This summary is targeted to coding professionals, practice managers, and policy analysts seeking a concise national overview of the clinical purpose and payer landscape for CPT code 76706 and what to expect in detailed sections covering benchmarks, coverage nuances, and clinical context.
Billing Code Overview
CPT code 76706 describes a noninvasive ultrasound of the abdominal aorta performed to screen for an abdominal aortic aneurysm (AAA) — a focal dilation or weakening of the aortic wall that can lead to rupture if undetected. The procedure uses high‑frequency sound waves to create images of the abdominal aorta and assess its size and contour.
Service Type: Screening/Diagnostic Ultrasound
Typical Site of Service: Outpatient imaging center, hospital outpatient department, or clinic

Clinical & Coding Specifications
Clinical Context
A 68-year-old male with a history of smoking and hypertension is seen in the vascular lab for screening for an abdominal aortic aneurysm (AAA). The patient reports no abdominal pain but has risk factors including male sex, age over 65, and prior tobacco use. The clinical workflow begins with a referral from the primary care provider or vascular specialist. The patient arrives at an outpatient vascular ultrasound facility or hospital radiology department. The sonographer documents history, explains the procedure risks and benefits, and performs a focused transabdominal ultrasound of the abdominal aorta from the diaphragmatic hiatus to the iliac bifurcation, obtaining transverse and longitudinal measurements, documenting maximal anterior–posterior diameter, and saving images. A interpreting physician (radiologist, vascular surgeon, or cardiologist) reviews the images, provides a formal report noting aorta size, presence of aneurysm or thrombus, and recommendations for surveillance or referral. Results are communicated to the referring clinician for follow-up management.
