CPT® Code 75625

Abdominal aortography by serialography is a specialized vascular imaging procedure designed to evaluate the structural integrity of the aorta and assess blood flow dynamics within this major blood vessel. The procedure begins with the insertion of a large bore needle into a blood vessel located in the groin area, which serves as the access point for further instrumentation. A guidewire is then carefully introduced through the needle, allowing for the advancement of a catheter over the guidewire into the proximal abdominal aorta, specifically the suprarenal region. This process is guided by real-time X-ray imaging, ensuring precise placement of the catheter. Once the catheter is correctly positioned, a contrast dye is injected into the aorta, enabling visualization of blood flow as it travels through the vessel. This is achieved through a series of images, known as serialography, which capture the movement of the dye and provide critical information regarding the aorta's condition. The images obtained during this procedure are essential for further analysis, allowing for comparisons with previous studies and aiding in the diagnosis of potential vascular issues. The CPT® Code 75625 specifically denotes the radiologist's role in supervising the entire abdominal aortogram imaging process, which includes the nonselective placement of the catheter, the review of relevant medical records, the interpretation of the resulting images, and the generation of a comprehensive written report detailing the findings.
