Angiography, arteriovenous shunt (eg, dialysis patient fistula/graft), complete evaluation of dialysis access, including fluoroscopy, image documentation and report (includes injections of contrast and all necessary imaging from the arterial anastomosis and adjacent artery through entire venous outflow including the inferior or superior vena cava), radiological supervision and interpretation

The CPT® Code 75791 refers to a specialized imaging procedure known as angiography, specifically targeting arteriovenous shunts, which are commonly utilized in patients undergoing dialysis. This complete evaluation of dialysis access involves a thorough assessment of the shunt, including the arteriovenous fistula or graft. The procedure is characterized by the use of fluoroscopy, a real-time imaging technique that allows for the visualization of the shunt and surrounding blood vessels during the injection of contrast media. The physician plays a crucial role in this process, providing radiological supervision and interpretation throughout the procedure. The term 'shuntogram' or 'fistulogram' may also be used to describe this procedure, highlighting its focus on the evaluation of the vascular access points used for dialysis. During the angiography, contrast material is injected into the arteriovenous shunt or an adjacent blood vessel, enabling the capture of a series of radiographs at specific intervals. This imaging captures the flow of blood through the shunt and adjacent vessels, allowing the physician to monitor and assess the functionality of the dialysis access. Following the imaging, the physician reviews the obtained radiographs and compiles a comprehensive written report interpreting the findings, which is essential for determining the adequacy and patency of the dialysis access site.
