The CPT® Code 75993 refers to a specific medical procedure known as transluminal atherectomy, which is performed on peripheral arteries, particularly those located in the legs or arms. This procedure is utilized when an artery has become obstructed due to the accumulation of plaque, a fatty substance that can restrict blood flow. During the atherectomy, the physician employs specialized instruments, including an atherectomy catheter, which is designed to cut through the plaque buildup. This action effectively reopens the artery, allowing for improved blood circulation. The procedure is conducted under radiological supervision, meaning that the physician utilizes X-ray imaging to visualize the targeted area throughout the process. This imaging is crucial for ensuring precision and safety during the intervention. It is important to note that CPT® Code 75993 is specifically designated for each additional peripheral artery treated during the procedure, and it should be reported separately in conjunction with the primary procedure code.
