CPT® Code 75952

Deleted

The CPT® Code 75952 refers to the endovascular repair of an infrarenal abdominal aortic aneurysm or dissection, specifically focusing on the radiological supervision and interpretation involved in the procedure. This procedure is critical for patients with an infrarenal abdominal aortic aneurysm, which is a localized enlargement of the abdominal aorta occurring below the renal arteries, or for those experiencing a dissection, where there is a tear in the aorta's inner layer. The role of radiological supervision and interpretation is essential throughout the endovascular repair process. It encompasses several key components, including the performance of angiography of the aorta and its branches prior to the deployment of the endovascular prosthesis. This initial imaging is crucial for assessing the anatomy and planning the repair. During the procedure, fluoroscopic guidance is utilized to ensure accurate placement of various components, such as guidewires, catheters, and the endovascular prosthesis itself. This guidance is vital for the successful delivery and positioning of the prosthesis, as well as for any necessary balloon dilation to secure the prosthesis in place. Additionally, intraprocedural angiography is conducted to confirm the correct positioning of the prosthesis, detect any potential endoleaks—where blood leaks back into the aneurysm sac—and evaluate the blood flow to the surrounding vessels. A post-deployment aortogram is also performed to assess the position of the prosthesis, check for endoleaks, and ensure the patency of critical arteries, including the renal, hypogastric, lumbar, and inferior mesenteric arteries. The physician is responsible for providing a comprehensive written interpretation of all angiographic and fluoroscopic imaging conducted during the procedure, which is essential for documenting the outcomes and guiding further patient management.
