CPT® Code 75958

Placement of proximal extension prosthesis for endovascular repair of descending thoracic aorta (eg, aneurysm, pseudoaneurysm, dissection, penetrating ulcer, intramural hematoma, or traumatic disruption), radiological supervision and interpretation

The CPT® Code 75958 refers to the placement of a proximal extension prosthesis specifically for the endovascular repair of the descending thoracic aorta. This procedure is indicated for various conditions affecting the aorta, including aneurysms, pseudoaneurysms, dissections, penetrating ulcers, intramural hematomas, or traumatic disruptions. The procedure involves the use of advanced imaging techniques, particularly radiological supervision and interpretation, to ensure accurate placement and functionality of the prosthesis. During the procedure, comprehensive imaging is conducted, which includes angiography of the aorta and its branches prior to the deployment of the endovascular extension prosthesis. This imaging is crucial for visualizing the aortic anatomy and planning the intervention. The use of fluoroscopic guidance throughout the procedure aids in the precise placement of guidewires, catheters, and the prosthesis itself. Additionally, intraprocedural angiography is performed to confirm the correct positioning of the prosthesis, detect any potential endoleaks, and evaluate blood flow. A post-deployment aortogram is also conducted to assess the position of the extension prosthesis, check for endoleaks, and ensure the patency of the aorta. The physician is responsible for providing a written interpretation of all angiographic and fluoroscopic imaging performed during the procedure, ensuring comprehensive documentation and analysis of the intervention.
