CPT® Code 93592

Add-On Code

Percutaneous transcatheter closure of paravalvular leak; each additional occlusion device (List separately in addition to code for primary procedure)

A paravalvular leak (PVL) refers to an abnormal connection that occurs around a prosthetic heart valve, specifically the mitral or aortic valve, where blood can flow back into the heart chamber instead of moving forward through the valve. This condition arises when the seal between the prosthetic valve and the surrounding native tissue fails to form properly, leading to potential complications such as endocarditis, hemolytic anemia, and heart failure. The procedure described by CPT® Code 93592 involves the percutaneous transcatheter closure of these leaks using occlusion devices. This minimally invasive technique is performed by inserting a vascular catheter through the femoral artery, which is then navigated to the heart. Depending on the approach—antegrade or retrograde—the catheter is maneuvered to the appropriate heart chamber to access the leak. The deployment of occlusion devices is critical, especially for larger defects that may require multiple devices to ensure complete closure. The use of this code indicates that additional occlusion devices are being utilized in conjunction with a primary procedure, highlighting the complexity and necessity of addressing multiple leaks during a single intervention.
