CPT® Code 33368

Add-On Code

Transcatheter aortic valve replacement (TAVR/TAVI) with prosthetic valve; cardiopulmonary bypass support with open peripheral arterial and venous cannulation (eg, femoral, iliac, axillary vessels) (List separately in addition to code for primary procedure)

Transcatheter aortic valve replacement (TAVR/TAVI) is a minimally invasive procedure designed to treat aortic stenosis, a condition characterized by the narrowing of the aortic valve, which can lead to significant heart complications. During this procedure, a prosthetic valve is inserted to replace the diseased valve, allowing for improved blood flow and heart function. The procedure is particularly beneficial for patients who may be at high risk for traditional open-heart surgery due to age, comorbidities, or other health factors. When TAVR/TAVI is performed with the support of cardiopulmonary bypass (CPB), it involves the use of specialized equipment to temporarily take over the function of the heart and lungs, ensuring that blood is circulated and oxygenated while the surgical team works on the heart. This support is crucial in certain cases where the patient's vascular anatomy or body habitus complicates the procedure. The use of open peripheral arterial and venous cannulation, such as through the femoral, iliac, or axillary vessels, is a key aspect of establishing CPB during TAVR/TAVI. This code (CPT® 33368) is specifically used to report the additional services provided during the procedure when CPB is utilized, ensuring that all aspects of the surgical intervention are accurately captured for billing and documentation purposes.
