The procedure described by CPT® Code 37620 involves the interruption of blood flow in the inferior vena cava (IVC), which is a major vein that carries deoxygenated blood from the lower body to the heart. This interruption can be either partial or complete and is performed to prevent the occurrence of pulmonary embolism, a serious condition that arises when blood clots, known as deep vein thromboses, migrate from the pelvis or lower extremities to the lungs. The physician may utilize different techniques to achieve this interruption. An extravascular approach includes methods such as suture, ligation, plication, or the application of a clip to the IVC. Alternatively, an intravascular approach may involve the placement of a filter within the IVC, which is designed to capture blood clots and prevent them from traveling to the lungs. These filters are often umbrella-shaped devices that expand within the vein to trap clots. Prior to performing the interruption, a cavogram is conducted to assess the vascular anatomy and to ensure that there are no existing thrombi within the IVC. If the extravascular technique is chosen, the procedure necessitates an abdominal incision to expose the IVC, allowing the surgeon to manipulate the vessel directly. Conversely, if the intravascular technique is selected, access is gained through either the femoral or jugular vein, and a series of steps involving guidewires and catheters are followed to position the filter accurately within the IVC. This comprehensive approach ensures that the procedure is tailored to the patient's specific anatomical and clinical needs while effectively mitigating the risk of pulmonary embolism.

The procedure described by CPT® Code 37620 is indicated for patients at risk of pulmonary embolism due to the presence of deep vein thromboses (DVT) in the pelvis or lower extremities. The following conditions may warrant the performance of this procedure:
The procedure for CPT® Code 37620 involves several critical steps, which can be performed using either an extravascular or intravascular technique. The following outlines the procedural steps:
After the completion of the procedure, patients are typically monitored for any immediate complications, such as bleeding or infection at the incision site. Recovery may vary depending on the technique used; however, patients are generally advised to follow up with their healthcare provider for imaging studies to ensure the filter is functioning correctly and to monitor for any potential complications. Instructions regarding activity restrictions and signs of complications, such as leg swelling or pain, should be provided to the patient to ensure proper recovery and management.
