CPT® Code 37192

Repositioning of intravascular vena cava filter, endovascular approach including vascular access, vessel selection, and radiological supervision and interpretation, intraprocedural roadmapping, and imaging guidance (ultrasound and fluoroscopy), when performed

The procedure described by CPT® Code 37192 involves the repositioning of an intravascular vena cava filter using an endovascular approach. This procedure is typically indicated when a vena cava filter has migrated from its original placement or when it is being used temporarily to prevent complications such as fibrosis or permanent fixation of the filter to the wall of the vena cava. The repositioning process is critical to ensure the filter functions effectively in preventing emboli from reaching the pulmonary circulation. During the procedure, a cavogram is performed to visualize the filter's location and to check for any clots that may be trapped at the filter site, which is essential for patient safety. The physician gains access to the vascular system through either the femoral or jugular vein, utilizing an introducer sheath to facilitate the procedure. Radiological guidance, including ultrasound and fluoroscopy, is employed throughout the process to ensure accurate navigation and positioning of the filter. This comprehensive approach not only aids in the successful repositioning of the filter but also minimizes the risk of complications associated with the procedure.
