CPT code 37193 represents percutaneous endovascular removal of an inferior vena cava (IVC) filter using catheter-directed techniques and imaging guidance. This procedure is clinically important because retrieval of temporary or retrievable IVC filters reduces long-term complications associated with indwelling filters, such as migration, fracture, and thrombosis. Nationally, appropriate coding and coverage policies for filter retrieval influence utilization, access to interventional radiology services, and post-thromboembolic care pathways.
