Official Description

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

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The repositioning of an intravascular vena cava filter is performed under specific clinical circumstances. The following indications are explicitly associated with this procedure:

  • Migrated Filter The procedure is indicated when a vena cava filter has moved from its intended position, necessitating repositioning to ensure its effectiveness in preventing emboli.
  • Temporary Use It is also indicated for filters that are being used temporarily, where repositioning is required to prevent fibrosis and permanent fixation of the filter to the vena cava wall.

2. Procedure

The procedure for repositioning an intravascular vena cava filter involves several critical steps, each performed with precision to ensure patient safety and procedural success:

  • Cavogram Acquisition Initially, a cavogram is obtained to locate the existing filter and to assess for any clots that may be trapped at the filter site. This imaging step is crucial for planning the subsequent steps of the procedure.
  • Vascular Access The physician then exposes either the femoral or jugular vein, depending on the chosen access route. An introducer sheath is placed into the selected blood vessel to facilitate access to the vascular system.
  • Guidewire Insertion Under radiological guidance, a guidewire is inserted through the introducer sheath and advanced through the femoral and iliac veins into the inferior vena cava (IVC). If a jugular vein approach is utilized, the guidewire is advanced through the jugular and brachiocephalic veins, superior vena cava, right atrium, and into the IVC as necessary.
  • Filter Retrieval Catheter Advancement A filter retrieval catheter is then advanced over the guidewire to reach the filter. Once the catheter is in position, the guidewire is removed to allow for the next steps.
  • Snaring the Filter The hook at the apex of the filter is snared to facilitate its removal. This step is critical to ensure that the filter can be disengaged from the wall of the vena cava.
  • Sheath Advancement The outer sheath is advanced over the anchoring hooks of the filter struts until they are fully disengaged from the vena cava wall. The sheath continues to be advanced until the filter is completely collapsed but not entirely covered by the sheath.
  • Filter Repositioning The filter is then repositioned and redeployed into the desired location within the vena cava. This step is essential to restore the filter's functionality.
  • Loop Snare Disengagement After repositioning, the loop snare is disengaged from the hook at the apex of the filter, and the retrieval set is removed from the vascular system.
  • Additional Cavograms Additional cavograms may be obtained as needed to evaluate the positioning of the filter post-redeployment, ensuring that it is correctly placed.
  • Closure of Incision Finally, the incision made in the neck or groin is closed, completing the procedure.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any complications that may arise following the repositioning of the vena cava filter. Patients are typically observed for signs of bleeding or infection at the access site. Follow-up imaging may be required to confirm the proper positioning of the filter and to ensure that there are no complications such as thrombosis. The healthcare team will provide specific instructions regarding activity restrictions and any necessary follow-up appointments to assess the patient's recovery and the filter's function.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).

XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
