Official Description

Retrieval (removal) 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

Common Language Description

The procedure described by CPT® Code 37193 involves the retrieval or removal of an intravascular vena cava filter using an endovascular approach. This procedure is typically performed when a vena cava filter, which is designed to prevent blood clots from traveling to the lungs, needs to be removed due to various clinical reasons. The process begins with the physician obtaining a cavogram, a type of imaging study, to accurately locate the filter and to check for any clots that may be trapped at the filter site. Access to the vascular system is achieved through either the femoral or jugular vein, where an introducer sheath is placed to facilitate the procedure. Under the guidance of imaging techniques such as ultrasound and fluoroscopy, a guidewire is carefully inserted and navigated through the venous system, reaching the inferior vena cava (IVC). Depending on the access point, the guidewire may traverse through the femoral and iliac veins or, in the case of a jugular approach, through the jugular and brachiocephalic veins, superior vena cava, and right atrium. Once the guidewire is in place, a filter retrieval catheter is advanced over it to reach the filter. The retrieval process involves snaring the hook at the apex of the filter and advancing an outer sheath over the anchoring hooks of the filter struts, disengaging them from the wall of the vena cava. The sheath is then advanced until the filter is fully collapsed and enclosed within it, allowing for safe removal of both the filter and the retrieval set. Following the retrieval, additional cavograms may be performed to assess blood flow and to ensure that there is no trauma to the vena cava or surrounding structures. Finally, the incision made during the procedure, whether in the neck or groin, is closed to complete the process.

1. Indications

The retrieval of an intravascular vena cava filter is indicated in specific clinical scenarios where the filter is no longer needed or may pose a risk to the patient. The following conditions may warrant this procedure:

  • Filter Removal Due to Resolution of Indications The procedure is performed when the original reason for placing the vena cava filter, such as the presence of a deep vein thrombosis or pulmonary embolism, has resolved.
  • Filter Complications The retrieval may be necessary if the filter has caused complications, such as migration, fracture, or thrombosis.
  • Patient's Clinical Status Change If a patient's clinical status changes, indicating that the risks of leaving the filter in place outweigh the benefits, retrieval may be indicated.

2. Procedure

The procedure for the retrieval of 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 vena cava filter and to assess for any clots that may be trapped at the filter site. This imaging step is crucial for planning the retrieval process.
  • Vascular Access The physician then exposes either the femoral or jugular vein to gain access to the vascular system. An introducer sheath is placed into the selected blood vessel to facilitate the subsequent steps of the procedure.
  • Guidewire Insertion Under radiological guidance, a guidewire is inserted through the introducer sheath and advanced through the femoral and iliac veins, ultimately reaching the inferior vena cava. If a jugular vein approach is utilized, the guidewire is navigated through the jugular and brachiocephalic veins, superior vena cava, and right atrium to access the inferior vena cava.
  • Filter Retrieval Catheter Advancement Once the guidewire is in position, a filter retrieval catheter is advanced over the guidewire until it reaches the filter. This step is critical for the successful retrieval of the filter.
  • Filter Snaring The guidewire is then removed, and the hook at the apex of the filter is snared to facilitate its removal from the vena cava.
  • Sheath Advancement An outer sheath is advanced over the anchoring hooks of the filter struts, disengaging them from the wall of the vena cava. This step is essential to ensure that the filter can be safely collapsed and removed.
  • Filter Collapse and Removal The sheath continues to be advanced until the filter is completely collapsed and enclosed within it. The filter, along with the retrieval set, is then removed from the body.
  • Post-Retrieval Imaging Additional cavograms may be obtained as needed to evaluate blood flow and to ensure that there is no trauma to the vena cava or surrounding structures following the retrieval.
  • Incision Closure Finally, the incision made in the neck or groin during the procedure is closed, completing the process.

3. Post-Procedure

After the retrieval of the vena cava filter, patients are typically monitored for any immediate complications or adverse effects. Post-procedure care may include observation for signs of bleeding or infection at the incision site. Patients may also undergo follow-up imaging studies to ensure that the vena cava and surrounding structures are intact and functioning properly. Recovery time can vary based on the individual patient's health status and the complexity of the procedure, but most patients can expect to resume normal activities within a short period, barring any complications.

X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
