Official Description

Transcatheter placement of wireless physiologic sensor in aneurysmal sac during endovascular repair, including radiological supervision and interpretation, instrument calibration, and collection of pressure data (List separately in addition to code for primary procedure)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 34806 refers to the transcatheter placement of a wireless physiologic sensor within an aneurysmal sac during an endovascular repair procedure. This specialized sensor, comparable in size to a grain of rice, is designed to monitor critical physiological parameters such as pressure, flow, and temperature within the aorta after the repair of an abdominal aortic aneurysm (AAA). The placement of this sensor is crucial as it allows for continuous, noninvasive monitoring of the aneurysmal sac, which is essential for detecting potential complications such as endoleaks or recurrent pressurization that may occur even after the aneurysm has been repaired. The sensor operates using acoustic waves, which can effectively transmit data through various tissues, including soft tissue, bone, and fluid, without being absorbed. This technology requires minimal energy while providing a high signal-to-noise ratio, making it suitable for deep tissue monitoring. Notably, the sensor does not have a battery, antenna, or connecting leads, which enhances its functionality and ease of use. The procedure involves the use of an introducer catheter and guidewire to position the sensor accurately within the aneurysmal sac under fluoroscopic guidance. The sensor is tethered in place during calibration, and two critical measurements are taken: a pre-exclusion measurement before the endovascular stent is placed, and a post-exclusion measurement after the stent placement. This comprehensive approach ensures that the sensor remains correctly positioned and functional, providing vital data for ongoing patient management following the endovascular repair of an AAA.

1. Indications

The transcatheter placement of a wireless physiologic sensor (CPT® Code 34806) is indicated for patients undergoing endovascular repair of an abdominal aortic aneurysm (AAA). The procedure is particularly relevant for monitoring the following conditions:

  • Abdominal Aortic Aneurysm (AAA) - The sensor is utilized to monitor the pressure within the aneurysmal sac post-repair, which is critical for assessing the success of the procedure and identifying potential complications.
  • Risk of Endoleaks - The sensor helps in detecting endoleaks, which can occur when the aneurysmal sac is not completely isolated, leading to recurrent pressurization.
  • Monitoring for Rupture Risk - Continuous monitoring of pressure, flow, and temperature allows for early detection of changes that may indicate an increased risk of rupture.

2. Procedure

The procedure for the transcatheter placement of the wireless physiologic sensor involves several critical steps to ensure accurate positioning and functionality:

  • Step 1: Preparation and Access - The procedure begins with the patient being positioned appropriately, and access to the vascular system is obtained using standard techniques. An introducer catheter is inserted into the appropriate vascular access site.
  • Step 2: Guidewire Placement - A guidewire is advanced through the introducer catheter and positioned outside the main body of the endograft. This step is crucial for the subsequent placement of the sensor.
  • Step 3: Sensor Delivery - The sensor delivery system is then advanced over the guidewire. Under fluoroscopic guidance, the sensor is carefully positioned within the aneurysmal sac, ensuring it is placed accurately for optimal monitoring.
  • Step 4: Calibration and Measurement - Once the sensor is in place, it is tethered to maintain its position while calibration is performed. Two critical measurements are taken: the pre-exclusion measurement is recorded before the endovascular stent is placed, and the post-exclusion measurement is taken after the stent placement.
  • Step 5: Verification - After the post-exclusion measurement, the position of the sensor is checked again to confirm that it remains correctly located at the top of the aneurysmal sac. This verification is essential to ensure the accuracy of the data collected.
  • Step 6: Withdrawal of Delivery System - Finally, the delivery system is withdrawn, leaving the sensor in place for ongoing monitoring.

3. Post-Procedure

After the placement of the wireless physiologic sensor, the patient will be monitored for any immediate complications related to the procedure. The sensor will provide continuous data on pressure, flow, and temperature, which will be crucial for assessing the patient's recovery and the integrity of the aneurysmal sac. Regular follow-up appointments may be scheduled to review the data collected by the sensor and to ensure that the patient remains stable. Any significant changes in the monitored parameters may prompt further investigation or intervention to address potential complications such as endoleaks or other issues related to the AAA repair.
