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)

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.
