CPT® Code 33289

Transcatheter implantation of wireless pulmonary artery pressure sensor for long-term hemodynamic monitoring, including deployment and calibration of the sensor, right heart catheterization, selective pulmonary catheterization, radiological supervision and interpretation, and pulmonary artery angiography, when performed

The procedure described by CPT® Code 33289 involves the transcatheter implantation of a wireless pulmonary artery pressure sensor, which is a critical tool for long-term hemodynamic monitoring. This sensor is designed to detect sudden increases in right heart filling pressure, which can indicate worsening heart failure or an imminent exacerbation of the condition. By identifying these changes early, healthcare providers can initiate medical interventions before the patient experiences significant symptoms. The wireless nature of the sensor allows it to transmit pressure readings using radiofrequency magnetic telemetry, facilitating continuous monitoring without the need for invasive procedures after implantation.

During the procedure, the patient is typically brought to a cardiac catheterization laboratory, where a percutaneous access point is established in the femoral vein located in the groin. This access allows for the introduction of various catheters necessary for the procedure. The process includes several key steps such as right heart catheterization, selective pulmonary catheterization, and, if performed, pulmonary artery angiography. Radiological supervision and interpretation are also integral to ensure the accurate placement of the sensor and to monitor the procedure's progress. Overall, this advanced technique enhances the ability to manage heart failure by providing real-time data on pulmonary artery pressures, thereby improving patient outcomes through timely interventions.
