CPT® Code 33288

Removal and replacement of phrenic nerve stimulator, including vessel catheterization, all imaging guidance, and interrogation and programming, when performed; transvenous stimulation or sensing lead(s)

The procedure described by CPT® Code 33288 involves the removal and replacement of a phrenic nerve stimulator, which is a medical device implanted to assist patients with moderate to severe central sleep apnea (CSA) by stimulating the diaphragm to contract, thereby facilitating rhythmic breathing. This procedure is essential for patients who rely on the stimulator for respiratory support. The process includes several critical components: vessel catheterization, imaging guidance, and interrogation and programming of the device, all of which are integral to ensuring the successful replacement of the stimulator. The removal and replacement procedure begins with an incision over the existing device, allowing access to the subcutaneous pocket where the stimulator is located. The existing device and its lead(s) are carefully detached from surrounding tissues, ensuring minimal trauma to the area. The procedure may involve the use of fluoroscopic guidance to assist in the safe removal of the lead(s) and the placement of new leads, which are crucial for the device's functionality. The entire process is designed to restore the patient's ability to breathe normally during sleep, addressing the serious health implications associated with CSA.
