CPT® Code 33287

Removal and replacement of phrenic nerve stimulator, including vessel catheterization, all imaging guidance, and interrogation and programming, when performed; pulse generator

The procedure described by CPT® Code 33287 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 begins with an incision made over the existing device located in its subcutaneous pocket. The surgeon carefully dissects the surrounding tissue to free the device and its lead(s) from any adhesions. Once the existing pulse generator is removed, the surgical team assesses the pocket to determine if any revisions are necessary before placing a new generator. The existing lead(s) are then reconnected to the new device, and the pocket is subsequently closed. This procedure may also involve additional steps for the removal and replacement of stimulation or sensing lead(s), which are critical components of the phrenic nerve stimulator system. The entire process is performed under imaging guidance to ensure precision and safety, and it includes interrogation and programming of the new device to ensure optimal functionality for the patient.
