CPT® Code 33278

Removal of phrenic nerve stimulator, including vessel catheterization, all imaging guidance, and interrogation and programming, when performed; system, including pulse generator and lead(s)

The procedure described by CPT® Code 33278 involves the removal of a phrenic nerve stimulator system, which is specifically utilized for the treatment of central sleep apnea (CSA). This complex surgical intervention is necessitated by the challenges presented in patients who often have underlying conditions such as heart failure and reduced ejection fraction. The procedure entails the careful extraction of the neurostimulator system, which includes an implantable pulse generator and one or more leads, typically positioned in critical vascular structures like the brachiocephalic or pericardiophrenic vein. Due to the anatomical location of these components, there is a significant risk of vascular or cardiac damage during the removal process. The procedure is performed under general anesthesia to ensure patient comfort and safety. It is important to note that while the removal of the entire system is the focus of this code, there are instances where only a lead or the generator may be removed, although these cases are less common. The removal process requires meticulous attention to detail, as the surgeon must navigate the surrounding tissues and ensure that hemodynamic stability is maintained throughout the procedure.
