CPT® Code 64569

Revision or replacement of cranial nerve (eg, vagus nerve) neurostimulator electrode array, including connection to existing pulse generator

The procedure described by CPT® Code 64569 involves the revision or replacement of a cranial nerve neurostimulator electrode array, which may include the vagus nerve, a common target for neurostimulation aimed at controlling conditions such as epilepsy. A neurostimulator electrode array is a device that delivers electrical impulses to specific nerves, helping to modulate nerve activity and alleviate symptoms associated with various neurological disorders. In this procedure, the surgeon makes an incision in the skin and carefully dissects the surrounding soft tissues to access the existing electrode array and/or pulse generator. If any components are found to be defective, they are either repaired or replaced with new ones. The new or repaired electrode array is then positioned adjacent to the targeted cranial nerve, such as the vagus nerve, and connected to the existing pulse generator. Following the connection, stimulation is applied to evaluate motor responses, and adjustments are made to ensure optimal placement and functionality of the electrode array. Once satisfactory responses are achieved, the electrode array is secured in place, and if a new array is used, the wires are tunneled to connect to the pulse generator. The procedure concludes with the closure of the incision in layers, ensuring proper healing and protection of the underlying structures.
