CPT® Code 64568

The CPT® Code 64568 refers to the open implantation of a cranial nerve neurostimulator electrode array and pulse generator. This procedure is specifically designed for the placement of a neurostimulator that targets cranial nerves, with the vagus nerve being one of the most commonly stimulated nerves, particularly for the management of epileptic seizures. The procedure involves a surgical approach where the planned insertion site, typically located in the neck, is meticulously prepared. The process begins with an incision in the skin, followed by careful dissection of the soft tissues to reveal the vagus nerve and the surrounding carotid artery sheath. Once the vagus nerve is exposed, the electrode array is strategically positioned adjacent to it. This array is then connected to a power source, allowing for stimulation to be applied while monitoring motor responses to ensure proper placement and functionality. The electrode array may be adjusted and retested multiple times to achieve optimal responses before being secured in place. Additionally, a subcutaneous pocket is created to house the pulse generator, which is connected to the electrode array through tunneled wires. After thorough testing of the generator and leads, the surgical site is closed in layers, ensuring that the electrode array remains properly positioned and secured within the neck tissues.
