Summary & Overview
CPT 64568: Cranial Nerve Neurostimulator Implantation with Pulse Generator
CPT code 64568 identifies an open surgical implantation of a cranial nerve neurostimulator electrode array with insertion of a programmable pulse generator. This procedure is used to deliver neuromodulation therapy for conditions such as seizures, treatment-resistant depression, and other neurologic or psychiatric disorders. The code captures a complex operative intervention combining electrode placement and pulse generator implantation, with implications for surgical resource use, device costs, and long-term device management.
Key payers in the national landscape include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find information on clinical context for neuromodulation, common sites of service, and typical billing considerations. The publication summarizes national benchmarking where available, outlines relevant policy and coverage considerations reported by major payers, and provides operational context for coding and billing teams.
The content is intended to help clinical administrators, coding professionals, and policy analysts understand the clinical intent of 64568, the care settings where it is delivered, and the payer environment that influences authorization and reimbursement practices. Data not available in the input includes payer-specific payment rates, associated taxonomies, and example ICD-10 diagnoses.
Billing Code Overview
CPT code 64568 describes an open surgical implantation of a cranial nerve neurostimulator electrode array with placement of a programmable pulse generator. This service involves a surgical approach to place electrodes on or around a cranial nerve and to implant a pulse generator to deliver targeted neuromodulation therapy.
-
Service type: Implantation of cranial nerve neurostimulator with programmable pulse generator (open approach)
-
Typical site of service: Inpatient or outpatient surgical setting (operating room or procedure suite) depending on clinical indication and facility capabilities
Clinical & Coding Specifications
Clinical Context
A 42-year-old patient with medically refractory focal epilepsy is evaluated by a multidisciplinary team after failing multiple anti-seizure medications and vagus nerve stimulation. The neurosurgeon and epileptologist determine the patient is a candidate for open cranial nerve neurostimulator implantation targeting a cranial nerve distribution (for example, cortical or cranial nerve afferent stimulation) with concurrent implantation of a programmable pulse generator to permit chronic neuromodulation. Preoperative workflow includes diagnostic imaging (MRI and CT), neuropsychological testing, seizure mapping, informed consent, and anesthesia evaluation. On the day of surgery the patient undergoes a craniotomy or other open approach for placement of the cranial nerve electrode array; intraoperative neurophysiologic monitoring may be used. A subcutaneous pocket is created for the programmable pulse generator and leads are tunneled and connected. Postoperative workflow includes device programming, wound care, short inpatient observation for neurologic status and pain control, and scheduled outpatient device programming and seizure/outcome follow-up with the neurology team.
