Summary & Overview
CPT 64570: Removal of Vagus Nerve Electrode Array and Pulse Generator
CPT code 64570 designates the explantation of a vagus nerve stimulation system when both the electrode array and pulse generator are removed without immediate replacement. Nationally, this code captures definitive device removal events driven by infection, device failure, or patient intolerance and is relevant to surgical, neurology, and device management workflows. Key payers typically covering this service in claims and payment analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise clinical and billing context for the procedure, discussion of common payer coverage considerations, and operational benchmarks where available. The publication outlines how CPT code 64570 is used to document complete removal of a vagus nerve electrode array and pulse generator, clarifies typical sites of service (operating room or surgical outpatient/inpatient settings), and highlights the clinical circumstances prompting removal (infection, nonresponse, intolerance). Where input data is not provided, the report notes: Data not available in the input. The content is intended to inform coding accuracy, claims submission, and administrative workflows at a national level.
Billing Code Overview
CPT code 64570 describes the surgical removal of a vagus nerve electrode array and the existing pulse generator when both devices are removed without replacement. Service Type: Explantation of vagus nerve stimulation system. Typical Site of Service: This procedure is typically performed in an operating room or other inpatient/outpatient surgical setting where device explantation can be performed under appropriate anesthesia.
This code is reported only when both the electrode array and the pulse generator are removed and no replacement device is implanted during the same encounter. The procedure may be performed for reasons such as device infection, device malfunction, or patient intolerance or nonresponse to vagus nerve stimulation therapy.
Data not available in the input.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a previously implanted vagus nerve stimulation (VNS) system who presents with device-related infection, erosion, or intolerable adverse effects (for example, recurrent severe cough, pain at the generator site, or lack of therapeutic response after adequate trial). The patient is evaluated in outpatient neurosurgery or otolaryngology clinic and found to have signs of infection (erythema, drainage) at the pulse generator pocket or along the lead tract, or the patient elects device removal for lack of efficacy. Preoperative workflow includes history and physical, medication reconciliation (notably anticoagulants), informed consent discussing removal without replacement, and perioperative antibiotics for suspected infection. Typical site of service is an operating room or ambulatory surgery center with monitored anesthesia care or general anesthesia. The procedure involves removal of the implanted pulse generator from the chest or abdominal pocket and explantation of the cervical vagus nerve electrode array and lead. Postoperative workflow includes wound care, microbiology cultures if infection suspected, documentation of device serial numbers, temporary restrictions on activity, and follow-up for wound checks and consideration of alternative therapies for the underlying condition (e.g., epilepsy or depression).
