Official Description

Removal of cranial nerve (eg, vagus nerve) neurostimulator electrode array and pulse generator

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 64570 involves the removal of a cranial nerve neurostimulator electrode array and its associated pulse generator. A neurostimulator is a device that delivers electrical impulses to specific nerves to modulate their activity, which can be beneficial in managing various medical conditions. The vagus nerve is one of the most commonly targeted cranial nerves for stimulation, particularly in the treatment of epilepsy, where it helps to control and reduce the frequency of seizures. The removal process entails careful dissection to expose the electrode array and pulse generator, ensuring that surrounding tissues are preserved as much as possible. This procedure is critical when the neurostimulator is no longer functioning properly or when a patient requires a revision or replacement of the device. The removal must be performed with precision to avoid damage to the nerve and surrounding structures, and it typically involves closing the incisions in layers to promote proper healing post-operation.

1. Indications

The procedure associated with CPT® Code 64570 is indicated for the removal of a cranial nerve neurostimulator electrode array and pulse generator. This may be necessary in the following situations:

  • Device Malfunction The neurostimulator may be malfunctioning or defective, necessitating its removal to prevent complications or ineffective treatment.
  • Device Replacement The procedure may be indicated when a new neurostimulator is to be implanted, requiring the removal of the existing electrode array and pulse generator.
  • Patient Discontinuation If a patient no longer requires neurostimulation therapy, the removal of the device is indicated.

2. Procedure

The procedure for CPT® Code 64570 involves several critical steps to ensure the safe and effective removal of the neurostimulator components.

  • Step 1: Exposure of the Device The first step involves making an incision to expose the cranial nerve neurostimulator electrode array and pulse generator. This is done with careful dissection to minimize trauma to surrounding tissues.
  • Step 2: Detachment of the Generator Once the device is exposed, the pulse generator is detached from the array wires. This step is crucial to ensure that the generator can be safely removed without damaging the electrode array.
  • Step 3: Removal of the Generator After detaching the generator, it is carefully removed from its subcutaneous pocket. This requires precision to avoid any injury to the surrounding structures.
  • Step 4: Dissection of the Electrode Array The next step involves dissecting the electrode array free from the surrounding tissues. This is done meticulously to ensure that the cranial nerve and adjacent tissues are not harmed during the removal process.
  • Step 5: Removal of the Electrode Array and Wires Following the dissection, the electrode array and its wires are removed from the surgical site. This step completes the removal of the neurostimulator components.
  • Step 6: Closure of Incisions Finally, the incisions made during the procedure are closed. This is typically done in layers to promote optimal healing and minimize scarring.

3. Post-Procedure

After the procedure associated with CPT® Code 64570, patients may require monitoring for any immediate complications related to the surgery. Post-operative care typically includes pain management and instructions for wound care to ensure proper healing. Patients should be advised to watch for signs of infection, such as increased redness, swelling, or discharge from the incision site. Follow-up appointments may be necessary to assess the surgical site and ensure that the patient is recovering appropriately. Additionally, any further treatment options or adjustments to the patient's care plan should be discussed during these follow-up visits.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
