The procedure described by CPT® Code 64598 involves the revision or removal of a neurostimulator electrode array that is implanted in a peripheral nerve, along with an integrated neurostimulator. This procedure is typically performed on patients who have previously undergone implantation of a single-unit peripheral nerve neurostimulator, which is designed to alleviate intractable pain by delivering mild electrical impulses that disrupt the transmission of pain signals along the nerve pathways. In cases where the neurostimulator is not functioning as intended or if the patient experiences discomfort or intolerance to the device, it may become necessary to either reposition the electrode array or remove it entirely. The procedure is conducted under local anesthesia, ensuring that the patient remains comfortable while allowing the physician to access the implanted device. A small incision is made over the site of the implanted electrode, facilitating the revision or removal process. To enhance the accuracy of the procedure, ultrasound or active stimulation guidance may be employed, which assists the physician in correctly repositioning the electrode array if needed. Following the adjustment or removal, the physician may also re-evaluate and program the transmitter and remote device to optimize the stimulation settings for the patient’s needs. Finally, the introducer needle used during the procedure is withdrawn, and the incision is closed using sutures or staples, completing the process.

The procedure associated with CPT® Code 64598 is indicated for patients experiencing issues with a previously implanted peripheral nerve neurostimulator and electrode array. The specific indications for this procedure include:
The procedure for CPT® Code 64598 involves several critical steps to ensure the effective revision or removal of the neurostimulator electrode array:
Post-procedure care for patients undergoing CPT® Code 64598 includes monitoring for any immediate complications related to the incision site and the functionality of the neurostimulator. Patients may be advised on wound care to prevent infection and ensure proper healing. Follow-up appointments may be scheduled to assess the effectiveness of the repositioned or newly programmed neurostimulator and to make any necessary adjustments to the stimulation settings. Patients should also be informed about potential signs of complications, such as increased pain, swelling, or unusual sensations, and instructed to contact their healthcare provider if these occur.
