CPT® Code 64598

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 Finally, the introducer needle used during the procedure is withdrawn, and the incision is closed using sutures or staples, completing the process.
