CPT® Code 64596

Insertion or replacement of percutaneous electrode array, peripheral nerve, with integrated neurostimulator, including imaging guidance, when performed; initial electrode array

The procedure described by CPT® Code 64596 involves the insertion or replacement of a percutaneous electrode array that is designed for peripheral nerve stimulation. This procedure is specifically aimed at patients suffering from intractable pain, which is pain that does not respond to conventional treatments. The device used in this procedure is a small, single-unit neurostimulator and electrode array, comparable in size to a standard staple. Its primary function is to disrupt the transmission of pain signals from the affected nerve to the brain by delivering mild electrical impulses once activated. The procedure begins with the identification of the target nerve, followed by the administration of local anesthesia to ensure patient comfort. An introducer needle is then utilized to position the integrated neurostimulator and electrode array adjacent to the nerve, with imaging guidance, typically ultrasound, to enhance accuracy. The external pulse transmitter, which is worn externally over the electrode, allows for wireless stimulation of the nerve through a handheld remote control that is programmed by a qualified healthcare professional. This setup enables the physician to adjust the stimulation settings to optimize pain relief for the patient. Additionally, if necessary, more electrode arrays can be inserted during the same session, as indicated by CPT® Code 64597, allowing for a comprehensive approach to managing the patient's pain.
