CPT® Code 64585

The procedure described by CPT® Code 64585 involves the revision or removal of a peripheral neurostimulator electrode array. This procedure is typically performed when there is a need to either adjust the positioning of the electrode array or to remove it entirely due to malfunction or other clinical reasons. The peripheral neurostimulator is a device used to deliver electrical impulses to specific nerves, which can help manage pain or other neurological conditions. The process begins with making a skin incision over the site of the existing electrode array, allowing access to the underlying tissues. Surgeons then carefully dissect the soft tissues to expose the electrode array, ensuring minimal damage to surrounding structures. Once the array is visible, it is inspected for any issues and detached from the generator or receiver that powers it. If the array is being revised, it is tested for functionality, and any defective components are replaced. The array is then repositioned adjacent to the targeted peripheral nerve, with correct placement confirmed through motor response testing. If the decision is made to remove the array, the surgical site is closed in layers to promote proper healing. This procedure requires careful attention to detail to ensure the effectiveness of the neurostimulator and the safety of the patient.
