CPT® Code 64595

Revision or removal of peripheral, sacral, or gastric neurostimulator pulse generator or receiver, with detachable connection to electrode array

The CPT® Code 64595 refers to the procedure involving the revision or removal of a peripheral, sacral, or gastric neurostimulator pulse generator or receiver that has a detachable connection to an electrode array. This procedure is essential for managing patients who have undergone neurostimulation therapy for various conditions, such as chronic pain, bladder or bowel dysfunction, or gastroparesis. The neurostimulator pulse generator is an implantable device that generates electrical impulses, which are delivered to specific electrodes implanted in the body. These impulses are designed to stimulate nerves in targeted areas, thereby alleviating symptoms associated with the patient's condition. In the context of gastric neurostimulation, the device delivers mild electrical impulses to the antrum of the stomach, which can help improve gastric motility in patients suffering from gastroparesis. For sacral neurostimulation, the device targets nerves that control bladder and bowel functions, aiming to restore normal physiological activity. Peripheral nerve stimulation, on the other hand, focuses on delivering impulses to specific areas to manage chronic pain effectively. The procedure described by CPT® Code 64595 encompasses both the revision and complete removal of the neurostimulator device. During revision, the existing device is evaluated, and necessary adjustments are made to ensure its proper functioning. This may involve detaching the device from the electrodes and removing it entirely if required. The procedure is performed through an incision in the skin, allowing access to the subcutaneous pocket where the device is located. The careful handling of the device and electrodes is crucial to maintain the integrity of the surrounding tissue and ensure optimal outcomes for the patient.
