In simple words: This procedure corrects or replaces a part of a spinal cord stimulator that's under the skin. The doctor uses a special x-ray to make sure it's in the right place.

This procedure involves revising or replacing a previously placed percutaneous spinal neurostimulator electrode array. It includes the use of fluoroscopy for guidance. The procedure is typically performed to improve the effectiveness of the spinal cord stimulator by correcting electrode movement or addressing a component malfunction. It involves incising the previous implant site, dissecting down to the lead, and either adjusting the existing electrodes or removing them and placing a new array. Fluoroscopy is used to confirm proper placement in the epidural space. The leads are then anchored, connected to the pulse generator or receiver, and the incision is closed.

Example 1: A patient with a spinal cord stimulator experiences recurrent pain due to electrode migration. The physician performs a revision of the electrode array using fluoroscopic guidance to reposition the electrodes., A patient's spinal cord stimulator malfunctions due to a faulty electrode. The physician replaces the percutaneous electrode array with a new one, using fluoroscopy to ensure correct placement., A patient requires an upgrade to a more advanced spinal cord stimulator electrode array. The physician removes the old array and inserts the new one percutaneously, guided by fluoroscopy.

Documentation should include the reason for the revision or replacement, the type of electrode array used, the location of the array, the use of fluoroscopy, and any complications encountered.
