Evoked Potentials 2.01.27
Policy 2.01.27 sets the indications considered medically appropriate for visual-evoked, somatosensory-evoked and auditory-evoked potentials, with a current effective date of May 21, 2026. Intra-operative neurophysiologic monitoring is considered medically appropriate during high-risk thyroid or parathyroid surgery, or during spinal, intracranial or vascular procedures, and all other indications for intra-operative neurophysiologic monitoring are considered not medically necessary. Vestibular evoked myogenic potentials, intra-operative monitoring of visual-evoked potentials, visual-evoked potential testing for glaucoma, and transcranial magnetic stimulation to elicit motor-evoked potentials are considered investigational.
