Somatosensory Testing

Short-latency somatosensory evoked potentials (SEPs) are covered to evaluate proximal nerve segments and central somatosensory pathway integrity for a range of neurologic conditions (e.g., multiple sclerosis, cervical myelopathy, spinal cord trauma, peripheral neuropathies) and for intraoperative monitoring during spinal surgery with risk of nerve/spinal cord injury. Coverage requires that prior detailed clinical history, neurologic exam, imaging, and EMG/nerve conduction studies have failed to provide adequate information for a specific treatment plan, and the test must be performed and interpreted by providers with documented specialized training.

"Short-latency somatosensory evoked potentials (SEPs) are covered to assist diagnosis of multiple sclerosis when slowing of somatosensory conduction is suspected."
