Surface Scanning and Macro Electromyography

Aetna considers high‑density/surface scanning/paraspinal/macro EMG, surface EMG for nocturnal bruxism, the Neurophysiologic Pain Profile/spine matrix scan, and spinoscopy experimental/investigational and therefore not covered because their reliability, validity, and clinical value have not been established. Conventional needle EMG and use of surface electrodes for EMG biofeedback are not affected and remain medically necessary for appropriate indications.
