Note: When used for the treatment in section II, the TENS unit must be used by the beneficiary on a trial basis for a minimum of one month (30 days), The trial period must be monitored by the physician to determine the effectiveness of the TENS unit in modulating the pain. For use beyond 30 days the physician must document that the patient is likely to derive significant therapeutic benefit from continuous use of the unit over a long period of time
