Interferential Therapy

Interferential or sympathetic therapy is a type of electrical stimulation of the peripheral nerves that is designed to alleviate pain by inducing a systemic effect on sympathetically induced pain.  Interferential stimulation is customarily provided on an out-patient basis for about 20 treatment sessions followed by purchase of a home unit for the patient to self-administer the interferential therapy for an unlimited period of time. Following a review of the literature and coverage policies of other third party insurers, BWC has determined that insufficient evidence exists to determine the effectiveness of “self-administered” sympathetic therapy/ interferential therapy. BWC and the MCO will not reimburse the rental or purchase of a therapy unit used to self-administer interferential therapy.
