Interferential Stimulator

Section: Durable Medical Equipment
Effective Date: July 01, 2018
Revised Date: May 14, 2018

Description

Interferential stimulation is a type of electrical nerve stimulation that uses paired electrodes of two independent circuits carrying medium-frequency alternating currents. The electrodes are aligned on the skin so that the current flowing between each pair intersects at the underlying target. This maximizes the current permeating the tissues while minimizing unwanted stimulation of cutaneous nerves.

Criteria

Coverage is subject to the specific terms of the member's benefit plan. Interferential stimulation is experimental/investigational.

Review of available literature reveals a lack of controlled clinical trials that prove the effectiveness of the procedure.
