OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.

Home-use interferential stimulation devices

Interferential stimulation devices are considered investigational and are not covered.

Investigational equipment: There is insufficient evidence from peer-reviewed literature demonstrating that interferential stimulation is an effective treatment of pain for home use or any other indication.

Because the equipment is investigational, it is not covered.

Interferential stimulation devices for home use or any other indication are excluded from coverage because the treatment is considered investigational.

Interferential stimulation is not considered medically necessary because insufficient peer-reviewed evidence demonstrates its effectiveness for treating pain or any other indication.
