What is the Sleep Management Program?

The Sleep Program requires prospective clinical review of non-emergency, non-inpatient sleep testing and therapy services. This program will consider the medical necessity of the sleep study as well as the clinical appropriateness of a facility test or a test done in the home. Prior authorization will also be required for any subsequent testing and therapy, both initial and ongoing.

For therapy services, members must meet usage criteria for the continued rental of equipment and replacement of supplies. Servicing physicians’ claims and durable medical equipment (DME) providers’ claims for equipment and supplies will adjudicate based on the approval or denial outcome.

Your participation is required when requesting sleep testing and therapy services for your health plan’s members. Claims submitted for sleep testing and therapy services performed on or after the effective date will not be paid if [prior authorization, or plan-specific term] has not been obtained through the AIM Sleep Management Program.
