Utilization management (UM)

We use evidence-based clinical practice guidelines when making decision about members’ care.

Clinical practice guidelines address preventive, acute or chronic and behavioral health services. These guidelines are reviewed at least every two years and updated as necessary. When this happens, we notify all network practitioners.

When determining the medical appropriateness of a service, we apply these criteria while taking into account individual circumstances and the local delivery system.

Clinical and UM staff make decisions based solely on appropriateness of care and existence of coverage. We do not reward staff for issuing denials of coverage. We do not encourage under utilization by providing financial incentives to deny coverage.
