Information about the Utilization Management Process

Ensuring Appropriate Service and Coverage

In conjunction with our health plan partners, IntegraNet Health is committed to covering our mutual plan members’ care and encourage appropriate use of healthcare services.  Physicians, providers and IntegraNet staff who make utilization-related decisions must comply with the following policies:

  • Utilization management decisions are based on appropriateness of care and services and existence coverage.
  • IntegraNet Health does not compensate physicians, providers, or other individuals conducting utilization review for denials of coverage or services.
  • IntegraNet Health does not provide financial incentives for utilization management decision-makers to encourage decisions that result in under-utilization.

Medical Director Calls (also called Peer-to-Peer)

The IntegraNet Health Medical Director will review cases where the potential for denial is raised during the pre-authorization review process.  In any instances where the medical necessity or appropriateness of the requested service is questioned by the Utilization Review Coordinator, or Health Plan, the UM Medical Director will make a reasonable effort to contact the requesting and/or attending provider to afford them the the opportunity to discuss the plan of treatment and the clinical basis for the decision, prior to a final determination.
