We require prior authorization for certain services and procedures. In these cases, providers will submit clinical documentation and medical records demonstrating that the service or procedure is medically necessary.

Authorization requests based on provider status

Most authorization requests go through our Auth Request tool. Authorization requests submitted to Priority Health differ by provider and service type based on your contracting status. Learn more about the preferred submission methods based on your provider status below:

Services not included in the Auth Request tool:

  • Drug authorizations not related to an inpatient stay or home infusions - use the drug authorization request forms
  • Medicare pre-service organization determinations. The Centers for Medicare and Medicaid Services (CMS) rules require that all Part C (Medicare Advantage) plans - not providers - give a specific written notice to members if a service or item isn't covered. The process for getting this written notice of non-coverage from Priority Health is called requesting a pre-service organization determination (PSOD). Go to PSOD instructions.
