  • Prior authorization is required for certain procedures and services. Contracted providers are financially liable for providing services that are medically unnecessary. 

    Prior authorization is based on member benefits and eligibility at the time of service. It determines medical necessity, treatment appropriateness, and setting via nationally recognized guidelines.

    AIM Specialty Health (AIM) manages imaging services for Premera Blue Cross. Providers must make pre-approval requests through AIM for members on plans that require it.

    The following services are subject to review: 

    • CT scan
    • MRI/MRA
    • Nuclear Cardiology
    • Echocardiography (ECHO)
    • PET scan

    An order number isn't required for the following: 

    • Emergency room services
    • Inpatient hospitalization
    • Outpatient surgeries (hospitals and freestanding surgery centers)
    • 23-hour observations

    Diagnostic imaging services providers are strongly encouraged to verify that the pre-approval has been received before scheduling and performing diagnostic imaging exams. In addition, imaging providers must submit ordering/referring provider information, per guidelines from the Centers for Medicare and Medicaid Services (CMS), in boxes 17 and 17b on CMS-1500 forms.
