Advanced Imaging

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

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

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

    The following imaging services are subject to review:

    • Computerized tomography (CT)
    • Magnetic resonance imaging, angiography (MRI/MRA)
    • Nuclear cardiology
    • Echocardiography (ECHO)
    • Positive emission tomography (PET)

      • 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.
