Effective for dates of service on or after April 1, 2021, this program also applies to U.S. Family Health Plan members.

The following services require prior authorization through NIA’s High-Tech Imaging program. Ordering providers must obtain authorization before requesting outpatient high-tech imaging services. Depending on the member’s plan, providers must contact either NIA or Cigna.

  • CT/CTA scans
  • MRI/MRAs
  • PET scans
  • Nuclear cardiology

Requests meeting clinical criteria will be assigned an authorization number.

For non-approved authorizations, a nurse may request additional information, or forward the request to a physician reviewer. The physician reviewer will either approve, request additional information, or deny the service request. 

For a list of procedure codes subject to prior authorization by NIA, refer to the High-Tech Imaging and Cardiac Program Prior Authorization Code Matrix.
