National Imaging Associates (NIA)

Advanced Diagnostic Imaging

Iowa Total Care has contracted with National Imaging Associates Inc. (NIA), an affiliate of Magellan Health Services, for radiology benefit management.

The program includes management of non-emergent, high-tech, outpatient radiology services through prior authorization. This program is consistent with industry-wide efforts to ensure clinically appropriate quality of care and to manage the increasing utilization of these services.

Iowa Total Care oversees the NIA program and is responsible for claims adjudication. NIA manages non-emergent outpatient imaging/radiology services through contractual relationships with free-standing facilities.

Prior authorization is required for the following outpatient radiology procedures:

  • PET Scan

Cardiac Solutions

Iowa Total Care, in collaboration with NIA Magellan, will launch a cardiac imaging program to promote health care quality for patients with possible cardiac disease. 

Under this program, Prior Authorization will be required for certain cardiac studies to determine if the cardiac test or procedure is the most appropriate next step in a patient’s diagnosis or treatment—and to recommend an alternate approach when indicated. By supporting the most efficient diagnosis and management of cardiac disease, NIA Magellan addresses unnecessary procedures and promotes the least invasive, most medically appropriate approach.

Prior Authorization is required for the following cardiac procedures through NIA/Magellen:

  • Myocardial Perfusion Imaging (MPI)
  • MUGA Scan
  • Echocardiography
  • Stress Echocardiography


Providers rendering the above services should verify that the necessary authorization has been obtained. Failure to do so may result in non-payment of your claim.

Provider education material is located on the NIA website.  Educational resources include quick reference guides, tip sheets, frequently asked questions, and a recorded Webinar that outlines how to submit a prior authorization.
