Physicians Pre-Authorization (1 of 3)Subject: Pre-Authorization Service for High-Tech Radiology Services

Diagnostic Imaging Associates has implemented a “Pilot Program” for Pre-Authorization Service for our Referring Provider Community.  This program applies to computerized tomography (CT), computed tomography angiography (CTA), magnetic resonance imaging (MRI), magnetic resonance angiography (MRA), and nuclear cardiac imaging studies. 

Please note:  We are not able to do stat requests due to the nature of the questions asked.  They are best handled with the patient’s full chart and referring doctor at hand.
If your patient needs services that require preauthorization/notification, complete our preauthorization request form and fax it to us at (302) 292-0204 along with the clinical information necessary to complete the request.  Keep in mind that all clinical information should be completed on our form clearly and concisely.  Our Diagnostic Imaging Pre-Authorization Representative will:

  • Verify eligibility and benefits
  • Obtain authorization
  • Schedule procedure at any of our DIA locations

If additional information is required or the form is not complete we will contact you for the necessary information.  Note; It may also be necessary to contact you for your assistance in interpreting some of the physicians notes.

Your office will be provided with the authorization number as well as your patient’s scheduled appointment date, time, and location.

You will need to register for the Pre-Authorization Service by faxing the completed registration form to us at (302) 292-0204 and by providing your Marketing Representative with the original signed registration form.

Please contact our Pre-Authorization Service Specialist Michelle Connor at (302) 451-5667 or via email  You may also contact Kathie Giordano, Mgr. at (302) 451-5664 or via email for any questions you may have regarding authorization.
