Update on COVID-19


GOOD NEWS! NIA has implemented new functionality that makes it easier for CareSource providers to access the Web site. Beginning Jan. 30, 2010, providers can access RadMD directly from the CareSource provider Web site. This means that users coming from the CareSource site no longer have to sign in again when they are directed to NIA's RadMD site.

Effective 1/1/18, in addition to the management of MR, CT and PET, prior authorization will be required for the following cardiac procedures for ONLY CareSource OH Exchange, Medicare, Medicare Advantage, ABD Adults and MAGI members as well as CareSource KY, WV and IN Exchange. 

  • Myocardial Perfusion Imaging (MPI)
  • MUGA Scans
  • Echocardiography (Transthoracic and Transesophageal Echocardiography)
  • Stress Echocardiography

Note:  The above cardiac procedures will NOT require prior authorization for Ohio CFC and ABD Kids and Indiana and Georgia Medicaid members.
