Evolent (formerly National Imaging Associates) ― Diagnostic Imaging Services
AmeriHealth Caritas Next has an agreement with Evolent, formerly National Imaging Associates, Inc. (NIA), to manage diagnostic imaging services such as MR/CT/PET.
The program will require prior authorization from Evolent for nonemergent outpatient:
-
CT/CTA
-
CCTA
-
MRI/MRA
-
PET scan
-
MUGA scan
-
Myocardial perfusion imaging (MPI)
The physician ordering the procedures noted above is responsible for obtaining prior authorization. The rendering facility must ensure that prior authorization was obtained.
We recommend that you develop a process to ensure that the appropriate authorization number(s) has been obtained. Payment to the ordering physician and rendering facility will be denied for procedures performed without necessary authorization.
Providers can request prior authorization via Evolent's RadMD tool or by calling Evolent at 1-800-424-4792.
