As previously announced, Fidelis care is pleased to share we are expanding our partnership with National Imaging Associates, Inc. (NIA) to provide utilization management for outpatient rehabilitative and habilitative physical medicine services for Fidelis Care’s Medicare members. This expansion builds on Fidelis Care’s current prior authorization program for physical medicine services being provided to their Medicaid and Qualified Health Plan members. The program is consistent with industry-wide efforts ensuring that physical medicine services provided to our members are consistent with nationally recognized clinical guidelines.

All providers will be required to obtain prior authorization for physical therapy, occupational therapy, and speech therapy services rendered in an outpatient or home-based setting on and after October 1, 2021.  The NIA Call Center and www.RadMD.com will be available beginning September 20, 2021, for prior authorization for dates of service October 1, 2021 and beyond.
