Reminder: Commercial Plan Appeals Process for 2020 eviCore® Adverse Determinations

March 18, 2021

As a reminder, for dates of service on or after Jan. 1, 2021, AIM Specialty Health® is the utilization management vendor for Blue Cross and Blue Shield of Texas (BCBSTX) commercial Prior Authorization (PA) requests that were formerly handled by eviCore Healthcare®. To assist providers with this transition, in December 2020, a notice appeared on the eviCore website to alert providers of the appeals run-out process, which will continue through April 2021.

If you submitted a PA (pre-service) request through eviCore and that request was denied or if eviCore conducted a post-service (post-claim) medical necessity review resulting in an adverse determination, your letter will instruct that peer-to-peer discussions and appeals must be requested through eviCore. Please note that, for these pre- and post-service adverse determinations, eviCore will continue to process peer-to-peer and appeal requests through April 30, 2021, only. After April 30, 2021, eviCore will redirect any peer-to-peer and appeal requests to BCBSTX.

The vendor that issued the pre- or post-service adverse determination will process any related peer-to-peer or appeals requests through April 30, 2021. For any adverse determination after Jan. 1, 2021, follow the instructions in the letter you receive from BCBSTX.
