Prior Authorization Submission Enhancements

The following enhancements have been made to the Prior Authorization and Notification (PAAN) tool on Link:

  • Outpatient facility case requests are changing from a single date of service to an automatic 90-day service period. You no longer have to call to change the date as long as it falls within the 90-day service period. 
  • Enhanced functionality is now available to support adding attachments in the new prior authorization experience.   
  • For standard medical prior authorizations, we have enabled an integrated screen experience which addresses any pop-up blocker issue.

In 2020, we’ll continue to add additional prior authorization service categories. Please access the Interactive Guide for PAAN Tool found at for the latest service category launch dates, system functionality and training.
