As we have communicated in recent newsletters, the Indiana legislature passed House Bill 1143 which, among other things, requires health care providers to submit, and health plans to accept, requests for most prior authorization requests through a secure electronic transmission beginning for requests sent on and after January 1, 2020.


You are now required to use the secure electronic portals for your prior authorization requests.


Anthem has multiple secure electronic transmission portals available for providers to submit prior authorization requests depending on the type of health service being provided.


  • Availity. Prior authorizations for medical and behavioral health services are submitted through the Interactive Care Reviewer (ICR) using the Availity portal at To access ICR, log in to the Availity portal then select Patient Registration > Authorizations and Referrals > Authorizations. To learn more about ICR, go to and view links to on demand learning modules or register for the next live ICR webinar.


  • AIM ProviderPortalSM. For services administered by AIM Specialty Health®, providers may submit electronic prior authorization requests to AIM using the AIM ProviderPortalSM directly at The AIM portal can also be accessed through the Availity portal at Log in to the Availity portal, then Patient Registration > Authorizations and Referrals > AIM Specialty Health.
