Effective January 1, 2020, the Indiana legislature passed a law that requires health care providers to submit, and health plans to accept, requests for most prior authorizations sent through a secure electronic transmission.


You can find out more about this this law by visiting the Indiana Legislature website and view the Indiana House Bill 1143 and the final statute Health Care Services Prior Authorization (IC 27-1-37.5-10)


We encourage you to register to start using the electronic portals for your prior authorization requests now. Starting early will give you time to learn to use the portals and become comfortable with them.


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 using the Availity portal. For more information about Availity, please visit our website at the Availity link on our provider webpage. Here you can learn about all of the services offered through the Availity portal, register to use Availity, and find out how to access training on Availity.
