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.


Start using the electronic portals now

We encourage you start using the electronic portals for your prior authorization requests now. You do not have to wait until January 2020. 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.
