In 2018, 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.


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