Effective January 1, 2021, the Missouri legislature passed a law that requires health plans to accept requests for prior authorizations sent through a secure electronic transmission. 


We encourage you to register to start using the electronic portals and HIPAA transactions to submit your prior authorization requests now. Anthem has multiple secure portals/transactions available for providers to submit prior authorization requests depending on the health service being provided.


  • Prior authorizations for medical and behavioral health services are submitted using the Availity portal. For more information about Availity, please visit our website at anthem.com/provider/availity/. 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.

  • AIM ProviderPortalSM. For services administered by AIM Specialty Health®, providers may submit electronic prior authorization requests to AIM using the AIM ProviderPortalSM directly at providerportal.com.

  • HIPAA Prior Authorization/Referrals 278 and Inpatient Admission and Discharge Notification 278N 5010 transactions functionality is coming soon.


You can find out more about this this law by visiting the Missouri Legislature website and view the Missouri House Bill 514.
