Submit your prior authorization requests online any time

Can you say convenience?  That’s what you get with Mississippi’s new online process for submitting Commercial prior authorization requests.

Behavioral health providers can now use the standard Mississippi online prior authorization form when requesting authorization of services. This applies for members covered by Commercial health plans for most levels of care.* The only exceptions are for inpatient, residential or partial hospitalization services. For those requests, continue to use the current process for those services.

The form is currently available for use. Beginning Jan. 1, 2027, all Mississippi providers are required to use the new standardized form, as outlined under Mississippi Senate Bill 2140.  

1. Access the prior authorization form on Providerexpress.com
2. Complete the form – be sure to fill in all fields marked mandatory
3. Submit the form – you should see a confirmation page after the successful completion

To request authorization for inpatient, residential or partial hospitalization

1. Log into the Provider Express secure portal with your One Healthcare ID and password
2. Select Auth Option from the menu
3. Choose Review Online
4. Complete the request
