Attention Providers:

Due to outdated provider licensing information, some providers did not receive proper notification of license expiration.  This may affect your ability to perform tasks in the PRSS portal.  If you recently received a License Expired Termination Notification, you DO NOT NEED TO TAKE ACTION.

We are working expeditiously to reinstate all terminated service locations by early next week.  A future notice will be sent to you requiring your updated licensing information to be submitted for continued enrollment.

If you have any questions please send them to

Welcome to the MES Provider Resource area!

This is the new location for Provider information and resources.   The information resources on the legacy Medicaid portal are no longer available, but don’t worry - we’ve got you covered!   Links to all of the Medicaid Memos, Bulletins, Forms and Manuals have been updated and are available below.   MES will continue to provide the same resources you need to get your job done, and help provide for our Members' health care.

What is MES?

The Medicaid Enterprise System (MES),  pronounced 'Mez, was created to transform our Medicaid technology from an antiquated all-in-one-box solution, to a modular, expandable and cost-effective solution.  This collection of advanced technologies directly and efficiently supports the business needs of DMAS and our Providers.

MES - Getting Started as a Provider


We have some great new training resources for Providers, covering all aspects of the new PRSS portal (includes MCO courses).  Also, CRMS users have their own training resources for LOCERI, PACE and eMLS.

Where do I go from Here?

Start your journey to the new PRSS portal by reviewing the training curriculum and choosing the courses for you.  Providers will need to login to the MES secure portal with their new MES credentials after April 4.

Don't forget to check our updated Provider FAQ for answers to many popular questions about MES affecting Providers like you.
