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.  Users with MES credentials, can use the blue login button at the top of any page to login to the secure portion of MES to access the modules you are authorized for (like PRSS and CRMS).  You can ask your manager about getting access to MES modules.
