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Due to outdated provider licensing information, some providers did not receive proper notification of license expiration.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

Here's an answer to the question - "What's MES?"


Medicaid Enterprise System (MES)

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 which benefits our Members, Providers and stakeholders.  This collection of advanced technologies directly supports the business needs of DMAS.

MES - Why?

The Department of Medical Assistance Services (DMAS) planned and began building MES in 2016, to replace Virginia’s existing all-in-one-box solution.  DMAS followed the Centers for Medicare and Medicaid Services (CMS), who sponsored the Medicaid Information Technology Architecture (MITA) initiative.  MITA was designed to facilitate the nationwide upgrade to State’s Medicaid systems to a flexible, modular form.
