The Medicaid Enterprise Systems Community is a national community for state, federal and private sector individuals to exchange ideas related to Medicaid systems and health policy affected by those systems. Each year, it culminates in the Medicaid Enterprise Systems Conference. Both Community and Conference are organized by the New England States Consortium Systems Organization (NESCSO).

The Medicaid Enterprise Systems Conference (MESC) has been in existence since the 1990s and has grown to an attendance to over 1,600 attendees. States volunteer to host the event and work with a committee of federal, state and private sector individuals to plan and execute the conference. This committee identifies the main subject tracks and priority themes for the agenda covering a wide range of topics critically important to Medicaid programs. These have included Medicaid Enterprise System procurement, funding, and operations; modularity initiatives, as well as health information technology (HIT), health information exchange (HIE), and data analytics.

Exhibitors at the conference include large and small companies involved in Medicaid systems. With well over 100 exhibitors, the MES Conference provides a great way to learn about the latest offerings in Medicaid enterprise systems. In addition to exhibit space, various sponsorship opportunities are offered to exhibitors to provide them with access to potential customers.

The Centers for Medicare and Medicaid Services (CMS) participate and offer sessions on their current initiatives related to the Medicaid Information Technology Architecture (MITA); as well as other innovation initiatives. The MES Community also has year-round working groups dedicated to tackling particular problems faced by the MES sector.
