Medicaid Management Information System (MMIS)

Georgia Medicaid Management Information System logo

The Georgia Department of Community Health's (DCH) Medicaid Management Information System (MMIS) is an integration of computer systems that work together to process Medicaid and PeachCare for Kids® claims and other pertinent information related to the management of the Medicaid and PeachCare for Kids programs.

The Georgia Medicaid Management Information System (GAMMIS) began operations on November 1, 2010. Since then, the MMIS team has implemented numerous state and federally mandated system changes, which have resulted in enhancements, modifications and maintenance that provide a better experience for all entities that interface with the system.

The GAMMIS team has also provided project oversight for the initiation and planning phases of several large federally mandated projects, including the conversion to 5010 transaction standards and ICD-10 code sets.

In addition, DCH streamlined the provider enrollment process with a single application for Medicaid and various care management organization participation.

The Future of GAMMIS

Moving forward, the GAMMIS team (including DCH and Hewlett-Packard Enterprise Services, HPES) will continue to support these projects for the design, development and implementation (DDI) phase. Project oversight for these additional initiatives will include resource management, project management and subject-matter expertise with the following deadlines:

  • Implemented the Medicaid Modified Adjusted Gross Income (MAGI) changes – January 1, 2014
  • ICD-10 – Delayed until no sooner than October 1, 2015

As the largest purchaser of health care in the state of Georgia, DCH recognizes the importance of continuity of payments to our valued health care providers. The GAMMIS system provides:

  • Real-time processing of claims weekly
  • On-demand claims status
  • Eligibility verification requests
  • Web-based service options
  • Web-based computer training availability
  • Remittance Advice (RA) Voucher access
  • Policy Change Updates

HPES will continue to make changes as required in GAMMIS. DCH will notify providers and other trading partners about these changes via GAMMIS Banner Messages, fax and email blasts.
