MMIS Provider Codes

MMIS, or Maintenance Management Information System, is a mechanized claims processing and information retrieval system for Medicaid that's required by the federal government. All states are required to operate an MMIS to support Medicaid business functions and maintain information in such areas as provider enrollment; client eligibility, including third party liability; benefit package maintenance; managed care enrollment; claims processing; and prior authorization. A fiscal agent who is a private contractor to the state, normally selected through a competitive procurement process, may operate the state's MMIS source.

The descriptions for these codes must be used:
