For Medicaid audits sponsored by the Centers for Medicare and Medicaid Services (CMS), a Medicaid Integrity Contractor (MIC) is used.

Medicaid Integrity Contractors (MMICs) work out of five jurisdictions:

  • New York (CMS Regions I & II)
  • Atlanta (CMS Regions III & IV)
  • Chicago (CMS Regions V & VII
  • Dallas (CMS Regions VI & VIII)
  • San Francisco (CMS Regions IX & X)
