DHS, MCO, and county Medicaid IT systems compared — system age, cloud adoption, and how IT quality drives fraud detection outcomes.

Technology Systems Summary

Minnesota spends $226 per enrollee on Medicaid IT — above the $195 national average — but ranks 42nd in cloud adoption and bottom-third for system modernity. Key systems: MMIS (claims processing), MAXIS (eligibility, 32 years old), and a rules-based fraud detection system from 2003. Two MCOs process claims on Microsoft Access and FileMaker Pro desktop databases.

Part of the Minnesota Medicaid Transparency Project — an independent, data-driven investigation of $23 billion in annual Medicaid spending across 87 counties.
