Which States Have the Most Medicaid Fraud?

How Minnesota compares to other states on Medicaid spending, fraud risk, and oversight — and what the national data reveals about systemic vulnerabilities.

Medicaid Fraud by State: What the Data Shows

Medicaid fraud is a national problem — the HHS Office of Inspector General estimates $100+ billion in improper payments annually across all states. However, fraud risk varies significantly based on each state's spending levels, oversight structure, and program design.

• States with higher per-enrollee spending tend to have greater fraud exposure
• Decentralized administration (like Minnesota's 87-county model) creates oversight gaps
• States that expanded Medicaid under the ACA saw increased enrollment and fraud risk
• Technology modernization correlates with better fraud detection outcomes

Where Does Minnesota Rank?

Minnesota has several characteristics that elevate its fraud risk compared to other states:

• #5 nationally in per-enrollee Medicaid spending at $11,829
• #1 nationally in per-enrollee disability spending at $57,900
• 87 county administration — more fragmented than most states
• 17-year-old mainframe processing $14.3B in claims
• 26 states have modernized Medicaid IT since 2018 — Minnesota has not

Spending Comparison: Minnesota vs Peer States

What Makes Some States More Vulnerable?

• Higher spending per enrollee creates larger targets for fraud
• Fragmented county-level administration reduces centralized oversight
• Older IT systems cannot detect billing anomalies in real time
• Rapid program growth without matching oversight expansion
• High reliance on managed care without adequate contract monitoring
