State Directed Payments in Medicaid vary from $0 to $4,761 per beneficiary across states, allowing some jurisdictions to shift program costs onto federal taxpayers and ultimately onto residents of other states, according to a new report published this week by the Competitive Enterprise Institute. The analysis, submitted as a comment to the Centers for Medicare & Medicaid Services, supports proposed regulations that would cap these payments under limits established by a recent budget law. The report argues that State Directed Payments, often combined with provider taxes or intergovernmental transfers, have transformed Medicaid from a state-federal partnership into a mechanism for interstate cost redistribution.

The report details sharp geographic disparities in how states use these payment arrangements. Mississippi leads the nation with the highest State Directed Payments per Medicaid enrollee, while northeastern states, many Great Plains states, and Florida, Alabama, and Alaska all register among the lowest users. The range spans from zero dollars to $4,761 per beneficiary, with wide variation across the country. Under Medicaid's traditional funding formula, some states receive three federal dollars for every state dollar they spend, while others receive only one dollar for the same expenditure. For populations covered under the Affordable Care Act expansion—those not previously eligible for Medicaid—the federal government contributes nine dollars for every state dollar spent, a disparity that shapes how aggressively states pursue these payment strategies.

The report finds that federal reimbursement policies encourage Medicaid expansion, create divergent incentives across states based on their matching rates and expansion decisions, and make program outcomes dependent on state administrators' ability to exploit financial workarounds. According to the analysis, provider taxes paired with State Directed Payments function as one such workaround. Before the Affordable Care Act, Medicaid funding was driven primarily by the standard matching formula, and many states chose to cover only specific groups such as mothers with children, children, and disabled individuals, up to income limits below the poverty line. The law's expansion option, with the federal government covering 90 percent of costs for newly eligible enrollees, led 41 states to broaden coverage to everyone up to 138 percent of the federal poverty level.

The report explains that economic theory predicts consumers will demand more of a service when they contribute fewer resources to obtain it. Applied to Medicaid, the analysis argues, states that paid the full cost of their benefits would exercise greater care and prudence with spending, monitor fraud and eligibility more closely, and focus the program more narrowly on those with the greatest need. Instead, the current system creates what the report calls fiscal externalities—costs borne by parties outside the transaction. When states use provider taxes and directed payments to draw down additional federal funds, they're not simply increasing Medicaid spending; they're engineering a transfer from taxpayers in states that use these mechanisms less aggressively.

The report supports the proposed CMS rule implementing limits on State Directed Payments as a step toward curbing this interstate cost-shifting. By capping these payments, federal regulators would reduce states' ability to exploit the gap between their own spending and federal reimbursement, potentially slowing the growth of Medicaid expenditures and limiting the extent to which some states can export their program costs to others. The bottom line: Medicaid's financing structure has evolved into a system where strategic use of payment mechanisms matters as much as medical need in determining program scope and cost.
