Medicaid’s $33 Billion Question: A System at a Crossroads

By Michael Bennett

WASHINGTON, D.C. – August 04, 2026 – A bombshell report landed in Washington this week, alleging that the nation’s healthcare safety net for the poor is hemorrhaging taxpayer dollars. According to the Paragon Health Institute, a conservative-leaning think tank, nearly half of the 20.2 million Americans enrolled in the Affordable Care Act's (ACA) Medicaid expansion were likely ineligible in 2024. The price tag for this alleged error? A staggering $32.9 billion in federal funds, just for one year.

The findings, authored by economist Liam Sigaud, were strategically released as Paragon’s president, Brian Blase, testified before the Senate Budget Committee. "Medicaid resources are not unlimited," Blase, a former healthcare policy advisor in the Trump administration, told lawmakers. "Every dollar spent on someone who is not eligible is a dollar unavailable for children, pregnant women, seniors, and people with disabilities."

Paragon’s research paints a picture of a system rife with misaligned incentives and lax oversight, particularly singling out states like California for allegedly racking up over $10 billion in improper federal spending. But as with any multi-billion-dollar government program, the story is more complex than a single headline. The report ignites a crucial debate not just about fiscal responsibility, but about the very design and future of America's healthcare contract with its most vulnerable citizens.

The Anatomy of a Mismatch

To understand the core of Paragon’s argument, one must look at the financial architecture of the ACA itself. The law incentivized states to expand Medicaid to cover nearly all adults with incomes up to 138% of the federal poverty level. The lure was powerful: the federal government promised to pay 90% of the cost for this new expansion population, a far more generous deal than the roughly 50-77% federal match for traditional Medicaid beneficiaries like children and the disabled.

Paragon argues this created a perverse incentive. "Congress designed Medicaid expansion so Washington pays at least 90 percent of the cost, giving states weak incentives to ensure eligibility is determined accurately," Blase stated. In essence, it’s cheaper for a state to have an individual classified as an “expansion” enrollee than a “traditional” one. The report estimates that states saved nearly $7 billion in 2024 by misclassifying beneficiaries who should have been in the traditional category into the higher-reimbursement expansion group.

This isn't just about accounting; it's about strategic behavior. For state budget officers, maximizing federal dollars is a primary directive. When faced with a complex eligibility case, the path of least financial resistance for the state is clear. This structural flaw, critics argue, has turned a program meant for targeted support into a fiscal shell game where states offload costs onto federal taxpayers. The numbers have ballooned, with Paragon estimating a near-doubling of improper enrollees from 4.9 million in 2019 to 9.2 million in 2024.

A System Under Stress

While Paragon’s analysis points to flawed incentives, it unfolds against the backdrop of a system in unprecedented turmoil. The COVID-19 pandemic triggered a “continuous enrollment” provision, pausing all Medicaid eligibility checks for over three years. When this provision ended in 2023, states began the monumental task of “unwinding”—re-evaluating the eligibility of over 90 million people.

The process has been chaotic. According to data from the Kaiser Family Foundation (KFF), over 25 million people have been disenrolled from Medicaid as of mid-2024. Crucially, a large percentage of these disenrollments—two-thirds in a state like California—were for “procedural reasons,” not because the person was confirmed to be ineligible. People lost coverage because a renewal form was sent to an old address, a document was lost, or they couldn't navigate a complex bureaucracy in time.

This context adds a critical layer of nuance to the term “improper enrollment.” Health policy experts from more progressive organizations argue that focusing solely on income-based ineligibility misses the larger story of administrative failure and the risk of stripping coverage from people who still qualify. "The complexity of Medicaid eligibility rules and the sheer administrative burden on states can lead to errors even with diligent efforts," one health policy analyst noted. The unwinding has revealed that state IT systems and staffing levels are often inadequate for the task, a problem that contributes to both wrongful disenrollments and the potential for ineligible individuals to remain on the rolls.

The Price of a Safety Net

Brian Blase’s argument that improper spending harms the truly needy is emotionally resonant and forms the ethical core of Paragon’s critique. But the evidence that expansion enrollment directly diverts resources from traditional beneficiaries is debated. Federal funding streams for the two groups are largely distinct due to the different matching rates. Advocates for expansion argue it strengthens the entire healthcare ecosystem.

By reducing the number of uninsured patients, expansion lowers the uncompensated care costs that burden hospitals and clinics, theoretically stabilizing the healthcare environment for all patients, including traditional Medicaid recipients. Furthermore, some analyses suggest that expansion has led to no significant negative impact on access to care for traditional populations. "The focus should be on ensuring all eligible individuals, regardless of category, receive coverage," commented an advocate for a patient rights group. "Fixing administrative errors shouldn't mean dismantling a program that has provided a lifeline to millions."

The debate highlights a fundamental tension in social program design: how do you balance broad access and ease of enrollment against the need for rigorous fiscal stewardship? For the 2026 consumer—or in this case, the citizen-as-consumer of government services—the experience is one of confusion, anxiety, and a system that feels both essential and deeply flawed.

The Path Forward: Reform or Repair?

Washington is already responding, though perhaps not in the way Paragon fully envisions. The institute advocates for dramatic reforms, such as lowering the federal match rate for the expansion population to remove the state-level incentive. Such a move would be politically explosive, facing fierce opposition from the nearly 40 states that have adopted expansion.

Instead, recent legislative and administrative actions are focused on tightening the screws. The “One Big Beautiful Bill Act,” enacted in 2025, mandates that states begin redetermining eligibility for expansion adults every six months instead of annually, a change projected to reduce enrollment significantly. Concurrently, the Centers for Medicare & Medicaid Services (CMS) is cracking down. In April 2026, the agency launched a “Medicaid Fraud War Room” that it claims stopped over $200 million in improper payments in its first three months. A month later, it proposed sweeping new rules to rein in state payment practices, aiming for over $500 billion in federal savings over the next decade.

These measures suggest that policymakers recognize the program's integrity challenges. The question is whether these incremental repairs are enough to fix a system that, according to Paragon’s data, may have a multi-billion-dollar structural flaw at its core. As states continue to navigate the post-pandemic landscape, the tension between ensuring access and enforcing accountability will define the future of America’s largest health insurance program.
