Understanding Medicaid's Enrollment Crisis: Implications for Benefits Advisors
A new study reveals that nearly half of Medicaid’s expansion enrollees may be ineligible, leading to a $32.9 billion federal cost in 2024. This situation poses significant challenges for insurance brokers and benefits advisors as they navigate the complexities of employer coverage.

In the labyrinth of American healthcare, Medicaid has long served as a crucial safety net for low-income individuals and families. However, recent research has unveiled a staggering reality: approximately 9.2 million individuals enrolled in Medicaid's expansion program may not meet eligibility requirements. This improper enrollment has resulted in a hefty federal cost of $32.9 billion in 2024 alone. As a benefits advisor or insurance broker, understanding the implications of this crisis is critical, not just for compliance but for the broader health insurance landscape.
The enrollment crisis reveals not only a systemic failure in ensuring that Medicaid serves its intended population but also a ripple effect that impacts employer-sponsored insurance and private market pricing. With the integrity of Medicaid's enrollment rolls in question, benefits advisors face an increasingly complex environment when making coverage decisions for their clients.
The Roots of the Enrollment Crisis
The issues surrounding Medicaid’s enrollment can be traced back to the structure of its financing under the Affordable Care Act (ACA). The ACA incentivized states to expand Medicaid by offering a significantly higher federal match for expansion enrollees—90% compared to around 60% for traditional enrollees. This financial structure has created a misalignment of incentives that encourages states to enroll individuals who may not qualify under the program's current guidelines.
Impact of COVID-19 on Enrollment
The COVID-19 pandemic exacerbated eligibility checks as a continuous coverage requirement was enacted, preventing states from conducting necessary eligibility verifications from March 2020 until May 2023. Consequently, as states began the unwinding process, the number of expansion enrollees did not return to pre-pandemic levels, remaining 21% higher than before the crisis.
- 2024 Improper Enrollment Figures: 9.2 million individuals
- Cost to Federal Government: $32.9 billion
- Improper Enrollment Growth: From 4.9 million in 2019 to 9.2 million in 2024

Legal and Financial Consequences
The implications of improper enrollment extend beyond financial misalignment; they also invite legal scrutiny. A notable case in Massachusetts against UnitedHealthcare highlights the potential for legal repercussions surrounding Medicaid payments. With approximately one-third of ineligible expansion enrollees qualifying for Medicaid through other pathways, states may be strategically misclassifying individuals to benefit from higher federal matches.
The California Case Study
California stands out in this crisis, accounting for 3.1 million improper enrollees and over $10 billion in federal costs in 2024. With an improper enrollment rate soaring to 62%—up from 45% in 2019—the state illustrates how financial incentives can lead to significant misclassification. The disparity in federal matching rates for traditional and expansion enrollees creates a strong financial lure for states to prioritize expansion enrollments.
Implications for Benefits Advisors and Employers
For benefits advisors, the current landscape poses a challenge in effectively interpreting Medicaid eligibility data. The traditionally reliable enrollment signals are now muddied, complicating risk pool assessments and pricing strategies for private market insurance. Many improper enrollees likely have incomes exceeding 138% of the federal poverty level or access to affordable employer coverage, meaning they represent a population that the employer market could potentially serve.
Duplicative Enrollment Concerns
Another layer of complexity arises from duplicative enrollment—when individuals are simultaneously covered by both Medicaid and employer-sponsored insurance. State Medicaid agencies often lack insight into enrollees’ private health coverage, leading to potential gaps in care. Advisors must be proactive in encouraging employees to clarify their coverage status with state Medicaid agencies to ensure compliance with federal Medicaid coordination of benefits guidance.

Legislative Attempts for Reform
While some legislative measures, like the One Big Beautiful Bill (OBBB), introduced reforms such as six-month redeterminations for expansion adults and penalties for states with high error rates, experts argue that these efforts fall short of addressing the root cause of the enrollment crisis. The persistent financial incentive for states to misclassify enrollees remains a central issue.
Equalizing Federal Match Rates
There is growing support in Congress to equalize the federal match rates between expansion and traditional enrollees. This change could potentially realign state incentives towards greater accountability in managing Medicaid enrollments. However, resistance from governors and state legislators—who are reluctant to forfeit substantial federal funding—poses a significant barrier to reform.

Key Takeaways
- 9.2 million: Estimated number of individuals improperly enrolled in Medicaid expansion.
- $32.9 billion: The federal cost attributed to improper enrollment in 2024.
- California: The state with the highest number of improper enrollees and costs.
- Incentive Misalignment: States benefit financially from misclassifying enrollees, complicating coverage decisions.
- Advisors' Role: Benefits advisors must navigate a more complex environment as Medicaid eligibility data becomes less reliable.
Frequently Asked Questions
What are the eligibility requirements for Medicaid expansion?
Medicaid expansion typically requires individuals to have incomes at or below 138% of the federal poverty level, but specific eligibility can vary by state. It is essential for potential enrollees to check their state’s guidelines to determine if they qualify. Additionally, Medicaid is designed to cover a range of vulnerable populations, including low-income adults, children, pregnant women, and individuals with disabilities.
How does improper enrollment affect the healthcare market?
Improper enrollment distorts the risk pools that insurance companies rely on to set premiums and design benefits packages. When individuals who do not qualify for Medicaid are included in the rolls, it creates an inaccurate representation of the population's health status, leading to potentially inflated costs for employers and private insurers.
What should benefits advisors do if they suspect duplicative enrollment?
Advisors should encourage employees to verify their coverage status with their state Medicaid agency, especially if they are enrolled in both Medicaid and an employer-sponsored plan. This proactive approach ensures compliance with federal guidelines and helps clarify which plan should act as the primary payer for healthcare services.
Are there any ongoing legislative efforts to address the enrollment crisis?
Yes, there are ongoing discussions in Congress about reforming the federal match rates to equalize funding between expansion and traditional Medicaid enrollees. While some reforms have been introduced, significant political resistance remains, making comprehensive change challenging. Benefits advisors should stay informed about legislative developments that could impact Medicaid enrollment and overall market dynamics.
