This process, which began in 2023 and is expected to continue into 2025, is leaving many vulnerable populations without the health coverage they relied on for years. The implications are far-reaching, as the number of uninsured Americans may rise dramatically in the coming months, with profound consequences for both public health and the economy.
The Medicaid Unwinding Process: A Hard Hit to Vulnerable Populations
The most recent figures from the Centers for Medicare and Medicaid Services (CMS) show that Medicaid enrollment has steadily declined since March 2023, when states were permitted to begin disenrolling individuals who had gained coverage during the COVID-19 pandemic. At the start of 2025, Medicaid had about 72 million enrollees. By July 2025, that number had dropped to 70.3 million, a decrease of roughly 1.6 million.
This process is part of an effort to reverse the emergency measures put in place under the Biden administration, which expanded access to Medicaid in several states. During the pandemic, Medicaid enrollment grew significantly, reaching an all-time high of 87 million in March 2023. However, under federal law, states could only start removing people from the rolls after the health emergency ended. This “unwinding” process is expected to continue throughout 2025, with even more individuals losing coverage as states process disenrollments.
This shift is particularly concerning for low-income Americans, many of whom have become accustomed to Medicaid’s financial protection. Experts have warned that the abrupt reduction in coverage could lead to a surge in the number of uninsured individuals, especially those who find themselves unable to afford private insurance or who don’t qualify for other forms of government assistance.
Lindsey Leininger, a professor at Dartmouth College, explains to Newsweek that “the churn in and out of coverage” creates significant disruptions in care. Patients who are forced to switch plans due to disenrollment might find it difficult to maintain their medical providers or access the medications they need. This is particularly concerning for those with chronic conditions or special needs who depend on the continuity of care that Medicaid has traditionally provided.
Long-Term Impacts: Work Requirements and Medicaid Cuts
Adding another layer of complexity to this situation are the proposed changes under President Trump’s administration. His administration’s “One Big Beautiful Bill” seeks to implement around $1 trillion in cuts to Medicaid. According to the Congressional Budget Office (CBO), these cuts could push millions more off the program in the coming years.
Further complicating matters, the Trump administration is also seeking to implement stricter work requirements for Medicaid recipients. The goal is to ensure that only those who are working or meeting other eligibility criteria can remain on the program. However, experts like Paul Shafer, a professor at Boston University, argue that these requirements will increase “administrative burdens” for low-income individuals, making it even harder for them to stay covered.
Shafer warns that the combination of more frequent paperwork, strict eligibility checks, and the expiration of enhanced subsidies for Affordable Care Act (ACA) plans will likely push more Americans into the ranks of the uninsured. Without health insurance, many people will be forced to delay or forgo necessary medical treatments, leading to worsening health conditions and higher long-term healthcare costs.
The changes to Medicaid coverage are not occurring in a vacuum. The expiration of enhanced ACA tax credits in 2025 will also drive up premiums for individual plans. These premium hikes could put a greater strain on those already struggling financially, pushing them toward the margins of the healthcare system.
