Projected Surge in Uninsured Americans: New Law and Expiring Credits Fuel Coverage Losses
Table of Contents
Washington D.C. – A sweeping budget reconciliation package signed into law by President trump on July 4, 2025, is poised to substantially reshape the landscape of health insurance coverage in the United States. The Congressional Budget Office (CBO) estimates this legislation, coupled with the impending expiration of enhanced Affordable Care Act (ACA) premium tax credits, will lead to a ample increase in the number of uninsured Americans – exceeding 14 million by 2034.
Key Findings from the CBO Analysis
the CBO’s analysis reveals a projected 10 million increase in the uninsured population by 2034 due solely to the changes implemented by the new law. This figure breaks down as 7.5 million attributable to alterations in Medicaid and 2.1 million stemming from changes to the ACA Marketplaces, with an additional 0.4 million impacted by other policy adjustments. When factoring in the anticipated expiration of enhanced premium tax credits, the total number of uninsured is expected to surpass 14 million. These changes represent a meaningful shift in healthcare access for millions of Americans,
noted analysts at the CBO.
The impact of these changes will not be uniform across the country. Twenty states and the District of Columbia are projected to experience an increase in their uninsured rates by 3 percentage points or more. California and New York are expected to see the largest numerical increases, with 1.6 million and 860,000 additional uninsured residents, respectively. Florida, Texas, and Illinois will also face substantial increases, with 590,000, 480,000, and 470,000 more uninsured individuals, respectively.
Did You Know? The ACA Marketplace Integrity and Affordability rule, finalized earlier this year, is also expected to contribute to the rise in uninsured individuals, even though the CBO has not yet released specific estimates for its impact.
Medicaid Changes and State Responses
A major driver of the projected increase in uninsured individuals is changes to Medicaid policy, particularly the implementation of work requirements. The CBO estimates that Medicaid work requirements account for over half of the anticipated increase in the uninsured due to Medicaid changes. However, the actual impact will vary significantly depending on how individual states implement these requirements. Some states may adopt more lenient reporting procedures, while others may impose stricter standards, leading to a range of enrollment effects.
The CBO’s analysis highlights the uncertainty surrounding state responses to the new Medicaid policies. To account for this, the analysis presents a range of potential enrollment effects for each state, varying by plus or minus 25% from a midpoint estimate. This acknowledges that the ultimate impact will depend on the specific decisions made by state policymakers.
State-Level Impact: A Closer Look
The following table summarizes the projected increase in the uninsured rate by state, based on the CBO analysis:
| State | Projected Increase in Uninsured Rate (Percentage Points) |
|---|---|
| Alaska | 3.5 |
| Arizona | 3.2 |
| Arkansas | 3.1 |
| California | 3.0 |
| Connecticut | 3.3 |
| Delaware | 3.1 |
| Illinois | 3.0 |
| Indiana | 3.4 |
| Kentucky | 3.2 |
| Louisiana | 5.1 |
Pro Tip: Understanding the specific changes to Medicaid in your state is crucial for assessing your potential eligibility and coverage options.
The impending expiration of enhanced premium tax credits for ACA Marketplace enrollees further exacerbates the projected increase in the uninsured. Without these credits, many individuals and families will find health insurance less affordable, leading to a decline in enrollment. The CBO estimates that the combined effect of the new law and the expiring tax credits could result in increases in uninsured rates of at least 5 percentage points in Louisiana, Florida, and Arizona.
Do you think the expiration of these tax credits will disproportionately affect certain demographics or income levels?
Additional Factors and Ongoing Analysis
The finalized ACA Marketplace Integrity and Affordability rule is also expected to contribute to the rise in uninsured individuals. While the CBO has not yet released complete estimates for the rule’s impact, preliminary assessments suggest it could lead to an increase of between 725,000 and 1.8 million uninsured people in 2026. The rule’s provisions impacting enrollment processes are set to expire at the end of 2026, suggesting a potential decrease in coverage losses in subsequent years.
The CBO’s methodology involved allocating increases in the uninsured population based on factors such as changes in Medicaid, ACA marketplace adjustments, and interactions between different provisions. Population estimates were sourced from the Weldon Cooper Center for Public Service, assuming compound population growth.
Looking Ahead: Trends and Context
The ongoing debate surrounding healthcare access and affordability in the United States is deeply rooted in past trends and evolving policy landscapes. The ACA, enacted in 2010, represented a landmark effort to expand health insurance coverage, but it has faced ongoing challenges and political opposition. The recent legislative changes and the potential expiration of key subsidies signal a potential reversal of some of the ACA’s gains. Understanding these trends is crucial for policymakers, healthcare providers, and individuals alike as they navigate the complex world of health insurance.
