Loss of Automatic Reenrollment Causes Drop in Health Insurance Coverage: A recent study published in JAMA Health Forum by researchers from the University of Pittsburgh, University of South Carolina, and Emory University reveals a concerning trend: the removal of automatic reenrollment for zero-premium health insurance plans has led to a significant decline in coverage among low-income Americans. Drawing on data from 2022 through 2024, the researchers found that around 250,000 individuals likely lost their Marketplace insurance and became uninsured in 2024. This phenomenon highlights the vital role of policy design in maintaining insurance coverage for vulnerable populations.
The Affordable Care Act (ACA), since its inception, has enabled millions of previously uninsured Americans to gain access to affordable healthcare coverage via HealthCare.gov. This effort was further strengthened by the American Rescue Plan (ARP) and the Inflation Reduction Act (IRA), which broadened the availability of zero-dollar premium plans for those earning less than 175% of the federal poverty level. For reference, in 2025, this income threshold equates to approximately $27,000 for individuals and $56,000 for a family of four. However, the elimination of automatic reenrollment into these plans has inadvertently undermined this progress.
The study examined 36.7 million HealthCare.gov enrollees across 29 states over three years, tracking changes in plan enrollment and coverage continuity. When insurers exited the Marketplace, enrollees were defaulted to new plans, but the absence of automatic reenrollment into zero-premium options meant many were left without coverage unless they actively chose a new plan. This administrative barrier, though seemingly minor, had a disproportionate impact on low-income individuals who are already navigating a complex healthcare system.
Who Can Apply for HealthCare.gov Insurance?
Individuals and families residing in the United States who are not eligible for Medicaid or employer-sponsored health insurance can apply through HealthCare.gov. Eligibility primarily depends on income, household size, and immigration status. To qualify for subsidies or zero-premium plans, applicants must:
- Be a U.S. citizen or lawfully present immigrant
- Not qualify for Medicaid, Medicare, or other public health insurance programs
- Have a household income between 100% and 400% of the federal poverty level (FPL)
For zero-premium plans, income must be below 175% of the FPL, translating to approximately:
- $27,000 for an individual
- $56,000 for a family of four
Health Insurance Fees and Premiums
The cost of health insurance through HealthCare.gov varies based on the plan selected, location, age, and income level. Thanks to subsidies, many low-income individuals pay very low or even zero-dollar monthly premiums. The types of costs include:
- Premiums: Monthly fees for the insurance plan
- Deductibles: Amount paid out-of-pocket before insurance coverage kicks in
- Co-payments/Co-insurance: Share of costs for covered services
- Out-of-pocket maximums: Limit on total expenses in a year
With ARP and IRA in effect, zero-dollar premium plans have become more accessible, reducing financial barriers to enrollment. However, loss of automatic reenrollment jeopardizes these gains by requiring proactive action from enrollees each year.
How to Use and Benefit from Health Insurance
Once enrolled in a HealthCare.gov plan, individuals can access a wide array of healthcare services including:
- Primary and preventive care (check-ups, vaccinations, screenings)
- Specialist consultations
- Emergency room services
- Prescription medications
- Mental health support
Using the insurance efficiently involves understanding your plan’s network, benefits, and cost-sharing structure. Routine care should be scheduled within network providers to avoid additional costs. Moreover, preventive services are typically covered at no extra cost, enabling early diagnosis and treatment.

Loss of Automatic Reenrollment Causes Drop in Health Insurance Coverage Conclusion
The recent study underscores how minor policy shifts, such as removing automatic reenrollment into zero-premium plans, can have major repercussions on health insurance coverage rates. This administrative hurdle has potentially left a quarter million people without coverage, reversing progress made under the ACA and recent affordability-focused legislation.
Zero-premium plans have proven to be a lifeline for low-income households, making it essential to maintain policies that simplify access and continuity of care. Reintroducing automatic reenrollment could be a vital step in improving retention rates and safeguarding the health of America’s most vulnerable populations.
Moving forward, policy makers must weigh the unintended consequences of administrative changes, especially when they disproportionately impact those with fewer resources and less access to information or assistance.
Ultimately, maintaining high coverage rates not only benefits individual health outcomes but also strengthens the broader healthcare system by spreading risk and reducing uncompensated care costs.
Loss of Automatic Reenrollment Causes Drop in Health Insurance Coverage FAQs
1. Why is automatic reenrollment important for Marketplace insurance?
Automatic reenrollment ensures that enrollees maintain continuous coverage even if they forget or are unable to manually reenroll. This is particularly crucial for low-income individuals who may face technological, educational, or language barriers when navigating HealthCare.gov.
2. What are zero-premium plans and who qualifies for them?
Zero-premium plans are health insurance policies with no monthly premium cost. Under the ARP and IRA, individuals earning below 175% of the federal poverty level often qualify for these plans, which significantly reduce the financial burden of maintaining health coverage.
3. What happens if my insurer leaves the Marketplace?
If your insurer exits the Marketplace, you may be automatically matched to a similar plan. However, without automatic reenrollment into a zero-premium option, you might be placed into a plan with a premium, requiring you to manually switch to a more affordable plan or risk losing coverage.
4. How can I find out if I qualify for subsidies or a zero-premium plan?
You can use the subsidy calculator on HealthCare.gov or KFF’s interactive tool to estimate your eligibility based on income and household size. During the application process, the platform will also automatically assess your subsidy eligibility.
5. Can I apply outside of the Open Enrollment Period?
Yes, you can apply during a Special Enrollment Period if you experience a qualifying life event such as losing job-based coverage, getting married, having a baby, or moving to a new state. Documentation may be required to verify your eligibility for SEP.
