A Coverage Cliff That Has Already Landed
On December 31, 2025, the enhanced premium tax credits (PTCs) that had made Affordable Care Act marketplace coverage affordable for tens of millions of Americans quietly expired. Congress did not extend them. For many enrollees, the first week of January 2026 brought a premium bill that had more than doubled overnight — and for millions, the only choice was to go without coverage entirely.
The Urban Institute now projects that 4.8 million Americans became uninsured in 2026 as a direct result of the subsidy expiration — a 21% increase in the national uninsured population. That estimate, developed by Senior Fellow Fredric Blavin and Principal Research Associate Michael Simpson, aligns closely with what a KFF follow-up survey conducted in late February and early March 2026 found: 9% of 2025 ACA Marketplace enrollees are now entirely without insurance.
Why This Matters
For people who lost coverage, the consequences are immediate and concrete. Without insurance, a routine doctor's visit, a prescription refill, or a single emergency room encounter can generate thousands of dollars in out-of-pocket costs. Chronic conditions that were previously managed through regular care may go unaddressed. Preventive screenings — for cancer, diabetes, heart disease, and more — are often the first services people skip when they lose coverage.
The Urban Institute's modeling projects that the rise in uninsured Americans will also produce a $7.7 billion increase in demand for uncompensated care in 2026 — costs that fall not on the federal budget but on hospitals, physicians, and state and local governments that absorb care for patients who cannot pay.
This is not a theoretical projection anymore. Millions of real people have already made the calculation and decided they could not afford coverage at the new rates.
What We Know So Far
The enhanced premium tax credits were first enacted through the American Rescue Plan in 2021 and extended under the Inflation Reduction Act. During that period, ACA enrollment more than doubled — from roughly 11 to 12 million enrollees in the years before the subsidies took effect to more than 24 million by 2025.
When the enhanced credits expired, premiums rose sharply. The KFF modeling put the average annual premium for subsidized enrollees at $1,904 in 2026, up from $888 in 2025 — a 114% increase in what households actually pay. For people with incomes below 250% of the federal poverty level, the Urban Institute projects that average net premiums are now more than four times as large as they were under enhanced credits — $919 per month compared to $169.
An additional 2.5 million Americans dropped ACA coverage but transitioned to other insurance — through employer plans or Medicaid — according to Jessica Banthin, a senior fellow in health policy at the Urban Institute and former deputy director for health at the Congressional Budget Office. Overall, the Urban Institute projected 7.3 million people would leave ACA marketplace coverage in 2026; of that group, 4.8 million would become uninsured while the rest found alternative coverage.
Where the Risk Is Highest
Eight states are projected to see their subsidized marketplace enrollment fall by more than half: Georgia, Louisiana, Mississippi, Oregon, South Carolina, Tennessee, Texas, and West Virginia. These states share a combination of higher baseline uninsured rates and particularly steep premium increases.
Texas faces the largest absolute increase in newly uninsured residents of any state, with a 39% projected rise. Florida projects a 29% increase in uninsured residents and approximately 1.08 million people leaving the marketplace. South Carolina projects a 50% increase in its uninsured population, which is among the steepest proportional increases in the country.
Nationally, the demographics most affected are non-Hispanic Black people, non-Hispanic White people, and young adults — groups that the Urban Institute projects will see the largest increases in uninsurance as a share of their population.
What Experts and Advocates Say
Jessica Banthin of the Urban Institute noted in January 2026 that the true impact of the lapsed subsidies "may be obscured" until midyear, as some households spend months attempting to find alternative coverage or deferring the decision entirely. That midyear picture is now coming into focus, and it closely matches what the projections anticipated.
Dr. Vin Gupta, a pulmonologist and health policy commentator, described the financial risk for people who chose to forgo coverage: the risk of an unmanageable health bill "is real, given the overall increases in prices in the health sector." The CNBC analysis of the Urban Institute's findings noted that the broader coverage conversation has shifted in 2026 — after years in which the main health policy debate centered on costs rather than coverage gaps, the expiration has reversed that dynamic.
Insurers also responded to the anticipated market disruption. Rate filings for 2026 reflect median premium increases of approximately 18%, the highest since 2018, driven in part by the expectation that healthier, younger enrollees would leave the market in greater numbers — worsening the risk pool for those who remained.
Who Faces the Greatest Risk?
People most likely to remain uninsured or face critical care access gaps in 2026 include:
- Adults earning between 100% and 400% of the federal poverty level who previously qualified for the largest subsidy enhancements
- Residents of states that did not expand Medicaid and have high baseline uninsured rates
- Young adults who were priced out by premium increases and are not eligible for employer coverage
- People with pre-existing conditions who need regular prescriptions or specialist visits and may be delaying care
- Residents of rural areas where provider networks are already limited
The KFF survey also found that an additional 17% of 2025 ACA enrollees are considered at risk of losing coverage — meaning the 9% already uninsured may not represent the full eventual impact.
What You Can Do Now
- Check your current coverage status. If you received a premium increase notice earlier this year and stopped paying, your coverage may have lapsed. Contact your insurer to confirm.
- Explore Medicaid eligibility. Depending on your state and income, you may qualify for Medicaid even if you did not previously. Use healthcare.gov or your state marketplace to check.
- Look for community health centers. Federally Qualified Health Centers (FQHCs) provide primary care on a sliding-fee scale regardless of insurance status.
- Ask your provider about patient assistance programs. Many pharmaceutical manufacturers offer free or reduced-cost prescriptions for uninsured patients. Generic alternatives are also often significantly cheaper.
- If you are between jobs, ask your former employer about COBRA continuation coverage and check whether you qualify for a Special Enrollment Period through the marketplace.
Cost and Access: What Patients Should Know
For people who are now uninsured, several practical options exist. Community health centers, which operate on a sliding-fee schedule based on income, provide primary care, preventive screenings, and some specialty referrals. Planned Parenthood affiliates and local health departments often provide reproductive and preventive care at reduced cost.
For prescription access, GoodRx and similar discount platforms can significantly reduce out-of-pocket drug costs even without insurance. Many brand-name manufacturers operate patient assistance programs that provide free or discounted medication to people who qualify based on income.
Telehealth providers have also expanded access for lower-cost virtual visits — a practical option for people who need a prescription refill or a consultation for a non-emergency concern.
What Happens Next
Congress is still debating whether to extend or permanently reintroduce enhanced premium tax credits. As of July 2026, no legislative extension has been enacted. Democrats in Congress have sought to include an extension in broader legislative packages, while negotiations remain ongoing.
The next major checkpoint will be the 2027 Open Enrollment period, expected to open in November 2026. Whether enhanced credits are restored before that window opens will significantly shape how many additional people lose or regain coverage going into the next plan year. MedicalDaily will continue tracking legislative developments and their impact on coverage access.
The Bottom Line
The largest single insurance coverage shock in years is no longer a projection; it is a documented reality. An estimated 4.8 million Americans are now uninsured as a direct result of the ACA enhanced subsidy expiration, with the hardest impacts concentrated in the South and among low- to moderate-income adults. If you or someone you know has stopped paying premiums or received no notices about coverage this year, it is worth checking your status now — before a health event forces the issue.
