The Coverage Gap Leaves Millions Without Options
In the ten states that have not expanded Medicaid, an estimated 1.5 million low-income adults fall into a coverage gap — they earn too much to qualify for traditional Medicaid but too little to receive subsidies on the Affordable Care Act marketplace. These individuals, many of whom work in low-wage jobs without employer-sponsored insurance, are left with no affordable path to health coverage.
The coverage gap disproportionately affects people in Southern states, where non-expansion states are concentrated. In states like Texas, Mississippi, and Georgia, hundreds of thousands of working adults go without preventive care, chronic disease management, and mental health treatment because their state governments have declined to expand the program.
This is not an abstract policy debate. People in the coverage gap delay care until conditions become emergencies, resulting in worse health outcomes, higher costs to the health system, and preventable suffering that expansion would address.
The Economic Case for Expansion Is Overwhelming
Every state that has expanded Medicaid has seen significant economic benefits. Federal funding covers 90 percent of the cost of expansion enrollees, bringing billions of dollars into state economies that would otherwise be left on the table. Expansion states have seen job growth in the health care sector, reduced uncompensated care costs for hospitals, and lower rates of medical debt among their residents.
Studies from states like Kentucky, Montana, and Louisiana have documented that Medicaid expansion pays for itself by generating tax revenue from new health care jobs, reducing state spending on emergency services for the uninsured, and improving workforce productivity. The remaining holdout states are effectively turning away federal dollars that their residents have already paid for through taxes.
Rural hospitals in non-expansion states are closing at alarming rates, in part because they lack the Medicaid revenue that keeps similar facilities afloat in expansion states. Expanding Medicaid would stabilize these essential community institutions and protect access to care in underserved areas.
Health Outcomes Improve Dramatically with Expansion
The evidence that Medicaid expansion saves lives is no longer debatable. Research published in leading medical journals has found that expansion is associated with significant reductions in mortality, particularly from conditions like cardiovascular disease, diabetes, and cancer that benefit from early detection and consistent treatment.
Expansion states have also seen gains in mental health access, substance use treatment, and maternal health outcomes. People who gain Medicaid coverage are more likely to have a regular source of care, receive recommended screenings, and manage chronic conditions before they become life-threatening. These are not marginal improvements — they represent tens of thousands of lives saved and millions of people living healthier, more productive lives.
What Is Holding These States Back?
The decision not to expand Medicaid in the remaining holdout states is driven primarily by political opposition rather than fiscal or practical concerns. In several states, voters have approved expansion through ballot measures only to see implementation delayed or obstructed by state legislators. The federal government has offered enhanced financial incentives — most recently through the American Rescue Plan — that make expansion even more affordable for states.
Meanwhile, nearly 70 million Americans nationwide depend on Medicaid, and the program enjoys broad public support across party lines. Polls consistently show that majorities of voters in both expansion and non-expansion states support keeping Medicaid funded and accessible. The holdout states are out of step not only with the evidence but with the wishes of their own constituents.
Every day that expansion is delayed, people in the coverage gap go without the care they need. Expanding Medicaid in all 50 states would close the coverage gap entirely and bring the nation closer to the goal of universal access to affordable health care.
