Medicaid Coverage Gap Checker 2025

Understanding the Medicaid Coverage Gap

The Medicaid coverage gap is one of the most overlooked and underreported health coverage crises in the United States. Millions of Americans — primarily low-income adults in states that have refused to expand Medicaid under the Affordable Care Act — find themselves in a no-man's-land where they earn too much for traditional Medicaid but too little to qualify for ACA Marketplace subsidies.

This tool is designed to help you quickly determine whether you fall in this gap — and, just as importantly, to understand what options may still be available to you.

How the Coverage Gap Came to Exist

When Congress passed the Affordable Care Act in 2010, the law included a sweeping expansion of Medicaid — the federal-state health insurance program for low-income Americans. The ACA required states to extend Medicaid eligibility to all adults earning up to 138% of the Federal Poverty Level (FPL), regardless of family status. In return, the federal government would cover 90% of the cost of newly eligible enrollees.

However, in 2012, the Supreme Court ruled in NFIB v. Sebelius that the Medicaid expansion was optional, not mandatory. States could choose whether to participate. Most states eventually accepted the expansion, but a significant number — predominantly in the South and Midwest — declined. As of 2025, roughly 10–12 states have still not fully expanded Medicaid.

The ACA's architects assumed all states would expand Medicaid, so they designed the law accordingly. ACA subsidies (premium tax credits) begin at 100% FPL — below that threshold, the law assumed you'd be covered by expanded Medicaid. In states that didn't expand, people earning below 100% FPL fall into a gap where neither program applies.

Who Falls in the Coverage Gap?

The coverage gap disproportionately affects certain groups:

• Working-age adults without dependent children — Traditional Medicaid in non-expansion states rarely covers childless adults at all, regardless of income.
• Gig workers and part-time employees — People with variable or seasonal income who earn less than $15,060/year as individuals.
• Workers in low-wage industries — Restaurant, retail, agricultural, and domestic workers are heavily represented in the coverage gap population.
• People of color — Due to structural inequities in low-wage employment, Black, Latino, and Indigenous Americans are disproportionately represented in the coverage gap.
• Rural residents — Rural areas in non-expansion states often have limited access to safety-net providers and face the additional burden of limited transportation.

According to the Kaiser Family Foundation, approximately 1.5–2 million Americans fell in the coverage gap as of 2024, down from a peak of over 4 million in earlier years as more states have gradually expanded Medicaid.

The 2025 Federal Poverty Level and What It Means

The Federal Poverty Level (FPL) is the benchmark used to determine eligibility for dozens of federal assistance programs, including Medicaid and ACA subsidies. For 2025, the FPL guidelines are:

In states that have expanded Medicaid, anyone earning below 138% FPL qualifies for Medicaid. In non-expansion states, Medicaid eligibility thresholds are dramatically lower — sometimes as low as 15–27% FPL for parents with children, and effectively zero for childless adults.

State-by-State Overview: Non-Expansion States in 2025

Each non-expansion state has slightly different Medicaid rules, but all share the same fundamental problem: residents earning below 100% FPL have no pathway to subsidized coverage.

• Texas — The largest coverage gap in the nation. Texas covers parents at roughly 15% FPL and does not cover childless adults through Medicaid at all.
• Florida — Covers parents up to about 26% FPL. Despite being the second-largest state by population, Florida has one of the most restrictive Medicaid programs in the country.
• Georgia — Implemented a partial "Pathways to Coverage" expansion in 2023 requiring work requirements, covering only a narrow slice of the gap population.
• Alabama and Mississippi — Among the poorest states in the nation, with Medicaid thresholds hovering around 18–27% FPL for limited populations.
• Tennessee — TennCare covers some populations but remains far below full expansion coverage.
• South Carolina, Wyoming, Kansas — Small to mid-sized coverage gap populations with limited state-level alternatives.

What Can You Do If You're in the Coverage Gap?

Being in the coverage gap doesn't mean you're completely without options. Here are the most important avenues to explore:

1. Federally Qualified Health Centers (FQHCs)

Community health centers receive federal funding to serve patients regardless of their ability to pay. They use a sliding-fee scale based on income, so even uninsured patients can access primary care, preventive services, dental, and behavioral health at little or no cost. Find your nearest FQHC at findahealthcenter.hrsa.gov.

2. Check for Special State Programs

Some non-expansion states have narrow programs for specific populations that may apply to you:

• Pregnant women (often covered up to 200%+ FPL even in non-expansion states)
• People with certain disabilities
• Foster care youth up to age 26
• Breast and cervical cancer treatment programs
• Emergency Medicaid for acute care situations

3. CHIP for Children

If you have children under 19, they may qualify for CHIP (Children's Health Insurance Program) regardless of whether you're in the coverage gap. CHIP covers children in families with incomes too high for Medicaid but too low for private insurance — typically up to 200% or even 300% FPL in most states.

4. Income Projection Strategy for Self-Employed

If you're self-employed with variable income, you may be able to project your annual income at 100% FPL or higher when applying for coverage. If you reasonably expect to earn at least 100% FPL over the course of the year, you may qualify for ACA subsidies. Learn more in our guide for self-employed health insurance strategies.

5. Short-Term Health Plans

Short-term health insurance plans are available in most states and don't require income-based eligibility. However, these plans have significant limitations: they don't cover pre-existing conditions, have limited benefits, and may deny claims after the fact. They are a last resort, not a solution — but for healthy individuals seeking catastrophic protection, they may be better than nothing.

6. Hospital Charity Care

Most hospitals that receive Medicare and Medicaid funding are required to have charity care programs. If you face a significant medical bill without insurance, ask about the hospital's financial assistance program. Many hospitals will reduce or eliminate bills for patients below a certain income threshold.

The Political Path to Closing the Gap

The most direct solution to the coverage gap is Medicaid expansion. Every state that has expanded Medicaid has seen dramatic reductions in uninsured rates, improvements in health outcomes, and — counterintuitively — improvements in state budget situations due to federal matching funds.

Advocacy is a real option. Organizations like the Health Justice Coalition, state-level policy groups, and voter initiatives have successfully pushed expansion in states like Oklahoma (2021), Missouri (2021), and South Dakota (2023). North Carolina completed its expansion in 2023 as well.

If you live in a non-expansion state, contacting your state legislators, supporting local advocacy organizations, and voting in state elections are meaningful ways to work toward closing the gap.
