12 States Refuse to Expand Medicaid. You're in the Coverage Gap If You Live in One.

The Supreme Court made Medicaid expansion optional in 2012. Fourteen years later, 12 states still haven't done it. In those states, someone earning $15,000 annually qualifies for nothing. Not Medicaid—they make too much. Not marketplace subsidies—they make too little. In expansion states, that same person gets free Medicaid. Your zip code determines your insurance status. This is the coverage gap. 2.9 million people live in it. Expansion would cost your state money. Non-expansion saves money and leaves millions uninsured. States made their choice.

Expansion vs. Non-Expansion: The Stark Difference

Expansion states cover adults to 138% of poverty. That's roughly $20,100 annually for an individual in 2026. Non-expansion states cap Medicaid below poverty or only cover parents and specific vulnerable populations. A childless adult in Texas earning $1 gets no Medicaid. Same person in California qualifies immediately. Income is identical. Geography determines coverage. This is intentional. States chose this.

Forty-one states plus D.C. expanded. Twelve states didn't: Texas, Florida, Georgia, Mississippi, South Carolina, Tennessee, Wyoming, Alabama, Oklahoma, Kansas, Maine, and Virginia. No—wait. Maine expanded. Virginia expanded. The number is smaller but the politics are fiercer. The states that haven't expanded are the ones saying no loudest.

The Expansion States: 41 Plus D.C.

Almost all states expanded. They cover working-age adults to 138% of poverty—roughly $20,100 for an individual in 2026. Northeast, Midwest, many Southern states, and Western states. Connecticut, Delaware, Massachusetts, Maine, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, Washington D.C. Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, Wisconsin. Arkansas, Louisiana, Maryland, North Carolina, West Virginia. Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington.

Expansion states offer simple eligibility: if your income is under 138% of poverty, you qualify. Many have added restrictions like work requirements. The baseline remains: adults under the threshold are covered.

Non-Expansion States: 12 That Refused Coverage

Twelve states rejected expansion. They maintain pre-ACA Medicaid limits. Non-expansion means covering extremely poor parents only—usually below 50% of poverty. Childless adults are excluded. Someone earning $15,000 in a non-expansion state doesn't qualify for Medicaid. The same person in an expansion state qualifies for free coverage. This is intentional policy. States chose not to expand.

*Florida maintains limited Medicaid coverage for extremely poor adults through legacy programs but does not cover childless adults under expansion.

The Coverage Gap: What It Means

The coverage gap exists specifically in non-expansion states. In these states, if you're a childless adult earning $0-$13,590/year (133% of FPL), you don't qualify for Medicaid. But if you earn $13,590-$20,385/year, you're too wealthy for Medicaid but your income is low enough that you don't qualify for ACA marketplace tax credits (which begin at 100% of FPL).

However, special enrollment periods exist. If you lose your job, experience a reduction in work hours, or lose employer coverage, you may qualify for an ACA marketplace special enrollment period and become eligible for subsidies even with lower income. This represents one pathway out of the coverage gap for those experiencing qualifying life events.

Impact on Specific Populations

The non-expansion states disproportionately affect:

• Working-age adults without children: These individuals have no pathway to Medicaid in non-expansion states regardless of income level.
• African Americans and Latinos: Non-expansion states have higher proportions of Black and Latino residents, meaning these communities bear a heavier burden of uninsurance.
• Rural residents: Rural areas in non-expansion states often lack access to safety-net providers, making the inability to access Medicaid particularly impactful.
• Individuals with chronic conditions: Those with diabetes, hypertension, or other chronic diseases fall through the cracks without preventive care access.

Income Limits by State: Detailed Reference

Expansion States Income Limits (2026)

Most expansion states maintain the 138% FPL threshold for adults 19-64. However, income limits for specific populations vary:

• Children: All states cover children up to at least 133% FPL; many expand coverage higher. Some states cover children up to 200-300% FPL.
• Pregnant women: Many expansion states offer coverage through 60 days postpartum. Some extend to 12 months.
• Seniors (65+): Most states maintain the federal requirement of 100% FPL for seniors.
• Individuals with disabilities: Coverage often extends to SSI recipients at 75% FPL, with many states offering higher limits.

Non-Expansion States Income Limits (2026)

Non-expansion states maintain much lower limits. For example:

• Texas: Adults 19-64 not eligible; parents covered only if earning less than 19% of FPL (approximately $250/month)
• Georgia: Parents covered to 50% of FPL; childless adults not covered
• Mississippi: Parents covered to 0% of FPL (no coverage); childless adults not covered
• South Carolina: Parents covered to 43% of FPL (approximately $600/month); childless adults not covered

Special Programs and Alternatives

Emergency Medicaid

All states, including non-expansion states, must provide emergency Medicaid to individuals regardless of immigration status or income when experiencing emergency medical conditions. This covers unpredictable emergency care only and doesn't provide preventive coverage.

Medicaid Waiver Programs

Some non-expansion states have implemented Medicaid waivers covering specific populations. For example, Kansas covers certain working individuals with disabilities, and North Carolina maintains legacy programs predating the ACA.

ACA Marketplace as Alternative

For those above Medicaid income thresholds, ACA marketplace plans with subsidies offer an alternative. However, subsidies are only available to those earning 100-400% of FPL. In non-expansion states, this creates a gap for those earning 0-100% of FPL.

Recent Policy Developments

State-Specific Expansion Efforts

Several non-expansion states have active campaigns to adopt expansion. In 2025-2026, increased political attention has focused on the coverage gap in states like Florida and Texas. Advocacy organizations have documented the impact of non-expansion on both individual health outcomes and state healthcare economics.

Financing Considerations

The ACA originally provided 100% federal funding for expansion populations (2014-2016), then phased to 90% federal/10% state funding (2020 onward). Expansion-resistant states cite budget concerns, though research indicates expansion typically increases state tax revenue and reduces uncompensated care costs in hospitals and emergency departments.

Determining Your Eligibility

Step 1: Find Your State's Income Limit

Visit your state's Medicaid website (typically Medicaid.gov or state-specific domain) and locate income limits for your category (adult, parent, pregnant, disabled, child).

Step 2: Calculate Your Household Income

Medicaid typically uses modified adjusted gross income (MAGI), which is generally your federal income tax filing income. Some deductions apply. Contact your state for guidance on specific deductions.

Step 3: Apply or Check Eligibility

Most states allow online applications through Healthcare.gov or state-specific portals. The application system will compare your income to your state's limits and provide an eligibility determination.

Step 4: Appeal If Denied

If denied and you believe your income qualifies, request a fair hearing through your state. Administrative law judges have overturned many denials based on income miscalculation or policy misapplication.
