Gulf Coast Medicaid Income Guidelines by State — 2026

Updated May 2026

For Gulf Coast residents navigating health insurance, the single most important question is not which carrier offers the best plan — it's whether your state has expanded Medicaid under the Affordable Care Act. That one policy decision determines whether you have access to free or near-free comprehensive coverage or are left entirely without a subsidized option if your income falls below the poverty line.

Across the five Gulf Coast states — Florida, Texas, Alabama, Mississippi, and Louisiana — the expansion landscape is starkly divided. Two states (Alabama and Louisiana) have expanded, three (Florida, Texas, and Mississippi) have not. This guide covers the 2026 income thresholds, who qualifies, how to apply, and what to do if you're caught in the coverage gap in a non-expansion state.

5-State Medicaid Expansion Comparison

What the Coverage Gap Means — In Detail

The ACA was designed assuming all states would expand Medicaid. The original law structured the marketplace subsidies to begin at 100% of the Federal Poverty Level — the assumption being that anyone below 100% FPL would have Medicaid. When the Supreme Court made expansion optional and three Gulf Coast states declined, a structural gap opened up.

Florida Medicaid — Not Expanded

Florida's Medicaid program remains in its pre-ACA form. Adult Floridians without dependent minor children face an extremely narrow pathway — essentially no pathway — regardless of income. Florida does cover: children under 19 through CHIP (Florida KidCare) at incomes up to 200% FPL; pregnant women through the duration of pregnancy and a brief postpartum period; elderly adults (65+); and individuals with qualifying disabilities. Parents of dependent children may qualify but face strict income limits — typically well below the poverty line even in the parent category.

Florida's uninsured rate remains among the highest in the nation, directly driven by the non-expansion decision. Gulf Coast Florida counties — Pinellas, Hillsborough, Charlotte, Lee, Collier, Sarasota — have large populations of uninsured working adults who earn above the existing Medicaid limits but below 100% FPL, trapping them in the coverage gap.

Texas Medicaid — Not Expanded, Most Restrictive

Texas Medicaid is the most restrictive in the Gulf Coast region and one of the most restrictive in the country. The income limit for parents of dependent children in Texas is so low (around 18% of FPL for a parent household) that even very poor families with children often do not qualify. Adults without children face essentially zero Medicaid eligibility in Texas regardless of how low their income is.

Texas Gulf Coast counties — Harris (Houston), Galveston, Jefferson, Cameron, Nueces — have substantial populations of low-income workers in marine industries, petrochemical plants, agriculture, and service sectors who fall into this gap. Community Health Centers of the Gulf Coast and similar FQHCs provide the primary safety net for these residents.

Alabama Medicaid — Expanded January 2024

Alabama's Medicaid expansion took effect January 1, 2024, making it one of the most recent expansion states. Alabama now covers all adults ages 19–64 with income at or below 138% of the Federal Poverty Level. Enrollment is year-round — you can apply any time you qualify; there is no waiting period tied to open enrollment.

To apply for Alabama Medicaid: visit medicaid.alabama.gov or call 1-800-362-1504. You will need to verify identity, Alabama residency, and income. Alabama Gulf Coast counties — Mobile, Baldwin — now have residents who previously had no coverage option and can now receive Medicaid if their income qualifies.

Mississippi Medicaid — Not Expanded

Mississippi remains one of the holdout non-expansion states with no current legislation pending to change that status. Mississippi Medicaid (MississippiCAN) covers children through CHIP (up to 200% FPL), pregnant women during pregnancy and 60 days postpartum, elderly adults, and adults with qualifying disabilities. Working-age adults without dependent children — the largest group in the coverage gap — have no Medicaid pathway regardless of income.

Mississippi's Coverage for All Needs (CAN) program provides children's coverage and maternity services, but does not extend to working-age adults. The FQHC network — Delta Health Center, Pine Belt Medical Foundation, and others — is the primary resource for uninsured Mississippi Gulf Coast and Delta residents.

Louisiana Medicaid — Expanded 2016 (Healthy Louisiana)

Louisiana was among the earlier expansion states, expanding in 2016 under then-Governor John Bel Edwards. Healthy Louisiana covers all adults 19–64 at or below 138% FPL. Louisiana has built strong enrollment infrastructure over its 10 years of expansion operation — the application process is relatively streamlined and year-round enrollment is available.

To apply for Louisiana Medicaid: visit ldh.la.gov/medicaid or call 1-888-342-6207. Coastal Louisiana parishes — Orleans, Jefferson, St. Tammany, Terrebonne, Lafourche, St. Mary, Cameron — have significant populations who have used expansion Medicaid for the past decade, including many maritime, fishing, and oil and gas support workers.

What to Do If You're in the Coverage Gap

If you live in Florida, Texas, or Mississippi and your income falls below 100% FPL without a Medicaid pathway, your options include:

Federally Qualified Health Centers (FQHCs): Available in all five Gulf Coast states; provide primary care, dental, behavioral health, and pharmacy on a sliding-scale fee based on income. No insurance required. Find your nearest FQHC at findahealthcenter.hrsa.gov.

Hospital financial assistance programs: All nonprofit hospitals receiving federal funding are required to have charity care or financial assistance programs. If you face a large hospital bill while uninsured, request the financial assistance application immediately — many hospital systems will significantly reduce or zero out bills for patients below certain income thresholds.

Ryan White HIV/AIDS Program: For eligible individuals, Ryan White provides comprehensive health services regardless of insurance status.

Free and charitable clinics: Volunteer-staffed free clinics operate in many Gulf Coast communities and provide primary care and prescription assistance for uninsured low-income patients.

Contact a licensed agent: Sometimes income can be structured or documented in a way that opens marketplace subsidy eligibility. Self-employed workers, gig workers, and those with variable income sometimes misestimate their annual income — if your projected annual income reaches 100% FPL, marketplace plans with substantial subsidies become available. Call to review your situation.

Income Documentation for Medicaid and Marketplace Applications

Both Medicaid applications and ACA marketplace applications require income verification. The type of documentation varies by income source:

W-2 employees: Most recent pay stubs (last 2–4 weeks), plus prior year W-2s or tax return. For Medicaid applications, current pay stubs showing pay rate and hours are typically sufficient.

Self-employed workers: Most recent federal tax return (Schedule C net profit), plus current year-to-date profit/loss estimates. For the marketplace, you report projected annual income — which for contractors and fishermen with seasonal income requires honest estimation of the full calendar year.

Variable or seasonal income: Document all income sources — estimate conservatively if unsure. An accurate estimate prevents the need to repay subsidy if your actual income ends up higher. You can update your income estimate mid-year on Healthcare.gov if circumstances change.

For Medicaid: Social Security Administration letters (if receiving SSA income), award letters for any government benefits, and a copy of your prior year tax return if self-employed.

Moving Between Gulf Coast States — Coverage Implications

Moving between Gulf Coast states has direct health insurance consequences that are often underappreciated at the time of relocation. Moving from a non-expansion state (FL, TX, MS) to an expansion state (AL, LA) triggers both a marketplace Special Enrollment Period and potential immediate Medicaid eligibility. Moving from Louisiana or Alabama to Florida or Texas may mean losing Medicaid coverage entirely — you should enroll in a marketplace plan immediately upon establishing residency in a non-expansion state.

Moving is a qualifying life event (SEP) for the ACA marketplace. You have 60 days from establishing residency in a new state to enroll in a marketplace plan. Do not wait — there is no grace period beyond the 60-day SEP window.
