The Gulf Coast spans five states with vastly different Medicaid policies, creating a patchwork of coverage options depending entirely on which side of a state line you live on. A low-income hospitality worker in Mobile, Alabama may have full Medicaid coverage. An identical worker in Pensacola, Florida — 60 miles to the east — may have no affordable options at all. Understanding which tier of coverage applies to your household income is the foundation of getting insured on the Gulf Coast.
Gulf Coast residents generally fall into one of four income tiers, each with different coverage implications:
| Income Level | FL / TX / MS | AL / LA |
|---|---|---|
| Below 100% FPL (adult, no dependents) | Coverage gap — no Medicaid, no ACA subsidies | Medicaid eligible (expanded) |
| 100%–138% FPL | ACA marketplace with premium tax credit | Medicaid eligible (expanded) |
| 138%–250% FPL | ACA marketplace + CSR Silver plan recommended | ACA marketplace + CSR Silver plan |
| 250%–400% FPL | ACA marketplace with premium tax credit | ACA marketplace with premium tax credit |
| Above 400% FPL | ACA marketplace (may still have subsidies under enhanced rules) | ACA marketplace (may still have subsidies) |
Children and pregnant women have higher income thresholds and qualify for Medicaid or CHIP in all five states, even if their parents do not. See the CHIP and pregnancy sections below.
Alabama expanded Medicaid effective January 1, 2024, becoming one of the last Southern states to do so. Louisiana expanded in 2016. In both states, adults under 65 can qualify for Medicaid if their household income is at or below 138% of the Federal Poverty Level — approximately $20,783 for a single adult in 2026.
In Alabama, the expansion added an estimated 300,000 residents to coverage. Service workers, healthcare aides, restaurant employees, and hospitality workers earning below the threshold can enroll in Alabama Medicaid through the state agency. The federal government pays 90% of the costs for the expansion population, making it fiscally sustainable for the state.
Louisiana's 2016 expansion covered hundreds of thousands of residents across the state, including significant populations in New Orleans, Baton Rouge, Lake Charles, and the coastal parishes. Workers between offshore oil stints, seasonal hospitality workers, and low-income families in Acadiana and coastal Louisiana have all benefited from expanded eligibility.
To apply for Medicaid in Alabama: alabamamedicaid.alabama.gov. In Louisiana: medicaid.louisiana.gov. Both states also process applications through healthcare.gov.
In Florida, Texas, and Mississippi, Medicaid remains limited to specific categorical groups: children, pregnant women, very low-income parents of dependent children (at extremely restrictive income levels), people with disabilities, and the elderly in certain circumstances. A childless adult earning $12,000 per year is simply not covered in these states, regardless of health status or need.
Parents of children may qualify for Medicaid in these states, but the income limits are extremely restrictive — in Texas, for example, working parents must earn very little to qualify under the existing (non-expanded) rules. Check your state's Medicaid agency for current categorical income limits.
| State | CHIP Income Limit (Children under 19) | Monthly Premium |
|---|---|---|
| Florida | ~210% FPL | $0–$20/month depending on income |
| Alabama | ~141% FPL (Medicaid covers up higher thresholds) | $0 for most enrollees |
| Mississippi | ~209% FPL | $0–$10/month |
| Louisiana | ~212% FPL | $0 for most enrollees |
| Texas | ~200% FPL | $0–$50/month depending on income |
CHIP is separate from Medicaid in some states and combined in others. The application process is the same — healthcare.gov will screen your children for both programs simultaneously. Do not assume your children don't qualify without checking; CHIP income thresholds are generous in most Gulf Coast states.
All five Gulf Coast states offer Medicaid for pregnant women at income thresholds well above the standard adult Medicaid limits. This is true even in non-expansion states. If you are pregnant, you may qualify for Medicaid even in Florida, Texas, or Mississippi:
| State | Pregnancy Medicaid Income Limit (% FPL) |
|---|---|
| Florida | 196% FPL |
| Alabama | 215% FPL |
| Mississippi | 194% FPL |
| Louisiana | 263% FPL |
| Texas | 198% FPL |
Pregnancy Medicaid covers prenatal care, labor and delivery, and postpartum care for 60 days (or longer in some states). If you are pregnant and uninsured, apply immediately through your state Medicaid agency — coverage can be retroactive to the beginning of the month you apply.
For adults without dependent children in Florida, Texas, and Mississippi who earn below 100% FPL, there is no subsidized insurance pathway. The ACA was written assuming states would expand Medicaid — the subsidies start at 100% FPL because the drafters expected everyone below that threshold to be on Medicaid. When non-expansion states refused, the gap emerged.
If you are in the coverage gap, these are your realistic options:
All five Gulf Coast states use the federal marketplace at healthcare.gov for ACA plan enrollment. Premium tax credits are available at 100% FPL and above. Under the enhanced subsidy rules (originally from the American Rescue Plan), there is effectively no income ceiling on premium tax credits — even higher-income households may receive some subsidy if their benchmark plan would otherwise cost more than a set percentage of their income.
Cost-sharing reductions (CSRs) are available only to households enrolling in Silver plans with incomes between 100% and 250% FPL. CSRs reduce deductibles, copays, and out-of-pocket maximums — at 100–150% FPL, a Silver CSR plan can have a deductible as low as $300–$500, compared to $4,000+ on a typical Bronze plan. If you are in the 100–250% FPL range, always compare Silver plan options before defaulting to Bronze.
All Gulf Coast residents can apply for ACA marketplace coverage, Medicaid screening, and CHIP at healthcare.gov. The federal marketplace application screens automatically for Medicaid and CHIP eligibility before routing you to marketplace plans if you don't qualify for public coverage.
State Medicaid agencies also accept direct applications: alabamamedicaid.alabama.gov (AL), medicaid.la.gov (LA), medicaid.ms.gov (MS), hhs.texas.gov/medicaid (TX), and myflorida.com/accessflorida (FL). In Alabama and Louisiana, applying for Medicaid directly at the state agency may be faster if you clearly meet the expanded eligibility criteria.
Open enrollment for ACA marketplace plans runs November 1 through January 15 each year. Outside of open enrollment, a qualifying life event (job loss, birth, marriage, move) is required to enroll. Medicaid and CHIP have no enrollment window — you can apply at any time of year.
