Health insurance policy doesn't sit still. The ACA has been amended, supplemented, challenged, and adjusted multiple times since its 2010 passage — and 2026 brings another wave of changes that affect Gulf Coast residents across Florida, Alabama, Mississippi, Louisiana, and Texas. Some changes are good news; others create uncertainty. Here's what you need to know.
The enhanced premium tax credit structure — which caps premium contributions at 8.5% of income regardless of income level above 400% FPL — was set to expire at the end of 2025. Legislative action extended these enhanced subsidies through 2026. For Gulf Coast residents currently enrolled with enhanced subsidy support, your current subsidy structure should remain in place for the 2026 plan year. The future beyond 2026 is uncertain — check with an agent for the most current legislative status.
ACA subsidy eligibility is based on the Federal Poverty Level (FPL), which is updated annually. The 2026 FPL for a single individual is approximately $15,650/year. Subsidy eligibility and Cost-Sharing Reduction thresholds shift accordingly each year. If you're near a subsidy threshold — 100%, 138%, 150%, 200%, or 250% FPL — a modest income change can significantly affect your subsidy and cost-sharing. Verify your projected 2026 income against updated FPL numbers.
The ACA's annual out-of-pocket maximum limits on in-network care are updated each plan year. In 2026, the individual maximum is $9,450 and the family maximum is $18,900. Plans cannot require you to pay more than these amounts for covered in-network services in a plan year — once you hit the maximum, the plan pays 100% of covered in-network costs for the rest of the year.
If you're enrolled in an HSA-compatible high-deductible health plan (HDHP), 2026 contribution limits are $4,300 for self-only coverage and $8,550 for family coverage. If you're 55 or older, you can contribute an additional $1,000 as a catch-up contribution. These limits increased from 2025, giving self-employed and small business owners on HDHPs additional tax-advantaged savings capacity.
The Inflation Reduction Act's drug pricing provisions continue phasing in for 2026. Medicare Part D enrollees saw the $2,000 annual Part D out-of-pocket cap take effect in 2025. For ACA marketplace plan enrollees, the drug pricing changes primarily affect Medicare beneficiaries rather than marketplace plan members — but watch for downstream formulary and price changes as manufacturers respond to Medicare negotiation outcomes.
Florida: Florida still has not expanded Medicaid as of 2026. The carrier market in major Florida Gulf Coast metros remains competitive — most markets have 4+ ACA carriers. Verify your current plan's network and premium for the 2026 year, as plans adjust annually.
Alabama: Alabama has not expanded Medicaid. Carrier competition remains limited — primarily BCBS Alabama and Ambetter/Centene. The limited competition continues to put upward pressure on premiums, but enhanced subsidies offset costs for most income-qualifying enrollees.
Mississippi: Mississippi's Medicaid situation remains complex in 2026 — the 2023 ballot initiative mandated expansion, but implementation has been slow. Check the Mississippi Division of Medicaid for current eligibility. The ACA marketplace has Ambetter, Molina, and BCBS Mississippi as primary options.
Louisiana: Louisiana's Medicaid expansion remains fully in force, covering adults up to 138% FPL. The marketplace has multiple carriers competing in major Louisiana markets. Louisiana Medicaid redeterminations (post-pandemic continuous enrollment unwind) have been ongoing — if you were on Medicaid and received a redetermination notice, verify your current eligibility status.
Texas: Texas continues to operate one of the nation's largest non-expansion state ACA markets. The major metro markets (Houston, San Antonio, Austin, Dallas) have robust carrier competition. Coastal and rural Texas counties have fewer options. The coverage gap for low-income adults without qualifying children remains unchanged.
