How coverage works in Texas: Texas residents enroll through the federal marketplace at HealthCare.gov. Texas has not expanded Medicaid, which leaves a coverage gap for adults below 100% of the federal poverty level — the most important thing to understand before you shop. 15 carriers sell marketplace plans across 254 counties.

Understanding Health Coverage in Texas
The Texas Coverage Gap: The Most Important Thing to Understand
Texas has not expanded Medicaid, and that creates the single biggest coverage problem in the state. Texas Medicaid is limited mainly to children, pregnant women, people with disabilities, and elderly adults — non-disabled adults without dependent children generally cannot qualify regardless of how little they earn.
Meanwhile, marketplace premium tax credits start at 100% of the federal poverty level. That leaves the coverage gap: adults earning below 100% FPL who make too much for Texas Medicaid but too little for marketplace subsidies. It is a real and counterintuitive trap — earning more can qualify you for substantially cheaper coverage.
What to actually do if you're near that line: estimate your annual income carefully and honestly, including all self-employment and gig work. If your realistic projected income reaches 100% FPL (about $15,650 for a single adult), you become subsidy-eligible on the marketplace. Many people in the gap underestimate their own annual income and never learn they qualify. This is worth ten minutes with an advisor before assuming nothing is available.
Who Sells Coverage in Texas
For 2026, 15 carriers offer marketplace plans across Texas's 254 counties, with the typical county having 3 to choose from. The broadest availability comes from Blue Cross and Blue Shield of Texas, UnitedHealthcare, Ambetter from Superior HealthPlan. Full-price premiums for a 40-year-old start around $320 per month before subsidies, with the lowest-cost Silver plan near $540. Most enrollees pay far less once premium tax credits apply.
Carrier availability is decided county by county, not statewide — see the full Texas plan and premium comparison for the county-level breakdown, metal tiers, and deductibles.
Enrollment Timing in Texas
Open Enrollment for 2026 coverage runs November 1 through January 15 via HealthCare.gov. Outside that window you need a qualifying life event — losing job-based coverage, moving, marriage, divorce, a new baby, or certain income changes — which opens a 60-day Special Enrollment Period. Miss the 60 days and you generally wait for the next Open Enrollment, so act as soon as the event happens. Texas Medicaid, by contrast, accepts applications year-round.
Texas Health Insurance FAQ
How do I get health insurance in Texas?
Texas residents enroll through the federal marketplace at HealthCare.gov. Open Enrollment runs November 1 through January 15; outside that window you need a qualifying life event such as losing coverage, moving, marriage, or a new baby, which opens a 60-day Special Enrollment Period. Medicaid enrollment is year-round for those who qualify. A licensed independent advisor can compare every available plan for your county at no cost to you.
Does Texas have a Medicaid coverage gap?
Yes. Because Texas has not expanded Medicaid, adults earning below 100% of the federal poverty level can fall into the coverage gap — too much income for Texas Medicaid, too little for marketplace premium tax credits, which begin at 100% FPL. If your realistic annual income reaches roughly $15,650 as a single adult, you become subsidy-eligible, so estimating income accurately matters enormously here.
How many insurance companies offer marketplace plans in Texas?
For 2026, 15 carriers offer ACA marketplace plans in Texas across 254 counties. Availability is local: the typical county has about 3. Full-price premiums for a 40-year-old start near $320 per month before subsidies.
Do I qualify for a subsidy in Texas?
Premium tax credits are based on your household income relative to the federal poverty level and on the benchmark Silver plan in your rating area, so two Texas residents with the same income in different counties can receive different credits. If you are self-employed, the calculation uses your net income after business deductions — the single most common place people misestimate and overpay. Run the actual numbers before assuming you earn too much.
Can I be denied coverage in Texas for a pre-existing condition?
No. Every ACA marketplace plan sold in Texas must cover pre-existing conditions with no waiting period and no health underwriting, and must include the ten essential health benefits. Premiums vary only by age, ZIP code rating area, household size, and tobacco use.
What if I missed Open Enrollment in Texas?
Check three things in order: whether a qualifying life event opens a Special Enrollment Period for you, whether you qualify for Texas Medicaid (which enrolls year-round), and whether a medically underwritten private plan fits if you are healthy and have no other option. There is usually some door open — see our guide on what to do if you missed Open Enrollment.
