Houston, Texas is a city of superlatives. It is the fourth-largest city in the United States, the energy capital of the world, and home to the Texas Medical Center — the largest medical complex on the planet, housing more than 60 institutions and 106,000 employees. It is also the most ethnically diverse major city in the country, with large communities speaking Spanish, Vietnamese, Mandarin, Cantonese, Hindi, and dozens of other languages. Yet despite all this medical infrastructure, Harris County has one of the highest uninsured rates of any large county in the nation — a direct consequence of Texas's decision not to expand Medicaid.
If you live or work in Houston and don't have employer-sponsored coverage, the ACA Marketplace is your primary path to affordable health insurance. This guide walks through the carriers available for 2026, how the Texas Medicaid gap affects your options, what coverage at Texas Medical Center looks like, and how much you can expect to pay at different income levels.
Under the Affordable Care Act, states were given the option to expand Medicaid to adults earning up to 138% of the federal poverty level (roughly $20,780 for a single adult in 2026). Texas is one of only ten states that has not expanded. This creates what policy experts call the "coverage gap" — adults without dependent children who earn less than 100% FPL (about $15,060/year) qualify for neither traditional Medicaid nor ACA marketplace subsidies. They simply fall through.
Harris County has an estimated 300,000–400,000 residents in this gap. Many are restaurant workers, domestic workers, day laborers, and gig economy participants — people who work hard but whose jobs don't offer benefits. If you fall in the gap, your best options are Harris Health System (the county's public health system, which provides sliding-scale care regardless of insurance status) and federally qualified health centers like Legacy Community Health, which operate on income-based fees. For preventive care and basic needs, these are real solutions. For hospitalizations and specialist care, the gap remains a serious vulnerability.
If you earn at or above 100% FPL, you qualify for ACA premium tax credits. A single adult earning $20,000/year may pay as little as $0–$50/month for a Silver plan after subsidies. The key is filing taxes and enrolling through healthcare.gov during open enrollment (November 1 – January 15) or during a Special Enrollment Period.
BCBS Texas remains the first choice for most Houston residents because of its network breadth. If your doctor or specialist is at Texas Medical Center or a major Houston hospital system, BCBS is almost certainly in-network. Ambetter is worth comparing if your priority is the lowest monthly premium and you're comfortable with an HMO model. Oscar Health is a good fit for younger, tech-comfortable enrollees who want integrated telehealth.
| Household Size / Income | % of FPL | Est. Monthly Premium (Silver) | Est. Annual Subsidy |
|---|---|---|---|
| Single adult, $25,000/yr | 166% | ~$50–$90/mo | ~$4,200–$4,800 |
| Single adult, $35,000/yr | 232% | ~$120–$160/mo | ~$3,200–$3,800 |
| Couple, $50,000/yr | 248% | ~$200–$260/mo (combined) | ~$5,500–$6,500 |
| Family of 3, $55,000/yr | 244% | ~$150–$220/mo (after subsidy) | ~$8,000–$9,500 |
| Single adult, $55,000/yr | 365% | ~$280–$340/mo | ~$1,500–$2,000 |

Harris County's diversity is extraordinary, and enrollment assistance is available in many languages. The ACA navigator program in Houston includes organizations fluent in Spanish, Vietnamese, Mandarin, Cantonese, Hindi, and Arabic. The Avenue CDC, United Way Greater Houston, and Lone Star Legal Aid all offer certified enrollment assistance at no cost.
The Southeast Houston Vietnamese community — concentrated in the Midtown and Bellaire areas — has access to Vietnamese-speaking navigators through several local nonprofits. Similarly, the large Houston Indian community (particularly in Sugar Land and Katy, which fall under Houston metro plans) has access to Hindi and Telugu-speaking assisters. If language is a barrier to enrollment, call our team at — we can connect you with the right resource.
The Texas Medical Center is not just Houston's largest employer — it is a medical destination that draws patients from across the Gulf Coast, Latin America, and the world. For Houston residents, proximity to TMC is a major asset, but only if your health plan includes its institutions in-network.
BCBS Texas plans generally include most Texas Medical Center institutions — MD Anderson Cancer Center, Houston Methodist, Texas Children's, Memorial Hermann TMC, and the UTHealth system — though specific hospitals vary by plan. Ambetter TX also covers many TMC institutions at the HMO level. Oscar Health's TMC network is narrower; check the plan's provider directory at healthcare.gov before enrolling if TMC access matters to you.
For cancer care, MD Anderson is a particular consideration. Some plans have specific MD Anderson network agreements; this is worth verifying before enrollment if you or a family member may need oncology services.
