Health Insurance in Dallas County, Texas

A County With World-Class Hospitals and Over Half a Million Uninsured Residents

Dallas County is home to more than 2.6 million people, anchor institutions like UT Southwestern Medical Center and Parkland Memorial Hospital, and major employers ranging from AT&T to Southwest Airlines. It is, by most measures, one of the most economically significant counties in the southern United States. And yet, roughly 24% of Dallas County residents under 65 — more than 528,000 people — carry no health insurance at all. That places Dallas County among the least-insured counties in the nation, ranked 7th worst in the country as of 2025 data.

The paradox is striking: a county with Parkland Memorial Hospital, the county's public safety-net institution with nearly 1,000 beds and one of the largest public hospital footprints in the United States, serving a population that overwhelmingly lacks the insurance coverage that makes planned, preventive care possible. Parkland exists precisely because so many Dallas County residents have nowhere else to turn — but emergency and charity care is not a substitute for coverage, and it does not protect families from financial ruin when serious illness strikes.

Understanding why so many residents remain uninsured — and what paths exist to change that — is the purpose of this guide.

What Many Dallas County Residents Get Wrong About Coverage

A common assumption in Dallas is that having access to world-class medical institutions means that getting insured, or getting care, is relatively straightforward. It is not. Several persistent misconceptions keep residents uninsured when coverage may actually be within reach — and trap others in gaps they did not know existed.

The Medicaid coverage gap. Texas did not expand Medicaid under the Affordable Care Act. That decision has consequences that land hardest on adults with very low incomes. If your household income falls below 100% of the Federal Poverty Level, you do not qualify for Texas Medicaid as an adult without dependent children, and you also cannot receive ACA marketplace subsidies — those subsidies begin at 100% FPL. This leaves a significant population in a coverage gap where no meaningful subsidized option exists through the standard channels. In Dallas County, this gap is particularly visible among uninsured Hispanic residents and foreign-born individuals, who are uninsured at rates of approximately 35% and 42% respectively.

The PPO myth. Many people shopping for individual health insurance in Texas expect to find PPO plans — the plan type that allows you to see out-of-network providers without a referral. PPO plans are not available on the Texas ACA marketplace. Plans sold through HealthCare.gov in Texas are HMOs and EPOs. This is not a detail; it fundamentally changes how you access specialists and which hospitals are covered. Before selecting any plan, verifying that your preferred providers and hospital systems — including UT Southwestern Medical Center, Baylor University Medical Center, Methodist Dallas Medical Center, Texas Health Presbyterian Hospital Dallas, and Children's Medical Center Dallas — are in-network is essential.

Assuming employer coverage is the default solution. Employer-sponsored insurance is often unavailable, unaffordable, or inadequate for workers at smaller businesses and in certain industries. The ACA marketplace may offer better options for some employees even when employer coverage exists, depending on whether that employer plan meets affordability standards under federal rules.

How to Enroll in Health Insurance in Texas: A Step-by-Step Guide

Texas is a federal marketplace state, meaning all individual and family marketplace plans are purchased through HealthCare.gov rather than a state-run exchange.

Step 1: Determine your eligibility. Your income relative to the Federal Poverty Level determines which programs and subsidies are available to you. Adults with income below 100% FPL fall into the coverage gap described above and should speak with a licensed producer about any available alternatives. Adults with income at or above 100% FPL may qualify for premium tax credits on the marketplace. Enhanced subsidies currently available mean that many enrollees qualify for meaningful financial assistance well above the 400% FPL threshold.

Step 2: Gather your documentation. You will need household income information, Social Security numbers for household members applying for coverage, and information about any employer coverage offers you may have received. Immigration status documentation may be required for non-citizen household members.

Step 3: Enroll during open enrollment. Open enrollment for the Texas marketplace runs from November 1 through January 15 each year. Plans purchased by December 15 take effect January 1; plans purchased between December 16 and January 15 take effect February 1. Missing the open enrollment window means waiting until the next period unless you qualify for a Special Enrollment Period.

Special Enrollment Periods. If you experience a qualifying life event — losing job-based coverage, getting married, having or adopting a child, moving to a new coverage area — you typically have 60 days from that event to enroll outside of open enrollment.

CHIP for children. Children in households that do not qualify for Medicaid but cannot afford marketplace plans may be eligible for the Children's Health Insurance Program. CHIP enrollment in Texas is year-round and income thresholds are higher than adult Medicaid limits. Families with uninsured children should explore CHIP eligibility regardless of their own coverage status.

Carriers and Plan Options in Dallas County

Dallas County is part of a major metropolitan area and benefits from one of the more competitive marketplace environments in Texas. Six confirmed carriers offer plans to Dallas County residents through HealthCare.gov:

• Blue Cross and Blue Shield of Texas — the state's largest insurer with broad provider networks and a long presence in the Texas individual market.
• Ambetter — a Centene subsidiary offering a range of metal-tier plans with competitive premiums, particularly at the Silver and Bronze levels where subsidy optimization is most impactful.
• Oscar Health — a technology-forward carrier with strong member tools, telehealth integration, and plan designs oriented toward younger and healthier enrollees.
• United Healthcare — one of the largest insurers in the country, with substantial network depth in the Dallas-Fort Worth metro area.
• Cigna — offers commercial marketplace plans with a focus on primary care access and preventive services.
• Molina Healthcare — specializes in serving lower-income enrollees and Medicaid populations, with marketplace plans positioned at competitive price points for subsidy-eligible residents.

All marketplace plans in Texas are HMOs or EPOs. An HMO (Health Maintenance Organization) requires you to select a primary care physician who coordinates referrals to specialists — all care must stay within the plan's network except in emergencies. An EPO (Exclusive Provider Organization) also restricts coverage to in-network providers but generally does not require referrals for specialist visits. Neither plan type covers out-of-network care except in emergencies. The practical implication: network adequacy matters enormously when selecting a plan in Dallas County. With multiple large hospital systems in the county, not every carrier contracts with every system — confirming that your preferred hospital or specialist participates in a plan's network before enrolling is a necessary step, not an optional one.

Plans are offered at four metal tiers — Bronze, Silver, Gold, and Platinum — reflecting the cost-sharing split between the plan and the enrollee. For most subsidy-eligible residents, Silver plans offer the most value because cost-sharing reductions (a second form of financial assistance) are only available at the Silver tier.

Common Mistakes to Avoid

Missing open enrollment without a backup plan. Open enrollment closes January 15. Residents who miss it without a qualifying life event must wait until the following November. This is one of the most common reasons uninsured Dallas County residents remain uninsured year after year.

Assuming PPO plans are available. As noted above, they are not. Enrolling in an HMO or EPO plan without verifying your providers are in-network can result in large unexpected bills when you receive care.

Not checking subsidy eligibility before declining coverage. Many residents assume marketplace coverage is unaffordable without checking whether they qualify for premium tax credits. Enhanced subsidies currently available mean that a large share of uninsured Dallas County residents who are above the coverage gap threshold may be able to obtain meaningful coverage at a significantly reduced cost.

Accepting employer coverage without comparing marketplace options. Employer plans that are deemed unaffordable under federal standards — meaning the employee's share of the premium for self-only coverage exceeds a set percentage of household income — may allow employees to access marketplace subsidies instead. This comparison is worth making, particularly for lower-wage workers offered coverage at small or mid-sized employers.

Overlooking CHIP for children while adults remain uninsured. Children and adults in the same household may qualify for different programs. Even if an adult parent is in the coverage gap, their children may qualify for CHIP. Leaving children uninsured when CHIP is available is an avoidable outcome.

Assuming the coverage gap is permanent. While Texas has not expanded Medicaid and the gap is a real barrier for many Dallas County residents, a licensed producer can help identify whether any transitional or alternative coverage options may apply. Federal policy also evolves — remaining informed about changes that may affect eligibility is worthwhile.
