Picking a Marketplace Plan in Texas: Deductible, Network, Formulary, Traps

A Marketplace plan’s real price is four numbers rather than one: the premium you pay every month, the deductible you pay before most coverage starts, the copays and coinsurance you pay when you use care, and the out-of-pocket maximum that caps the year. A plan that wins on the first number can lose badly on the other three, and the two checks that decide it, the provider network and the drug formulary, both have to be done before you enroll rather than after. Texas has more riding on that comparison than any other state: 16.7% of Texans were uninsured in 2024 against 8.2% nationally, which is roughly one in six people and about 5.2 million¹ (2024 data, checked 30 July 2026).

Thursday mornings I work the front desk of a free clinic in San Antonio, and plan comparison mistakes arrive there in January, about three weeks after they were made. The one I think about most was a woman who brought in the plan’s provider directory page, printed, with her doctor’s name highlighted, because she wanted somebody to explain why the office had just told her they were not in that network. They had left it in October. Her printout was accurate on the day she printed it and useless on the day she needed it. She had done more homework than almost anybody does, and it still did not hold, because she checked one source, once.

Nothing on this page is an eligibility determination or a price quote. Only the Marketplace can determine your premium tax credit and price a plan for your household. What this page can give you is the order to check things in, and the questions that make a directory or a formulary tell the truth. Every figure here carries the date it was checked.

What actually decides what a plan costs you?

Add the premium you will pay across twelve months to everything you expect to pay when you use care, and stop at the out-of-pocket maximum, because that is the ceiling. HealthCare.gov puts the same point in one sentence on its total costs page: the monthly premium is only part of what you spend on health care² (checked 30 July 2026).

The four numbers, in the order they hit you:

• Premium. Paid whether or not you see anybody. Missing one can end the plan.
• Deductible. What you pay for covered services before the plan begins paying its share. Some services, including preventive care, are covered before you meet it; the plan documents say which³.
• Copays and coinsurance. A flat amount, or a percentage of the cost, each time you use care after the deductible.
• Out-of-pocket maximum. The cap on what you pay in a plan year for covered in-network care. Premiums do not count toward it. Care outside the network usually does not either.

Two other numbers sit outside the plan and change the arithmetic. A premium tax credit lowers the monthly premium for a household between 100% and 400% of the federal poverty level⁴ (checked 30 July 2026), and that is worked through in how Marketplace subsidies work. A cost sharing reduction lowers the deductible, copays, coinsurance, and out-of-pocket maximum instead, and it attaches to Silver plans only, which is the single most expensive thing to get wrong in a comparison: cost sharing reductions. For where all of this sits in the wider picture, start at health coverage in Texas.

How do you check the network before you enroll?

Check three things by name, in writing and then by telephone: the doctor you use, the hospital you would actually be taken to, and every specialist you see regularly. HealthCare.gov’s plan comparison shows provider and drug information for each plan, and it is the right starting point rather than the finishing point⁵ (checked 30 July 2026).

The sequence that survives contact with reality:

1. Search the plan’s own directory by the person’s name and the office location, not by the practice group name, which can cover several networks.
2. Call the office and use the plan’s full name, including the metal level and the year. “Do you take Marketplace insurance” gets a yes that means nothing.
3. Ask about the hospital twice, once for the facility and once for the physicians who work inside it. A facility can be in network while the anesthesiologist, radiologist, or emergency physician billing you from inside it is not.
4. Write down the date and the name of whoever told you, because if it turns out to be wrong, that note is your evidence.
5. Repeat the hospital check in January, because networks reset with the plan year.

In Texas the hospital question is not theoretical. The UNC Sheps Center tracker records 25 rural hospital closures and conversions in Texas since 2005, and 22 since 2010, the highest of any state, with the next highest at 14⁶ (tracker updated 4 December 2025, checked 30 July 2026). Read it carefully: the tracker excludes conversions to Rural Emergency Hospitals, and a converted closure still provides some health care services, so it is not a count of towns left with nothing. What it does tell you is that in a lot of Texas counties there is one realistic hospital, and a plan whose network excludes it is a different product from the same plan bought in Dallas.

How do you check every drug against the formulary?

A plan covers a list of drugs, not drugs in general, and the list is arranged in tiers that decide what you pay. Prescription drugs are one of the benefit categories every Marketplace plan has to cover³ (checked 30 July 2026), which is a rule about the category and says nothing about your particular medication.

Take the bottles out of the cupboard and work down them one at a time:

• Find the plan’s formulary, the document listing covered drugs. It is separate from the summary of benefits.
• Look up each drug by name and dose, including the generic name, because a formulary can carry one strength and not another.
• Note the tier. Tier is what turns a covered drug into an affordable one, or does not.
• Check the conditions on the same entry. Prior authorization, step therapy, and quantity limits are separate restrictions that apply to drugs the plan does cover.
• Check the pharmacy network, including whether a maintenance medication has to go through mail order to be priced at the tier you were quoted.

Formularies and networks both reset with the plan year on 1 January, and open enrollment closes on 15 January⁷ (checked 30 July 2026), so the window in which you can respond to a change is short and it overlaps the change itself. If a drug you take is not on the list at all, price the alternatives before you decide, and read prescriptions without insurance for the routes that exist regardless of what a plan covers.

Why this page publishes no premium, deductible, or out-of-pocket maximum

Because not one of those figures has been read off a HealthCare.gov or CMS source and dated for Texas, and this site does not print a number it cannot stand behind. That is a deliberate hole rather than an omission. A plan cost quoted slightly low sends somebody to an application expecting a figure that is not there; quoted slightly high, it talks a household out of applying at all, and nobody ever comes back to tell us.

There is a second reason, specific to plan prices: there is no such thing as the Texas premium. Price varies by county, by age, by household size, by plan, and by year, so any single figure printed here would be wrong for almost everybody who read it.

What this site can publish, because it comes from a dated federal source, is the scale the whole system is measured against: the 2026 federal poverty guidelines for the 48 contiguous states run to $15,960 a year for a household of one and $27,320 for a household of three⁴ (checked 30 July 2026). Everything else in your comparison, the premium after any credit, the deductible, the out-of-pocket maximum, comes from one place only. The only accurate numbers are the ones on your own HealthCare.gov application, which prices your household rather than an average one, and you can see them before you commit to anything. The Marketplace call center is 1-800-318-2596 (checked 30 July 2026), and a free assister can sit with you while you read the results.

The traps, in the order they catch people

Most bad plan choices are not carelessness. They are one number being visible and three being hidden.

• The cheap premium with no hospital in it. The lowest monthly figure on the page is sometimes attached to the narrowest network. Check the hospital first, then the premium, because the order you check in decides what you notice.
• The drug that moves tier. A plan can keep covering a medication and reprice it at the start of the plan year. Re-check the formulary each January for the drugs you actually take, not once when you enroll.
• The directory that was right last month. Directories go stale between updates and contracts end mid-year, so the telephone confirmation, with a date and a name, is the check that holds.
• Assuming this year’s price is last year’s price. For plan year 2026 that assumption failed at scale. Premium payments net of tax credits rose 58% on average for people who signed up for 2026 coverage, which KFF elsewhere puts at about $780 more than the previous year, and national enrollment fell for the first time in seven years⁸ (checked 30 July 2026). In Texas, sign-ups rose by about 206,000 (a 5% increase) while effectuated enrollment fell by about 146,000 (a 4% decrease). Those two Texas numbers belong together: the first is people choosing a plan, the second is people still holding one after the premium came due.
• Buying something that is not a Marketplace plan at all. If it was sold by telephone outside open enrollment with no mention of a premium tax credit, check what it is before you cancel anything else: short term plans and health shares.
• Missing the window. After 15 January you need a qualifying life event to enroll: special enrollment periods.

What the law fixes about networks, and what it does not

Two protections sit underneath every network, and they are narrower than most people assume. The federal No Surprises Act, effective 2022, protects people in group and individual health plans from surprise bills for most emergency services, for non-emergency services from out-of-network providers at in-network facilities, and for out-of-network air ambulance services⁹ (checked 30 July 2026). Ground ambulance is not in the federal protected list, which in Texas is only half the answer, because state law reaches ground ambulance separately: the No Surprises Act, Texas balance billing law, and ambulance bills in Texas.

The second is EMTALA, enacted in 1986, which requires a Medicare-participating hospital offering emergency services to provide a medical screening examination and stabilizing treatment “regardless of an individual’s ability to pay”¹⁰ (CMS page last modified 10 March 2026, checked 30 July 2026). All three of its limits matter when you are weighing a narrow network: it is not free care and a bill follows, it reaches Medicare-participating hospitals that offer emergency services rather than clinics, urgent care, or physician offices, and it covers screening and stabilization rather than the ongoing treatment an emergency turns up. Go anyway if it is an emergency, and read EMTALA and the emergency room for how the bill afterward works.

Who helps you compare, and who is paid by whom

Free, impartial help exists, it is defined in federal regulation, and the difference from a commissioned salesperson is written into the rules rather than into anybody’s manner. A certified application counselor works for an organization designated by the Marketplace and, under 45 CFR 155.225, provides “fair, impartial, and accurate information”, passes Marketplace-approved certification exams, is recertified at least annually, agrees to act in the best interest of the applicants assisted, may not “impose any charge on applicants or enrollees”, and may not “receive any consideration directly or indirectly from any health insurance issuer” in connection with an enrollment¹¹ (checked 30 July 2026). A navigator program is grant funded, free to consumers, and required to be unbiased. Neither can give tax or legal advice, and both have to tell you so.

An agent or broker is licensed to sell Marketplace plans and is generally paid by the insurance companies whose plans they represent, and some may not sell plans from insurers they do not represent. That is a disclosure, not an accusation: it tells you which question to ask, which is “which companies do you represent”. Find local help at localhelp.healthcare.gov¹² (checked 30 July 2026). What is actually sold in this state is covered in Marketplace plans in Texas.

Where the decision is actually made

On your own application, inside the enrollment window, with the plan documents open. Open enrollment starts 1 November; enroll by 15 December for coverage starting 1 January; it closes 15 January, and a sign-up between 16 December and 15 January starts on 1 February⁷ (checked 30 July 2026). Medicaid and CHIP work differently and can be applied for at any time of year.

Before you enroll, put four things on one sheet of paper: the plan’s full name, the answer the hospital gave you and the date, the tier of every drug you take, and the out-of-pocket maximum. That sheet is the comparison. The monthly premium on the marketing page is one line of it.

If the arithmetic does not close, that is a real answer and it has its own map. Premium tax credits stop at 100% of the federal poverty level on the way down, and in Texas there is no Medicaid category underneath for most adults: the Texas coverage gap, and then getting care without insurance in Texas, which is the part of this subject nobody hands you. Texas Care Map is an independent publication. It has no affiliation with the State of Texas, the Texas Health and Human Services Commission, the Texas Department of Insurance, or the Centers for Medicare and Medicaid Services, and it cannot price a plan or decide a case for you.
