Medicare Basics for Texans: Turning 65 Without Coverage

Medicare is the federal health coverage program that generally begins at 65, and earlier on certain disability grounds, and it is built in four parts: Part A hospital insurance, Part B medical insurance, Part C Medicare Advantage as a private alternative way of receiving Parts A and B, and Part D prescription drug coverage¹ (Medicare.gov, checked 30 July 2026). For a Texan reaching 65 after years without a card, the important thing is not the parts. It is the enrollment windows, because missing one can attach a surcharge to a premium that never comes off.

I sat with a man in a public library branch eleven days before his 65th birthday, and what he had brought was a folded pile of mail he had not been able to make sense of. He had run a small yard crew for most of his working life, had not seen a doctor since a work injury in his forties, and could not name a primary care physician when I asked. His question was not about premiums. It was whether turning 65 meant he could finally ask about the cough he had been living with. Eleven days is enough time to act and not enough time to be relaxed about it, and the whole appointment was about sequencing rather than about money.

That is the shape of this page. It is written for somebody arriving at 65 in a state with no adult Medicaid category, and it is honest about a real limitation: this site does not publish Medicare dollar figures, and there is a whole section below explaining exactly which numbers are missing and where to get them. Nothing here is an eligibility determination. Only Medicare and, for the Medicare Savings Programs, HHSC can decide your case.

What happens when a Texan turns 65 without coverage?

More often than in any other state, 65 is the first year of coverage rather than a change of coverage. Texas recorded 21.6% of adults aged 19 to 64 uninsured in 2024, the highest rate in the country for that age group, against a statewide all-ages rate of 16.7% and a national rate of 8.2%² (2024 data, checked 30 July 2026). Roughly one in six Texans, about 5.2 million people, had no coverage at all.

That produces a particular kind of 65th birthday. There is no established doctor, no medical record in one place, no history of prior authorizations or referrals, and often a list of things that have been postponed for a decade. The administrative task of enrolling is not the hard part. Finding somebody to be your doctor, and getting the postponed list in front of them in a sensible order, is.

It also produces a practical warning. People in this position frequently arrive at 65 believing Medicare will start automatically because they have heard that it does for some people. Whether it does depends on your circumstances, and that is precisely the sort of assumption that costs a window. Check with Medicare directly rather than with a neighbor.

What are the four parts of Medicare?

Part A is hospital insurance, Part B is medical insurance covering doctor and outpatient services, Part C is Medicare Advantage, a private plan alternative way of receiving your Part A and Part B benefits, and Part D is prescription drug coverage¹ (Medicare.gov, checked 30 July 2026). Medicare is administered federally by the Centers for Medicare and Medicaid Services, which is the single most useful thing to know about it on a Texas site: unlike almost everything else covered here, the rules do not change at the state line.

For someone coming out of long uninsurance, one distinction is worth holding on to. Part C is not a fifth benefit added on top. It is a different delivery route for the same Part A and Part B entitlement, run by a private insurer, usually with its own network and its own rules about referrals. That matters more to a person who has never navigated a network than to someone leaving a job plan, because network rules are the part that surprises people.

The population arriving at this door in Texas is large and poor. About 605,000 poor uninsured Texan adults aged 19 to 64 sit in the coverage gap, roughly half the national total of about 1.2 million across the ten non-expansion states³ (KFF estimates based on the 2024 American Community Survey, checked 30 July 2026). Age 64 is the last year in that count. For a good number of those people, Medicare is the first coverage of their adult life.

Why do the enrollment windows matter more than any other date?

Because enrolling late without other qualifying coverage can attach a surcharge to a premium, and that surcharge is generally permanent rather than a single penalty you pay off¹⁴ (Medicare.gov, checked 30 July 2026). Almost nothing else in the American coverage system works that way. A missed Marketplace open enrollment costs you a year. A missed Medicare window can cost you every month you are ever enrolled.

This site does not publish the length of any Medicare enrollment period, and you should not time yourself off a half remembered number from a friend or a mailer. Two specific confusions are worth clearing up:

• The Marketplace dates are not Medicare’s dates. Marketplace open enrollment starts 1 November, closes 15 January, and requires a 15 December sign-up for a 1 January start⁵ (checked 30 July 2026). Those dates have nothing to do with Medicare enrollment, and people conflate them constantly.
• Having some coverage is not the same as having qualifying coverage. Whether an employer plan, a retiree plan or another arrangement counts as qualifying coverage for delaying a Medicare part is a question with a specific answer, and it is Medicare’s answer to give.

The instruction that follows from this is simple and boring: put the question to Medicare.gov or to the Social Security Administration before your birthday, in writing, and note the date you asked and who answered.

Where are the Medicare Savings Programs decided?

Medicare Savings Programs help people with limited income and resources pay Medicare costs, and Medicare.gov states that they are administered through the state Medicaid agency, which in Texas is the Texas Health and Human Services Commission⁶⁷ (checked 30 July 2026). So the application goes to the state, not to Medicare, even though the benefit pays a federal program’s bills. People lose months to that one, calling the wrong office repeatedly and concluding they were not eligible.

One clarification that matters a great deal in Texas. The absence of Medicaid expansion here does not remove these programs. Medicare Savings Programs run through the state Medicaid agency in all fifty states, including the ten that have not adopted the ACA Medicaid expansion, of which Texas is one⁸ (checked 30 July 2026). What the expansion decision governs is whether the state has a general low income adult Medicaid category, and Texas does not: see Texas Medicaid eligibility. Somebody who has been told for twenty years that Texas Medicaid has nothing for them can quite reasonably assume that continues at 65, and on this specific point the assumption is wrong. Ask.

This site publishes no income limit and no asset limit for any Medicare Savings Program, and the reason is in the section below. HHSC and 2-1-1 Texas hold those numbers⁹. Applications to HHSC run through the same portal as other state programs: applying through YourTexasBenefits, and how HHSC counts money is worked through in what counts as income in Texas.

Can you hold Medicare and a Marketplace plan together?

No, they are not stacked, and HealthCare.gov publishes the rules for how the two interact¹⁰ (checked 30 July 2026). Reaching 65 with a Marketplace plan is a transition with its own sequence, not a renewal, and the cost of getting the order wrong lands on both sides at once.

For the years before 65, the Marketplace is where most Texans without a job plan end up, and the arithmetic is unforgiving at the bottom. Premium tax credits run from 100% to 400% of the federal poverty level¹¹ (checked 30 July 2026). The 2026 guideline for a household of one is $15,960 a year, so an adult of 62 or 63 earning less than that reaches neither the subsidy floor nor a Texas adult Medicaid category. HealthCare.gov’s own wording for people below 100% is that you probably will not qualify for savings on a Marketplace plan but may qualify for Medicaid, and in a non-expansion state there is nothing underneath. That is the Texas coverage gap in one paragraph, and it is why this coverage node dead ends for some adults until their 65th birthday. The mechanics of the subsidy itself are in how Marketplace subsidies work and the plans sold here are in Marketplace plans in Texas.

What do you do in the years before 65?

Use the routes that never ask whether you are covered, and start using them years before your birthday rather than in the month of it. The point is not only care in the meantime. It is arriving at 65 with a doctor who knows you and a record that exists.

• A federally funded community health center. Every health center in the federal Health Center Program must run a sliding fee discount schedule by household size and income: a full discount at or below 100% of the poverty guidelines unless the center elects a nominal charge, partial discounts in at least three pay classes between 100% and 200%, and no discount above 200%¹² (HRSA, page last reviewed November 2025, checked 30 July 2026). The operative line is that a center “must operate in a manner such that no patient shall be denied service due to an individual’s inability to pay”. The discount applies to the center’s own charges, so labs, imaging, referrals and prescriptions can be priced separately. See community health centers in Texas and how the sliding scale works.
• Your county’s indigent health care program. The statutory minimum standard “must incorporate a net income eligibility level equal to 21 percent of the federal poverty level”, counties may be more generous but not more restrictive, required services include payment for not more than three prescription drugs a month, and a county’s liability per eligible resident per state fiscal year is capped at 30 days of hospitalization or treatment in a skilled nursing facility, or $30,000, whichever occurs first¹³ (checked 30 July 2026). Full detail in county indigent health care program.
• Free and charitable clinics, which set their own rules and often reach incomes a health center’s 200% cut off excludes: free and charitable clinics.

Prescriptions are the item that most often breaks a budget in the years before Part D exists for you, and they have their own route map: prescriptions without insurance. The whole list is in getting care without insurance in Texas.

What this page does not publish about Medicare, and why

This site’s verified figure set contains no Medicare figures at all, so this page carries none. That is unusual enough on a coverage page that it deserves to be stated in full rather than glossed. Here is the precise list of what is deliberately absent:

• The Part A premium, and the circumstances in which there is none.
• The Part B premium, and any income related adjustment to it.
• Any Medicare deductible, copayment or coinsurance amount, in any part.
• The late enrollment penalty for any part: the amount, the percentage, how it is calculated, and how long it lasts.
• The length of any Medicare enrollment period, initial, general or special.
• The income limits and asset limits for every Medicare Savings Program.
• Income limits for the Texas Medicaid pathways tied to age, blindness or disability, which are assessed under different rules from the income tests used for the state’s family programs.

The reason governs every empty slot on this site, and it looks like a shortcoming when it is not. A figure that is close but stale does more harm here than a blank. Somebody who reads a stale Part B premium and decides it is unaffordable may let an enrollment window pass, and the surcharge for that is permanent. Somebody who reads a stale Medicare Savings Program income limit and rules themselves out never applies, and never learns they would have been approved. Neither of them writes in to correct us. So the number stays out until it has been read off Medicare.gov or a CMS source and stamped with a date.

It is worth being concrete about what filling one of those slots will look like, because the method is the part you can check. Medicare Savings Program eligibility is set as a percentage of the federal poverty level, and the guidelines are a figure this site does publish and re-checks every January: $15,960 a year for a household of one, $21,640 for two and $27,320 for three at the 2026 guidelines¹¹ (checked 30 July 2026). So when the program percentages have been read off a dated federal source, they will appear here measured against exactly those numbers, with the guideline year named. The scale is already present and dated. The percentage that multiplies it is what is missing, and it is the piece that decides cases, which is why it does not get estimated.

Where to get each of them today: Medicare.gov for premiums, deductibles, coinsurance, penalties and enrollment windows⁴; Medicare.gov’s Medicare Savings Programs page for what those programs are⁶; and HHSC for whether you qualify for one in Texas⁷. Neither this page nor any other website can decide it.

Which office answers which question

The single most useful skill in this subject is knowing who to call, because four different bodies each own a piece of it.

Question	Who answers
Am I eligible, when do I enroll, what does a part cost	Medicare, at Medicare.gov
Enrollment and the Part B decision at 65	Medicare and the Social Security Administration
Do I qualify for a Medicare Savings Program in Texas	HHSC
What happens to my Marketplace plan	HealthCare.gov, and the Marketplace call center on 1-800-318-2596
A local program, a clinic, or anything else in Texas	2-1-1 Texas, by dialing 2-1-1 or (877) 541-7905

Two of those are worth writing down before you need them. 2-1-1 Texas is reached by dialing 2-1-1 from anywhere in the state or (877) 541-7905, with live chat in English and Spanish, and it is operated by HHSC⁹ (checked 30 July 2026). The Marketplace call center is 1-800-318-2596, and HealthCare.gov’s own Medicare page is where the interaction between a Marketplace plan and Medicare is set out¹⁰ (checked 30 July 2026). Free help exists on the Marketplace side and is genuinely free: assisters certified by the Exchange are prohibited from charging applicants. For where Medicare sits alongside every other route into coverage in this state, start at health coverage in Texas, and for the state programs that run in parallel, Texas health programs.

Texas Care Map is an independent site with no affiliation to the State of Texas, HHSC, the Texas Department of Insurance or the Centers for Medicare and Medicaid Services, and it cannot enroll you in anything or decide anything about your case.
