Before you pick a Medicare path in Pasadena: how the two options actually work

Pasadena, Texas — When you become eligible for Medicare, you land at a fork in the road. One path keeps you on Original Medicare and lets you add a Medigap policy and a separate Part D drug plan. The other path moves your coverage over to a Medicare Advantage plan run by a private insurer. Both are legal, both are common, and both are available to people in Pasadena. But they are built very differently, and the choice you make shapes how you see doctors, how you pay bills, and how easy it is to switch later.

Key takeaways

  • Original Medicare with a Medigap policy and Original Medicare with a Medicare Advantage plan are two separate systems, not two versions of the same thing.
  • Medigap helps pay the out-of-pocket costs left by Original Medicare; Medicare Advantage replaces how Parts A and B are delivered.
  • In 2026, Part D has a $2,100 out-of-pocket cap and a maximum deductible of $615; in 2027, the cap is $2,400 and the maximum deductible is $700, no matter which path you choose for drug coverage.
  • The Annual Enrollment Period runs October 15 through December 7 each year, and Pasadena is in Harris County, where plan availability is set.

This guide walks through the structural difference between the two — not which is "better," because that depends on your health, your budget, and your doctors.

Path one: Original Medicare plus Medigap

Original Medicare is the federal program — Part A (hospital) and Part B (doctor and outpatient). You can see any provider in the country who accepts Medicare, and you don't need referrals. But Original Medicare alone leaves you with deductibles, coinsurance, and no yearly limit on what you might owe.

That's where Medigap (also called Medicare Supplement Insurance) comes in. Medigap policies are sold by private insurers and are standardized by letter — Plan G and Plan N are two common examples. A Plan G from one company covers the same gaps as a Plan G from another; the difference is price and customer service, not benefits.

If you go this route, you'll also want a stand-alone Part D plan for prescriptions, since Medigap does not include drug coverage.

Path two: Medicare Advantage

Medicare Advantage (Part C) is a bundled alternative. You're still enrolled in Medicare, but a private insurer manages your Part A and Part B benefits, usually adds Part D drug coverage, and often includes extras Original Medicare doesn't cover.

Advantage plans typically use networks — HMOs, PPOs, and similar structures — so which doctors and hospitals you can use, and how much you pay to see them, depends on the plan. Most set a yearly out-of-pocket maximum for medical costs, which Original Medicare by itself does not have.

Pasadena is in Harris County, where the Medicare Advantage lineup is set at the county level. That means the plans available to a Pasadena resident are the same ones available across Harris County.

How the money works differently

On the Medigap path, you pay a monthly premium for Part B, a monthly premium for your Medigap policy, and a monthly premium for your Part D drug plan. In exchange, most medical bills are predictable — the Medigap policy picks up much of what Original Medicare doesn't.

On the Medicare Advantage path, you still pay your Part B premium, and you may or may not pay an additional premium for the Advantage plan itself. Costs come in the form of copays and coinsurance as you use care, up to the plan's yearly out-of-pocket limit.

Neither path is automatically cheaper. A healthy person who rarely sees doctors and a person managing several chronic conditions can end up with very different totals under the same plan.

Drug coverage: the rules are the same

Whichever path you choose, Part D follows the same federal structure. In 2027, the maximum deductible any plan can charge is $700, and once your out-of-pocket spending on covered drugs reaches $2,400, you pay nothing more for the rest of the year. The old "donut hole" coverage gap was eliminated in 2025, so today there are three phases instead of four.

Medicare also offers the Medicare Prescription Payment Plan, an optional program that lets you spread your drug costs across the calendar year in monthly payments instead of paying large amounts at the pharmacy counter.

Switching between the paths later

This is the part many people don't hear about at 65. During your initial Medigap open enrollment window — the six months starting when you're 65 and enrolled in Part B — insurers must sell you a Medigap policy without asking health questions. Outside that window, in most states including Texas, Medigap insurers can use medical underwriting, which means they can charge more or decline coverage based on your health.

So while you can move from Medigap to Medicare Advantage fairly easily, moving back the other way later is not always guaranteed. It's worth thinking about at the start, not only at renewal time.

Key dates to remember

The Annual Enrollment Period runs October 15 through December 7. During this window, you can join, drop, or switch Medicare Advantage plans and Part D plans for the following year.

From January 1 through March 31, the Medicare Advantage Open Enrollment Period gives people already on an Advantage plan one chance to switch to a different Advantage plan or return to Original Medicare.

Higher-income beneficiaries should also know about IRMAA — an income-based surcharge that begins above $109,000 for single filers in 2026 and adds to Part B and Part D premiums.

Frequently asked questions

Can I have both a Medicare Advantage plan and a Medigap policy?
No. Medigap only works with Original Medicare. It is against federal rules for someone to sell you a Medigap policy if you're enrolled in a Medicare Advantage plan, because Medigap cannot pay the cost-sharing in an Advantage plan.
If I choose Medicare Advantage now, can I switch to Medigap later?
You can switch back to Original Medicare during the right enrollment window, but buying a Medigap policy later may involve medical underwriting in Texas. That means an insurer can consider your health when deciding whether to sell you a policy and at what price. Talk with your local SHIP counselor before assuming a future switch will be simple.
Does Original Medicare have a yearly out-of-pocket limit?
No. Original Medicare by itself has no cap on your annual medical costs, which is one reason many people pair it with a Medigap policy. Medicare Advantage plans, by contrast, are required to have a yearly out-of-pocket maximum on Part A and Part B services.
Where can I get help comparing the two paths for my situation?
Start at medicare.gov, where you can compare plans side by side using your ZIP code and your medications. You can also call 1-800-MEDICARE, 24 hours a day, or reach out to the Texas SHIP program (called HICAP in Texas) for free, unbiased counseling. ## Where to go next The choice between Original Medicare with Medigap and Medicare Advantage is one of the most important decisions you'll make as a new Medicare beneficiary. Take your time, write down your doctors and prescriptions, and use the official resources: medicare.gov, 1-800-MEDICARE, and your local State Health Insurance Assistance Program. These sources are free, and they don't sell plans.
