Medicare Only Pays 80% — Here's What Covers the Rest

Original Medicare is a strong foundation, but it leaves you responsible for 20% of every Medicare-approved cost. For a hospital stay or a series of specialist visits, that 20% can add up quickly. Medicare Supplement plans — also called Medigap — are designed to fill that gap.

 

Medicare Supplement Plan G is the most popular choice for new enrollees in Texas. It covers 100% of Medicare-approved costs after the annual Part B deductible, which is approximately $257 in 2026. Once that deductible is met, clients enrolled in Plan G typically see zero additional bills for hospital stays, outpatient procedures, and specialist visits. Your monthly costs become predictable. The uncertainty goes away.

 

We've been helping Texas seniors navigate Medicare Supplement plans Texas since 1990, and the relief that comes with that kind of coverage clarity is consistent across every client we work with.

Every Plan G Policy Covers the Same Benefits — the Only Difference Is the Price

Medigap plans are standardized by federal law. Every Plan G policy sold in Texas covers the same benefits, regardless of which insurance company issues it. The carrier name on the card doesn't change what's covered — it only affects the monthly premium you pay.

 

Because we're an independent agency, we hold contracts with multiple top-rated carriers. We shop Medigap rates across those carriers on your behalf so you get identical coverage for less. There's no reason to pay more for the same plan.

 

  • Plan G covers all Medicare-approved costs after the Part B deductible
  • Plan N covers the same core benefits with a lower monthly premium and small copays for office and ER visits
  • Both plans work with any provider that accepts Medicare — no network restrictions apply
  • All standardized Medigap plans Texas residents purchase are guaranteed to carry the same benefits by law
  • We compare rates from multiple carriers at no cost to you

Plan G or Plan N — Which One Is Right for You?

Most new Medicare enrollees in Texas are choosing between two plans: Plan G and Plan N. Plan G covers 100% of Medicare-approved costs after the Part B deductible, with no copays and no surprises for covered services. Plan N carries a lower monthly premium in exchange for small copays — typically $20 for office visits and up to $50 for emergency room visits that don't result in an inpatient admission.

 

The right choice depends on how often you see doctors, your comfort with occasional out-of-pocket costs, and your monthly budget. In most cases, a single 30-minute consultation is all it takes to identify which plan makes more sense for your situation. We ask the right questions, run the numbers, and give you a clear recommendation — not a list of options to figure out on your own.

See Specialists Anywhere in the Country — No Referrals Required

One of the most meaningful advantages of a Medicare Supplement plan over Medicare Advantage is the absence of network restrictions. Any provider that accepts Medicare — across all 50 states — accepts your Medigap plan. That includes specialists at UT Southwestern, Baylor, and every major hospital system in the DFW area.

 

If you travel regularly, spend time in multiple states, or simply want the freedom to see whichever specialist your primary care doctor recommends without a prior authorization process, a Medicare Supplement plan is built for that. Coverage works the same whether you're in Dallas, Colorado, or visiting family across the country.

 

This is one of the clearest points of difference when comparing Medigap vs Medicare Advantage — and it matters most to the clients who value choice in their healthcare.

Enrollment Timing Matters More Than Most People Realize

The best time to enroll in a Medicare Supplement plan is during your Medigap Open Enrollment Period — the six-month window that begins the month you turn 65 and are enrolled in Medicare Part B. During this window, enrollment is guaranteed issue: no health questions, no medical underwriting, no risk of being declined or rated up for pre-existing conditions.

 

After that window closes, Texas generally requires health underwriting to enroll in or switch Medigap plans. That means your health history can affect your eligibility or your rate. Getting enrolled at the right time is one of the most concrete services we provide — we track your timeline, explain your options before the window opens, and walk you through the enrollment process step by step, including any paperwork through Medicare.gov or Social Security.

 

If you've already passed your initial enrollment window, we can still review your options and let you know what's available. Reach out and we'll take a look at where you stand.

Frequently Asked Questions About Medicare Supplement Plans in Texas

  • How much does Medicare Supplement Plan G cost in Texas?

    Medicare supplement Plan G cost in Texas varies by carrier, your age, your ZIP code, and whether you use tobacco. Rates for a 65-year-old non-tobacco user in the DFW area typically range from roughly $100 to $180 per month, depending on the carrier. Because Plan G benefits are identical across all carriers, comparing rates is straightforward — and we do that comparison for you at no charge.

  • What's the difference between Medigap and Medicare Advantage?

    Medicare Supplement (Medigap) plans work alongside Original Medicare and have no network restrictions — you can see any provider that accepts Medicare nationwide. Medicare Advantage plans replace Original Medicare and typically require you to use a network of doctors and obtain referrals for specialists. The right choice depends on your health needs, how often you travel, and your budget. We help clients think through both options clearly before making a decision.

  • Can I switch Medicare Supplement plans after I enroll?

    In Texas, switching Medigap plans outside of your Open Enrollment Period generally requires answering health questions, and carriers can decline coverage or charge higher rates based on your health history. There are limited special enrollment situations where guaranteed issue rights apply. If you're considering a switch, contact us first — we'll review your situation and let you know what's realistic before you make any changes.

  • Do Medicare Supplement plans cover prescription drugs?

    Medigap plans do not include prescription drug coverage. If you enroll in a Medicare Supplement plan, you'll need a separate Part D Prescription Drug Plan to cover medications. We help clients enroll in Part D alongside their Medigap plan so both pieces are in place from day one. What does "guaranteed issue" mean during Medigap Open Enrollment? Guaranteed issue means a carrier cannot decline your application, charge you a higher rate, or impose a waiting period based on your health history or pre-existing conditions. This protection applies during your six-month Medigap Open Enrollment Period. It's the most favorable window to enroll, and one of the reasons getting the timing right matters so much.
