What Are the Top 5 Medicare Supplement Plans in Texas?
If you're feeling overwhelmed by all the Medicare options out there, you're not alone - and you're in the right place.
Let’s start with the good news: when it comes to Medicare Supplement (Medigap) plans, most Texans choose from just a few top options.
Here are the Top 5 Medigap plans in Texas for 2025:
- Plan G – The most comprehensive coverage available to new enrollees
- Plan N – Lower premiums in exchange for small copays
- High-Deductible Plan G – Great for budget-conscious shoppers
- Plan K – A partial coverage option, often used by people under 65
- Plan F – Only available if you qualified for Medicare before January 1, 2020
These plans are popular for good reason - they offer simple, predictable, no-surprises coverage that lets you see the doctor without jumping through hoops.
At Policy Guide, we talk to Texans every day who are looking for freedom and peace of mind in their Medicare coverage.
Unlike Medicare Advantage, Medigap plans don’t lock you into a network or require prior authorizations for specialists.
You can see any doctor or hospital in Texas - or anywhere in the U.S. - as long as they accept Medicare.
No referrals. No red tape. Just coverage that works.
It’s no surprise over 780,000 Texans have already enrolled in Medigap plans. Nationally, these plans have a 90%+ satisfaction rate.
In this guide, we’ll break down each of these top 5 plans, explain who they’re best for, and help you find the one that fits your needs and budget.
What Are the Top 5 Medicare Supplement Plans?
We work with Medicare plans every day - and after helping hundreds of Texans, these are the plans we come back to again and again. They offer the best mix of coverage, value, and peace of mind.
Here are our favorite Medicare Supplement plans and why they stand out.
#1. Best for Full Coverage: Plan G
If you're looking for the most comprehensive Medicare Supplement plan available in Texas, Plan G is the go-to choice.
It's popular for a reason: it fills nearly every gap in Original Medicare - except for a small annual deductible (currently $257 in 2025 for Part B).
After that, you're covered.
Why Plan G Works for So Many Texans
Plan G is ideal if you:
- See the doctor often or manage chronic health conditions
- Want to avoid surprise bills and keep things predictable
- Prefer “set it and forget it” coverage that just works
This plan gives you peace of mind. Whether it’s specialist visits, lab work, or a hospital stay, you’ll know what to expect with your costs.
And you can go to any provider in Texas - or anywhere nationwide - that takes Medicare.
What Plan G Covers
Plan G covers:
- Medicare Part A coinsurance and hospital costs
- Skilled nursing facility care
- Blood (first 3 pints)
- Hospice care coinsurance
- Medicare Part B coinsurance and excess charges
- Foreign travel emergency coverage (up to plan limits)
The only thing you pay is the Part B deductible ($257 in 2025) - and after that, Medicare and your supplement pick up the rest.
How Much Does Plan G Cost in Texas?
Monthly premiums in Texas vary by ZIP code, age, gender, and whether you use tobacco. But here’s a general range to expect:
Average monthly premium: $160–$220/month (for a 65-year-old nonsmoker in Texas)
Some companies offer household discounts or other rate incentives, which can help lower your costs.
#2. Best Value Option: Plan N
If you’re looking for a smart middle ground - solid coverage with a lower monthly premium - then Medicare Supplement Plan N might be the best fit.
It offers nearly all the core benefits of Plan G, but with a few small trade-offs that can help keep your monthly cost down.
Plan N is a great choice if you:
- Are in good health and don’t see the doctor too often
- Want to save on premiums without giving up essential coverage
- Don’t mind small copays here and there
It’s especially popular among healthy retirees who value peace of mind but don’t want to overpay for coverage they may not use often.
What Plan N Covers
- Medicare Part A coinsurance and hospital costs
- Skilled nursing facility coinsurance
- Hospice care coinsurance
- Blood (first 3 pints)
- Medicare Part B coinsurance (with some exceptions)
- Foreign travel emergency coverage (up to plan limits)
What it doesn’t cover:
- Medicare Part B excess charges (these are rare and can be avoided by using Medicare-assigned providers.)
- Part B deductible (same as Plan G - $257 in 2025)
- Some small copays:
- Up to $20 for office visits
- Up to $50 for emergency room visits (waived if you're admitted)
- Up to $20 for office visits
In exchange for those small out-of-pocket costs, Plan N typically has a lower premium than Plan G - often by $20–$40/month.
Average monthly premium: $130–$190/month (for a 65-year-old nonsmoker in Texas)
Another bonus? Plan N tends to have smaller annual rate increases than Plan G, which can help keep your coverage affordable over time.
#3. Lowest Premium Option: High-Deductible Plan G
If keeping your monthly premiums as low as possible is your top priority - and you're okay with paying more out of pocket if and when you need care - then High-Deductible Plan G (HDG) could be a smart choice.
This plan offers the same benefits as regular Plan G, but only after you meet an annual deductible - $2,870 in 2025.
HDG is a great option if you:
- Rarely go to the doctor or use medical services
- Are generally healthy and want coverage for major unexpected costs
- Have an HSA or savings you can use to pay toward the deductible
- Want to be protected from big bills, but pay less every month
Just keep in mind - this plan isn't for everyone.
If you have a chronic condition or anticipate frequent doctor visits, you’ll likely end up paying more out of pocket in the long run.
That makes HDG best suited for those who want low premiums and are okay with front-loading their costs if care is needed.
What HDG Covers (After Deductible)
Once you hit the $2,870 deductible, your coverage works just like Plan G, including:
- Hospital stays
- Outpatient visits
- Skilled nursing care
- Blood, hospice care, Part B excess charges
- Foreign travel emergency
Until then, you’re responsible for 100% of Medicare-approved expenses (that Medigap would normally cover) - but not more than the deductible amount.
HDG Monthly Premiums in Texas
This is where HDG really shines - the premiums are the lowest of any Medigap plan.
Average monthly premium: $55–$95/month (for a 65-year-old nonsmoker in Texas)
For many Texans, that’s a savings of $1,000+ per year compared to standard Plan G - if you stay healthy.
#4. Best for Texans Under 65: Plan K
If you’re under 65 and on Medicare due to disability, you’ve probably noticed something frustrating - Medicare Supplement plans are a lot more expensive for you than they are for someone 65 or older.
In many Texas counties, Plan G or Plan N can cost $500–$1,000/month for someone under 65. That’s simply not affordable for most people.
That’s where Medicare Supplement Plan K comes in.
Why Plan K Is a Lifesaver for Some Texans Under 65
Plan K is often the only reasonably priced Medigap plan available for people under 65 on Medicare.
It doesn’t offer full coverage like Plan G or N, but it helps with the big expenses - and it’s a huge step up from relying on Original Medicare alone.
This plan is a fit if you:
- Are on disability Medicare and under age 65
- Need some help with costs but can’t afford full-coverage plans
- Want a safety net in place to limit worst-case out-of-pocket spending
What Plan K Covers
Plan K works differently than other Medigap plans. Instead of full coverage for certain benefits, it pays 50% of the cost for many services:
- Part B coinsurance (you pay the other 50%)
- Skilled nursing facility care
- First 3 pints of blood
- Hospice care coinsurance
It also fully covers:
- Medicare Part A coinsurance and hospital costs
- Once you reach the annual out-of-pocket limit, it covers 100% of covered services for the rest of the year: the out-of-pocket maximum for Plan K in 2025 is $7,220
Monthly Premiums for Plan K in Texas (Under 65)
If you’re under 65, Plan K is usually the most affordable Medigap plan available, with premiums that are less than half the cost of Plan G or N.
Estimated monthly premium: $230–$400/month (for someone under 65 on Medicare due to disability)
Availability varies by ZIP code, and fewer companies offer this plan - but it’s worth checking if you’re looking for meaningful coverage without a $1,000 price tag.
#5. Best if Eligible Before 2020: Plan F
If you qualified for Medicare before January 1, 2020, you’ve got a unique opportunity - you're still eligible for Plan F, the most comprehensive Medicare Supplement plan available.
While it’s no longer available to new Medicare beneficiaries, those who are grandfathered in can still apply (or switch) if the plan is offered in their area.
Why Plan F Is Still Worth Considering
Plan F is the only Medigap plan that covers every single out-of-pocket cost under Original Medicare - including the Part B deductible.
That means:
- No copays
- No deductibles
- No excess charges
- No out-of-pocket surprises
You pay your monthly premium and nothing else for Medicare-covered services.
It’s perfect for anyone who wants total predictability and zero bills at the doctor’s office, the hospital, or anywhere else.
Who Can Enroll in Plan F?
To buy Plan F, you must have been:
- Eligible for Medicare before January 1, 2020 (even if you didn’t sign up right away)
- In good enough health to pass underwriting, unless you're in a guaranteed issue period
If that applies to you, Plan F is still an option worth considering - especially if you're looking for peace of mind and don’t mind paying a bit more each month for it.
Plan F Monthly Premiums in Texas
Because Plan F offers full coverage, it comes at a higher cost. But for many, the tradeoff is worth it.
Estimated monthly premium: $240–$300/month (for a 65–70-year-old nonsmoker in Texas)
Premiums can vary depending on the carrier, ZIP code, and discounts available, so it’s always a good idea to compare quotes.
Choosing the Right Plan in Texas
There’s no one-size-fits-all Medicare Supplement plan - the best option for you depends on how you use your healthcare and what kind of budget you’re working with.
Here are a few simple questions to help you figure out which plan fits your lifestyle:
Do you travel frequently - within Texas or nationwide? All Medigap plans let you see any provider that accepts Medicare, but Plan G or N may be better if you want fuller coverage while on the go.
Do you visit doctors often or manage chronic conditions? If yes, Plan G offers predictability and full coverage after the small Part B deductible. If not, Plan N or HDG may give you better value.
Do you prefer predictable monthly costs or lower upfront premiums? Plan G is higher monthly but very little out of pocket. HDG is low monthly, but you’ll pay more if you need care.
Do you want zero billing surprises? Plan G and Plan F (if eligible) are your best bets. No copays, no excess charges, just straightforward coverage.

Can I Switch to Medigap Later?
Yes - in Texas, you can apply for a Medigap plan any time of year.
But outside of Open Enrollment or trial rights:
- Insurance companies can ask health questions
- They can deny your application or charge more based on your medical history
So while switching is possible, it’s not always guaranteed. If you’re thinking about switching, it’s best to talk with an agent who can walk you through underwriting and your eligibility.
Bottom Line
Choosing a Medicare Supplement plan in Texas isn’t about picking the “best” plan overall - it’s about finding the one that fits you.
Whether you want full coverage with no surprises, a lower monthly premium with manageable out-of-pocket costs, or something in between, there’s a Medigap plan that can match your needs.
For many Texans, the choice comes down to Plan G, Plan N, or High-Deductible G.
Each offers freedom to see any Medicare provider nationwide and protection from the red tape of Medicare Advantage.
And if you’re under 65 or eligible before 2020, there are still solid options available.
