In the Kansas City area in 2026, a 65-year-old enrolling in a Medicare Supplement plan, also called Medigap, during their open enrollment window can usually expect Plan G to run about $120-$180 per month, Plan N about $90-$150 per month, and High-Deductible Plan G about $30-$60 per month.
Those ranges are not universal quotes. Your actual Medicare Supplement premium depends on your ZIP code, age, tobacco status, household discount, carrier, and the plan letter you choose. You still pay your Medicare Part B premium separately, and you usually need a Part D drug plan if you stay with Original Medicare.
That is the short answer. The better answer is to compare the total Medicare cost, not just the Medicare Supplement premium.

What Is a Medicare Supplement (Medigap) Plan?
Medicare Supplement insurance and Medigap mean the same thing. It works with Original Medicare, not in place of it.
Original Medicare pays first. The Medicare Supplement policy helps pay some or most of the deductibles, coinsurance, and copays that Original Medicare leaves behind. You can use any provider in the United States who accepts Medicare, which is one of the biggest reasons people choose a Supplement instead of Medicare Advantage.
Medicare Supplement plans do not include Part D prescription drug coverage. If you choose Original Medicare with a Supplement, you normally add a standalone Part D plan.

How Much Does Medicare Supplement Plan G Cost in 2026?
For a 65-year-old in the Kansas City metro, Plan G commonly falls around $120-$180 per month in 2026, depending on the carrier and applicant details.
Plan G is popular because it is simple. After you pay the Part B deductible, Plan G covers most remaining Medicare-approved out-of-pocket costs. That means no office visit copays, no hospital coinsurance surprises, and no network restrictions as long as the provider accepts Medicare.
Plan G usually fits people who want predictable costs, see doctors regularly, travel, or want the flexibility to use providers across Missouri, Kansas, and the rest of the country.
The premium is not the whole cost, though. With Plan G, your typical monthly Medicare stack looks like this:
- Part B premium
- Plan G premium
- Part D premium
- any IRMAA surcharge if your income is high enough

How Much Does Medicare Supplement Plan N Cost in 2026?
Plan N commonly runs about $90-$150 per month for a 65-year-old in the Kansas City area in 2026.
Plan N usually costs less than Plan G because it leaves you with more small costs. You may have office visit copays, emergency room copays, and potential Part B excess charges if a provider does not accept Medicare assignment.
For many healthy people turning 65, Plan N can be a strong option. The question is whether the premium savings are worth the extra friction and possible out-of-pocket costs.
I usually compare Plan G and Plan N side by side instead of assuming one is automatically better. A $30 monthly difference is $360 per year. If Plan N saves you more than you spend in copays and excess-charge risk, it can make sense. If you see specialists often, Plan G may be worth the higher premium.
I break that decision down here: Plan G vs. Plan N in Missouri.
How Much Does High-Deductible Plan G Cost in 2026?
High-Deductible Plan G is usually much cheaper per month. In the Kansas City area, a 65-year-old may see premiums around $30-$60 per month in 2026.
The tradeoff is the deductible. In 2026, High-Deductible Plan G requires you to pay Medicare-covered costs up to the high-deductible amount before the policy pays. Medicare lists the 2026 high-deductible amount for Plan G as $2,950.
This can work for someone who wants low monthly premiums and is comfortable taking more out-of-pocket risk. It is not the same experience as standard Plan G. You need enough cash flow or savings to handle the deductible if a bad health year arrives.
High-Deductible Plan G can look attractive on premium alone. It should still be compared against your health history, budget, and risk tolerance.
Why Do Medicare Supplement (Medigap) Prices Vary So Much?
Medicare says Medigap premiums vary by insurance company, plan, and where you live. The benefits are standardized by plan letter, which means Medicare Supplement Plan G from one carrier covers the same core benefits as Plan G from another carrier. The price can still be very different.
Medicare Supplement prices may vary because of:
- ZIP code
- age
- tobacco use
- household discounts
- carrier rate history
- the company’s pricing method
- whether you are applying during open enrollment or going through underwriting
This is why comparing only one carrier is not enough. Two companies can sell the same Plan G with the same standardized benefits and charge very different premiums.
Want Your Actual Medicare Supplement Rates?
The ranges above are a starting point, not a quote. If you want Medicare Supplement rates for your age, ZIP code, tobacco status, and household discount eligibility, reach out directly and I can compare the available carriers for you.
I work with people across Blue Springs, Lee’s Summit, Independence, Overland Park, and the full Kansas City metro. Call 816-291-3655 or schedule a free consultation. There is no cost to compare rates, and your premium is the same whether you enroll through an advisor or directly with the carrier.
How Do Medicare Supplement Companies Set Prices?
Medigap policies, or Medicare Supplement policies, can be priced in different ways.
Community-rated policies generally charge the same premium regardless of age, though premiums can still rise for inflation or other factors.
Issue-age-rated policies base the starting premium on your age when you buy the policy. Premiums can rise over time, but not because you get older.
Attained-age-rated policies are based on your current age, so the premium can increase as you get older.
That distinction matters because the lowest first-year premium is not always the best long-term value. When I compare Medicare Supplement plans for clients in Blue Springs, Lee’s Summit, Independence, and the full Kansas City metro, I look at the current premium and the carrier’s rate history.
Does a Medicare Supplement Cost More If You Wait?
It can.
Your Medigap Open Enrollment Period lasts 6 months. It starts the first month you are 65 or older and enrolled in Medicare Part B. During that period, you can buy any Medicare Supplement policy sold in your state without being denied because of health history.
After that window, your options may be more limited. In Missouri and Kansas, many people who apply later may have to answer health questions and go through medical underwriting. The carrier may deny the application or charge more depending on the situation.
That is why your first Medicare Supplement decision deserves real attention. You may not be able to move from a lower-premium plan to a richer plan later as easily as you expect.
Does IRMAA Affect Medicare Supplement Premiums?
No. IRMAA does not change your Medicare Supplement or Medigap premium.
IRMAA affects Medicare Part B and Part D costs for higher-income beneficiaries. If your income is high enough, you may pay more for Part B and may owe a Part D surcharge. Your Medigap carrier does not add IRMAA to the supplement premium.
The practical point is simple: when estimating your total Medicare cost, do not stop at the Medicare Supplement quote. Add Part B, Part D, and possible IRMAA too.
You can estimate that piece here: 2026 IRMAA calculator.
Medicare Supplement vs. Medicare Advantage Cost in 2026
Medicare Supplement, or Medigap, usually costs more each month than Medicare Advantage. That is the obvious tradeoff.
Many Medicare Advantage plans in the Kansas City area have $0 premiums. But they use networks, copays, prior authorization rules, and maximum out-of-pocket limits. In 2026, the Medicare Advantage in-network maximum out-of-pocket limit can be as high as $9,250.
Medicare Supplement works differently. You pay a monthly premium for more predictable costs and provider freedom. For someone who rarely uses care, Medicare Advantage may cost less in a normal year. For someone who wants nationwide access and fewer bill surprises, a Supplement may be worth the premium.
The right comparison is not premium versus premium. It is premium, risk, provider access, prescription needs, and how much uncertainty you are willing to carry.
What Should You Compare Before Choosing a Medicare Supplement Plan?
Before choosing a Medicare Supplement policy, compare:
- the plan letter
- the monthly premium
- household discount eligibility
- tobacco rating
- rate increase history
- carrier stability
- underwriting rules if you are outside open enrollment
- your separate Part D costs
The benefits are standardized, but the long-term cost is not.
For most people turning 65, I would rather see a careful comparison of three or four strong carriers than a quick decision based on the lowest first-year price. Cheap today can become expensive later if the rate history is poor.
How Medicare Supplement Costs Apply in Kansas City
In the Kansas City area, Medicare Supplement pricing can vary across ZIP codes and carriers. A Blue Springs resident may not see the exact same premium as someone in Overland Park, St. Joseph, or Raymore. Tobacco status, household discounts, and age can change the quote too.
The cross-state nature of the KC metro also matters. A Medicare Supplement’s provider freedom helps people who live in Missouri but see doctors in Kansas, or vice versa. With a Supplement, you are not trying to keep care inside a local plan network.
If you are comparing Medicare Supplement plans in Kansas City, the useful question is not just “What does Plan G cost?” It is “What will my total Medicare setup cost, and how much risk am I keeping?”
That is the number worth getting right.
Frequently Asked Questions
How much does a Medicare Supplement plan cost per month in 2026?
In the Kansas City area in 2026, a 65-year-old may see Plan G around $120-$180 per month, Plan N around $90-$150 per month, and High-Deductible Plan G around $30-$60 per month. Exact premiums depend on ZIP code, carrier, age, tobacco status, and discounts.
What is the cheapest Medicare Supplement plan in 2026?
High-Deductible Plan G is often one of the lowest-premium Medigap options, but it comes with more out-of-pocket exposure before the policy pays. Among standard plans, Plan N usually costs less than Plan G.
Why is one Plan G cheaper than another Plan G?
Medicare Supplement benefits are standardized by plan letter, but each insurance company sets its own premium. A cheaper Plan G does not mean weaker standardized benefits, but you still need to compare rate history, discounts, and carrier stability.
Does a Medicare Supplement include prescription drug coverage?
No. Modern Medicare Supplement, or Medigap, plans do not include Part D prescription drug coverage. If you choose Original Medicare with a Supplement, you usually need a separate Part D drug plan.
Can my Medicare Supplement premium increase every year?
Yes. Medicare Supplement premiums can increase over time because of age, inflation, claims experience, or carrier rate adjustments, depending on how the policy is priced. This is why the first-year premium should not be the only factor you compare.
