2026 Medicare Supplement Cost Guide: What Seniors Need to Know

2026 Medicare Supplement Cost Guide: What Seniors Need to Know

Medicare Supplement insurance, also called Medigap, is private insurance that pays costs Original Medicare doesn’t cover — including Part A and Part B deductibles, coinsurance, and copayments. You pay a monthly premium to a private insurer alongside your Medicare Part B premium. Any doctor who accepts Medicare accepts your Medigap plan, with no network restrictions.

Staying informed about Medicare Supplement plans in 2026 is key to understanding the latest costs, knowing your coverage limits, and controlling out-of-pocket expenses. By learning about Medicare Supplement insurance options and how income levels impact premiums, you can make informed choices for your health and budget.

Here’s what seniors and their families need to know about the Medicare landscape in 2026, and how to choose the best Medigap plan for your circumstances.

Key Medicare Costs for 2026

Medicare costs can vary from one year to the next based on changes to Medicare as a whole and on your specific policy. Your Medicare costs for 2026 may include:

• Premiums: A premium is the amount you pay each month to maintain your Medicare coverage. For example, you might pay a Part B premium, a Part D premium, and a premium for your Medicare Supplement policy. The 2026 Medicare premium for Part B is $202.90 per month.
• Deductibles: A deductible is the amount that you pay out-of-pocket before your insurance policy covers you. The Medicare deductible for Part B is $283, which means you’ll have to pay for the first $283 in services you receive each year.
• Coinsurance: Coinsurance is the percentage of costs that you have to pay when you receive care. After meeting your deductible, Medicare typically pays 80%, which means your coinsurance is 20% for most services.

Here’s a quick guide to Medicare Part A and B costs for 2026:

While 2026 Medicare premiums are only slightly higher than last year, and most people don’t pay Part A premiums, the Medicare deductibles for Part A and B have increased. Coinsurance is still 20%, and there’s no out-of-pocket limit. These costs can add up without supplemental coverage, which is why many beneficiaries choose Medicare Supplement insurance to keep their Medicare Part A and B costs under control.

Understanding Medigap Plan Pricing

Medicare Supplement insurance, also known as Medigap, is a type of private health insurance plan that covers the “gaps” in Original Medicare, Parts A and B. Medigap pays some or all of your out-of-pocket expenses, such as your coinsurance and deductible. You’ll pay a separate premium for Medigap coverage, but you’ll have more predictable medical costs.

Medigap plans are standardized, which means that coverage options are consistent from one insurer to the next. But it’s still important to shop around for Medigap rates in 2026, because premiums can vary by age, location, and gender.

Some insurers also offer add-ons, such as dental and vision coverage, that aren’t part of Original Medicare.

The most popular Medigap plan types include:

• Plan F: This plan covers 100% of the Part A and B deductibles and coinsurance; the average monthly premium is $274.
• Plan G: This plan covers 100% of the Part A and B coinsurance, and 100% of the Part A deductible; the average monthly premium is $164.
• Plan N: This plan covers 100% of the Part A coinsurance and deductible, and the Part B coinsurance with a copay; the average monthly premium is $168.
• High-deductible F/G: These plans have lower premiums than the standard Plans F and G, but with a $2,950 deductible.

Plans K and L are the only plans with a Medigap out-of-pocket limit:

• Plan K: This plan pays 50% of the Part B coinsurance and Part A deductible, with an out-of-pocket limit of $8,000; average monthly premiums are $92.
• Plan L: This plan pays 75% of the Part B coinsurance and Part A deductible, with an out-of-pocket limit of $4,000; average monthly premiums are $192.

Here’s a breakdown of average Medigap rates by plan type:

Medicare Advantage Cost Considerations

Medicare Advantage, or Part C, is an alternative to Original Medicare that bundles coverage into an all-in-one policy. These plans are offered by private insurers, and more than 96% of plans provide supplemental benefits like hearing, vision, and dental coverage. Most plans also include prescription drug coverage, also known as Medicare Part D.

One benefit to enrolling in Medicare Advantage in 2026 is that you can get everything through a single policy, often with a lower premium than a Medigap plan. The average monthly premium is $14 in 2026, and some plans have $0 premiums.

However, you can expect more Medicare network restrictions than with Medigap plans. Most Medicare Advantage plans require you to obtain care from an in-network provider, and require prior authorization for certain procedures. With a Medigap plan, you can see almost any doctor, and most procedures don’t require prior authorization.

The potential for out-of-pocket costs is higher with a Medicare Advantage plan; the Part C maximum out-of-pocket, or MOOP, is capped at $9,250 in 2026, but Part D costs don’t count toward this limit.

Most Medigap plans cover the majority of your out-of-pocket costs; of those that don’t, they have a MOOP of $4,000 for Plan L and $8,000 for Plan K.

Here’s a quick overview of the differences between Medigap and Medicare Advantage:

Prescription Drug Coverage and Cost Caps

Medicare Part D prescription drug coverage can be purchased separately or is included with some Medicare Advantage plans. The maximum deductible for 2026 prescription drug coverage is $615, but some plans have a deductible as low as zero.

As of 2026, there’s a Medicare Part D cost cap of $2,100, which means that once you spend this amount, you won’t have to pay any more for the rest of the year.

There’s also a Medicare insulin cap that caps the cost of insulin at $35 for a one-month supply, with no deductible.

To estimate your actual medication costs, be sure to consider:

• Drug tiers: Each plan has its own formulary of medication with different “tiers” that determine their price. These range from low-cost generic drugs, or Tier 1, to specialty medications, or Tier 5. Make sure that the plan you choose has the medications you need at a suitable pricing tier.
• Coverage stages: Once you reach your deductible, which can be as low as $0 but no more than $615, you’ll enter the initial coverage stage, in which you pay 25% of the cost of your drugs.
• Cost cap: The catastrophic coverage stage applies after you reach the Medicare Part D cost cap, which is $2,100 for 2026 prescription drug coverage.

If you’re still struggling to afford the cost of drugs even with Part D coverage, you can spread out the cost with the Medicare Prescription Payment Plan. Instead of paying for them up-front at the pharmacy, you’ll get a bill from your drug plan with the balance, divided by the number of months remaining in the calendar year.

How Income Affects Medicare Premiums

The standard Part B premium is $202.90 per month, but higher-income beneficiaries may pay a surcharge called the income-related monthly adjustment amount, or IRMAA.

The 2026 Medicare income surcharge is based on your 2024 tax return, or 2023 if a more recent one isn’t available. This means that your past earnings, not your current earnings, determine your Medicare premium brackets.

You can estimate your modified adjusted gross income, or MAGI, which is similar to your adjusted gross income, to determine what your surcharge will be.

The 2026 IRMAA brackets are:

The Medicare income surcharge is recalculated on an annual basis, so your Parts B and D premiums could go up or down if your income changes. You can request a lower IRMAA from the Social Security Administration if you’ve had a life-changing event or you think the income on your tax return is incorrect.

Practical Steps to Manage 2026 Medicare Costs

With so many factors to consider, choosing the right plan can be complex. Follow these Medicare and Medigap shopping tips to help you plan ahead and manage costs:

• Medicare Open Enrollment runs from October 15 to December 7 2026, when you can make changes to your Medicare Advantage plan or drug plan for 2027. Medigap beneficiaries have more limitations on when they can switch.
• Review the Annual Notice of Change (ANOC) and Evidence of Coverage (EOC), which your plan should send you each year. This will let you know what changes in coverage or costs to expect in the next calendar year.
• Compare Part D prescription drug plans. Remember, it’s not just about finding the lowest premium, but about estimating your total drug costs over the course of the year, so you can find the right balance between premium and deductible.
• Get Medigap quotes from multiple insurance carriers, even if you’re happy with your plan. Some states have a “birthday rule” that allows beneficiaries to switch plans within a certain window, usually 60 days, of their birthday.
• If you’re enrolled in Medicare Advantage, look for any changes to your network and supplemental benefits coverage to make sure it’s still what you need.

If your current plan doesn’t cover everything you want it to, consider getting standalone vision and dental coverage to round out your Medicare benefits. Don’t forget to search for Medicare agents by location to get expert help and guidance on choosing the benefits that are right for you.
