What Does Medicare Plan K Cover?

What Does Medicare Plan K Cover? Understanding Specific Coverage Details of Plan K

Medicare Plan K pays about half of your Medicare costs, including your hospital deductible and 20% of your doctor bills. In return, you pay less each month. It also has a yearly spending cap. In 2026, that cap is $8,000. For 2027, it goes up to $8,360. Once you hit the cap, Plan K pays 100% of your covered costs for the rest of the year.

I know Medicare can feel like a big bowl of alphabet soup. There are Parts A, B, C, and D. Then there are Medigap plans with letters like G, N, and K. When I first started learning about this stuff, my head was spinning. So in this article, I’m going to break down Medicare Plan K in plain, simple words.

By the end, you’ll know what Plan K covers, what it doesn’t cover, how much it might cost, and whether it could be a good fit for you.

What Is Medicare Plan K?

First, let me clear up one thing. Medicare Plan K is not the same as Medicare Part K. There is no Part K. Plan K is a Medicare Supplement plan. People also call these Medigap plans.

Here’s how it works. Original Medicare (Part A and Part B) pays for a lot of your health care. But it doesn’t pay for everything. You still have deductibles, copays, and coinsurance. Those are the “gaps.” A Medigap plan helps fill those gaps.

Private insurance companies sell Medigap plans. But the government sets the rules for what each plan covers. That means Plan K from one company covers the same things as Plan K from another company. The only big difference is the price.

There are 10 standard Medigap plans. Each one has a letter: A, B, C, D, F, G, K, L, M, and N. Plan K is one of only two plans with a yearly out-of-pocket limit. The other one is Plan L.

One quick note: If you live in Massachusetts, Minnesota, or Wisconsin, your state uses its own Medigap rules. You won’t find Plan K there in the same form.

What Does Medicare Plan K Cover? The Quick Answer

If you’re short on time, here’s the list I wish someone had handed me. This is what Plan K pays for:

And here’s the big bonus: once you reach the yearly out-of-pocket limit ($8,000 in 2026) and pay your Part B deductible, Plan K pays 100% of covered costs for the rest of the year.

So here’s the simple way I think about it. Plan K is like splitting the bill with a friend. You each pay half. But if the bill gets huge, your friend steps in and pays it all.

A Closer Look at Each Plan K Benefit

Now let me walk you through each benefit, one at a time. I’ll keep it simple.

1. Hospital Coinsurance and 365 Extra Days (100%)

This is the one part of Plan K that pays in full right away. If you stay in the hospital for a long time, Medicare Part A starts charging you a daily coinsurance after day 60. That cost goes up even more after day 90.

Plan K pays all of that daily coinsurance. It also adds 365 more hospital days after you use up your Medicare days. Long hospital stays don’t happen often. But when they do, the bills can be scary. I like that Plan K covers this.

2. The Part A Deductible (50%)

When you go into the hospital, you have to pay the Part A deductible first. In 2026, that’s $1,736. Plan K pays half, so you pay $868.

Here’s a tricky part. The Part A deductible isn’t annual. It’s once per benefit period. A benefit period starts when you go into the hospital. It ends when you’ve been out of the hospital or nursing facility for 60 consecutive days. So if you go in twice in one year, you could owe this deductible twice.

3. Part B Coinsurance (50%)

Part B covers doctor visits, outpatient care, lab tests, and medical equipment. After you pay the Part B deductible, Medicare usually pays 80%. You pay the other 20%.

With Plan K, you split that 20% in half. So you pay about 10%, and Plan K pays about 10%.

Let’s say you have a $500 outpatient procedure. Your 20% share is $100. Plan K pays $50. You pay $50.

4. Preventive Care (100%)

Good news here. Medicare already pays for most preventive care in full. That includes your yearly wellness visit, flu shots, and many cancer screenings. You usually pay $0 for these with or without Plan K.

5. Blood (50%)

If you need a blood transfusion, Medicare doesn’t pay for the first 3 pints. Plan K pays half of the cost for those 3 pints.

6. Hospice Care (50%)

Hospice care is comfort care for people at the end of life. Medicare covers most of it. But you may have small copays, like for pain medicine or short respite stays. Plan K pays half of those costs.

7. Skilled Nursing Facility Care (50%)

Sometimes after a hospital stay, you need extra care in a skilled nursing facility. Medicare pays the full cost for the first 20 days. From day 21 to day 100, you owe a daily coinsurance. Plan K pays half of that daily amount.

8. The Yearly Out-of-Pocket Limit

This is what makes Plan K special. Most Medigap plans have no yearly cap. Plan K does.

• 2026 limit: $8,000
• 2027 limit: $8,360

Once you pay that much in covered costs, and you’ve paid your Part B deductible, Plan K pays 100% for the rest of the calendar year. Then the count starts over on January 1.

What Does Medicare Plan K NOT Cover?

Knowing what a plan doesn’t cover is just as important as knowing what it does. I’ve seen people get surprised by bills because they skipped this part. So here’s the list.

Plan K does not pay for:

1. The Part B deductible. You pay the full $283 yourself in 2026.
2. Part B excess charges. Some doctors don’t accept Medicare’s set price. They can charge you up to 15% more. Plan K won’t pay that extra amount. (Tip: Ask your doctor if they “accept assignment.” If they do, you won’t get excess charges.)
3. Emergency care outside the U.S. If you travel a lot, this matters. Plans like G and N cover some foreign travel emergencies. Plan K doesn’t.
4. Prescription drugs. No Medigap plan sold today covers drugs you pick up at the pharmacy. You’ll want a separate Part D drug plan.
5. Dental, vision, and hearing. Routine teeth cleanings, eye exams, glasses, and hearing aids are not covered.
6. Long-term care. This means help with daily tasks, like bathing or dressing, in a nursing home or at home. Medicare and Medigap don’t pay for this kind of care.
7. Private-duty nursing. If you want a nurse just for you, you’ll pay for that yourself.

There’s one more thing to know. Only costs that Medicare covers count toward your $8,000 limit. So money you spend on drugs, dental work, or eyeglasses won’t count toward the cap. The Part B excess charges don’t count either.

How the Plan K Out-of-Pocket Limit Works (With Real Examples)

Numbers make more sense when you see them in action. So let me show you three made-up people with three very different years. I’ll use 2026 costs.

Example 1: Linda Has a Quiet Year

Linda sees her doctor a few times and gets some lab work. Her Medicare-approved bills come to $1,000.

• She pays the Part B deductible: $283
• That leaves $717. Her 20% share is $143.40.
• Plan K pays half of that. Linda pays: $71.70
• Linda’s total for the year: $354.70 (plus her monthly premiums)

In a light year like this, Plan K works really well. Linda saves money because her premium is low.

Example 2: James Goes to the Hospital

James has a short hospital stay. Later, he has $20,000 in outpatient care.

• Half of the Part A deductible: $868
• The Part B deductible: $283
• His 20% share of the outpatient bills is $4,000. Plan K pays half. James pays: $2,000
• James’s total for the year: $3,151

That’s a real chunk of money. But it’s a lot less than he’d pay with Original Medicare alone. With no Medigap plan, he’d owe more than $6,000.

Example 3: Rosa Has a Very Hard Year

Rosa gets sick and needs a long string of treatments. Her half of the costs would total $11,000.

But Plan K has a cap. Once Rosa’s covered costs hit $8,000, Plan K pays 100% for the rest of the year. So Rosa pays $8,000, not $11,000. That cap saves her $3,000.

What I Want You to Take Away

Plan K protects you from the worst-case year. But that protection kicks in late. In a bad year, $8,000 is still a lot of money. Before you pick Plan K, ask yourself: “Could I pay $8,000 if I had to?” If the answer is no, a plan with more upfront coverage might help you sleep better.

Plan K vs. Plan G, Plan N, and Plan L

When people ask me about Plan K, they almost always ask how it compares to other plans. Here’s a side-by-side look at four popular choices.

Here’s how I’d sum up each one:

• Plan G covers almost everything except the Part B deductible. It costs more each month, but your bills stay small and predictable.
• Plan N is similar to Plan G, but you pay small copays for some office and emergency room visits. It usually costs a bit less than Plan G.
• Plan L is Plan K’s big sibling. It pays 75% instead of 50%. Its cap is lower too: $4,000 in 2026 and $4,180 in 2027.
• Plan K has the lowest premium of these four. But you share more of the costs until you hit the cap.

Why don’t Plans G and N have a cap? Because they pay so much up front that most people never get close to big bills. Plans K and L pay less up front, so the cap acts like a safety net.

How Much Does Medicare Plan K Cost?

I can’t give you one exact price, and here’s why. Plan K prices change based on:

1. Where you live; prices can vary widely from one zip code to the next.
2. Your age. Many plans cost more as you get older.
3. Your gender. Some companies charge women and men different rates.
4. Tobacco use. Smokers often pay more.
5. How the company sets its prices. Some lock your price to the age you were when you bought the plan. Others raise it as you age.

Remember, Plan K covers the same things no matter which company sells it. So it makes sense to compare prices from a few companies. A cheaper Plan K gives you the same benefits as a pricey one.

Also, don’t forget: you still pay your Part B premium to Medicare. In 2026, the standard Part B premium is $202.90 a month. Your Plan K premium is on top of that.

Who Is Plan K a Good Fit For?

From what I’ve seen, Plan K tends to work well for people who:

• Are fairly healthy and don’t see the doctor much
• Want a low monthly bill
• Have some savings to cover costs if they get sick
• Want a cap on their yearly spending, which Original Medicare alone doesn’t have
• Don’t travel outside the U.S. very often

Plan K might not be a good fit if you:

• Have a long-term health problem and see doctors often
• Want to know exactly what you’ll pay each month
• Would struggle to pay a few thousand dollars in a bad year
• Travel abroad a lot
• See doctors who don’t accept Medicare’s set price

Plan K Pros and Cons

Here’s a quick look at the good and the not-so-good.

Pros:

1. Lower monthly premium than Plans G and N
2. A yearly cap on your covered costs
3. 100% coverage for hospital coinsurance and 365 extra hospital days
4. You can see any doctor in the U.S. who takes Medicare. No networks.
5. No referrals needed to see a specialist

Cons:

1. You pay half of most costs until you hit the cap
2. The cap is high ($8,000 in 2026)
3. No help with the Part B deductible or excess charges
4. No foreign travel coverage
5. Your yearly costs can jump around a lot

Medicare Plan K FAQs

Here are the questions I hear most often about Plan K.

Does Medicare Plan K cover prescription drugs?

No. Plan K does not cover drugs you get at the pharmacy. For that, you need a separate Medicare Part D plan. Good news: Part D has its own yearly cap. In 2026, it’s $2,100.

Does Plan K cover dental, vision, or hearing?

No. Plan K only helps with costs that Original Medicare covers. It doesn’t cover routine dental, vision, or hearing care. You can buy separate dental or vision plans if you need them.

Can I use Plan K with any doctor?

Yes. You can see any doctor or hospital in the U.S. that accepts Medicare. There’s no network to worry about, and you don’t need a referral to see a specialist.

Does the Part B deductible count toward my out-of-pocket limit?

To get 100% coverage, you need to reach the yearly limit and pay your Part B deductible. Your share of covered Part A and Part B costs adds up toward the cap. Medicare doesn’t cover certain services, and Part B excess charges don’t count.

Does the out-of-pocket limit reset each year?

Yes. It resets every January 1. The limit itself also changes each year to keep up with rising costs. It’s $8,000 in 2026 and $8,360 in 2027.

When is the best time to buy Plan K?

The best time is during your Medigap Open Enrollment Period. It’s a 6-month window. It starts the first month you are 65 or older and enrolled in Part B. During this time, companies can’t turn you down or charge you more because of your health. After this window closes, most states allow companies to review your health history before selling you a plan.

Can I have Plan K and a Medicare Advantage plan at the same time?

No. Medigap plans only work with Original Medicare. If you have a Medicare Advantage plan (Part C), you can’t use a Medigap plan.

Does Plan K cover my spouse?

No. Each Medigap plan covers just one person. If you and your spouse both want Plan K, you’ll each need your own plan. Some companies offer a discount when you both sign up.

Is Plan K the same as Medicare Part K?

Medicare has Parts A, B, C, and D. Plan K is a Medigap plan that works alongside Parts A and B.

The Bottom Line: Is Medicare Plan K Right for You?

So, what does Medicare Plan K cover? Here’s my short recap:

• It pays 100% of hospital coinsurance and gives you 365 extra hospital days.
• It pays 50% of your Part A deductible, Part B coinsurance, blood, hospice, and skilled nursing costs.
• It does not pay the Part B deductible, excess charges, or foreign travel emergencies.
• It has a yearly cap of $8,000 in 2026 and $8,360 in 2027. After that, it pays 100%.

I think of Plan K as a “save now, share later” plan. You keep your monthly bills low. In return, you agree to share the costs when you need care. And if things get really bad, the cap keeps you from going broke.

If you’re healthy, have some money saved, and like the idea of a lower premium, Plan K is worth a close look. If you’d rather pay more each month to avoid surprise bills, Plan G or Plan N might suit you better.

Whatever you choose, take your time. Compare prices from a few companies. And if you want free, unbiased help, reach out to your local State Health Insurance Assistance Program (SHIP). You can find yours on Medicare.gov. They’ll walk you through your options at no cost.

Why choose Steve Turner Insurance Specialist?

Because I’m an “Insurance Specialist.” An “insurance specialist” is a broad term that includes insurance agents and insurance brokers, but the key difference is who the agent represents versus who the broker represents.

An “insurance agent” works directly for an insurance company and sells its specific policies to clients.

An “insurance broker” acts as an independent intermediary, comparing policies from multiple companies to find the best fit for their client’s needs, essentially representing the client rather than the insurance company.

I am both a licensed Insurance Agent and a licensed Insurance Broker.

My number one goal in life is to help people and ensure, without a shadow of a doubt, that you and your family are secure and protected. I will always be by your side, helping you mitigate risk by providing the industry’s best and most affordable insurance solutions.

The companies that sell the insurance plans “you choose“ pay me – you don’t pay me. Calling any big insurance company directly won’t get you a lower price, as they will forward your call to the next available insurance agent on their list. You won’t have had any opportunity to learn about the insurance agent you’re speaking with in advance, understand their qualifications or experience level, or make an informed choice about who you want to work with.
