If Medigap plans had yearbook superlatives, Medicare Supplement Plan F would win “Most Likely to Cover the Tab”. For people who are eligible to buy it, Plan F is the most comprehensive standardized Medicare Supplement plan on the market. It helps pay nearly all of the out-of-pocket costs left behind by Original Medicare, which is why it has long been a favorite among people who want predictable medical bills and as few surprises as possible.
But there is a catch, and it is a big one: not everyone can buy Plan F anymore. If you became newly eligible for Medicare on or after January 1, 2020, Plan F is generally off the menu. If you were eligible before that date, however, Plan F may still be available to you depending on your situation, your state, and whether you are applying during a protected enrollment window or subject to underwriting.
So what does Medicare Supplement Plan F actually cover? In plain English, it picks up the deductibles, copayments, and coinsurance that Original Medicare often leaves you to handle. That includes the Part A deductible, the Part B deductible, Part B coinsurance, skilled nursing facility coinsurance, hospice cost-sharing, excess charges, and even limited foreign travel emergency coverage. In other words, Plan F is the Medigap plan that likes to show up with snacks, a charger, and a backup charger.
The Quick Answer: What Plan F Covers
Medicare Supplement Plan F covers the broadest set of standardized Medigap benefits available in most states. Once Medicare approves and pays its share of a covered service, Plan F is designed to cover your remaining share for many common costs under Original Medicare.
- Medicare Part A coinsurance and hospital costs for up to 365 extra days after Medicare benefits are used up
- Medicare Part B coinsurance or copayments
- The first 3 pints of blood
- Part A hospice care coinsurance or copayments
- Skilled nursing facility care coinsurance
- Medicare Part A deductible
- Medicare Part B deductible
- Medicare Part B excess charges
- Foreign travel emergency coverage at 80% up to plan limits
That last item matters more than many people realize. If you are the sort of person who likes to escape winter by chasing sunshine in another country, Plan F gives you some emergency travel protection that Original Medicare usually does not provide outside the U.S. It is not unlimited global health insurance, but it is a useful layer of backup.
What Each Plan F Benefit Really Means
1. Part A Hospital Coinsurance and 365 Extra Hospital Days
Original Medicare Part A helps cover inpatient hospital care, but it does not promise endless hospital coverage with zero cost-sharing. Plan F pays your Part A coinsurance and can also cover up to 365 additional days in the hospital after Medicare benefits are exhausted. That is one of the reasons people often describe Plan F as “peace-of-mind coverage.”
Example: if you have a long hospital stay or a complicated recovery, Plan F can protect you from large hospital cost-sharing that would otherwise land in your lap like an unwelcome holiday fruitcake.
2. Part B Coinsurance or Copayments
Under Original Medicare, Part B usually leaves you responsible for 20% of the Medicare-approved amount for many outpatient services after you meet the Part B deductible. That includes doctor visits, specialist care, outpatient surgery, durable medical equipment, and more. Plan F covers that Part B coinsurance or copayment amount.
This is a major reason Plan F has historically been so attractive. If you see doctors often, need imaging, visit specialists, or have recurring outpatient treatments, those 20% pieces can add up fast.
3. The First 3 Pints of Blood
It sounds oddly specific because it is. Medicare does not automatically pay for the first 3 pints of blood in certain situations. Plan F covers that gap. It is not the flashiest benefit, but it is part of the reason Plan F earns its reputation for thoroughness.
4. Hospice Cost-Sharing
Plan F covers Part A hospice care coinsurance or copayments. This benefit can ease financial stress during a difficult time, when the last thing a family needs is yet another bill arriving in the mailbox like it pays rent there.
5. Skilled Nursing Facility Coinsurance
Original Medicare covers skilled nursing facility care only under certain conditions, and cost-sharing can kick in during extended stays. Plan F covers the skilled nursing facility coinsurance, which can be especially valuable after hospitalization, surgery, or rehabilitation.
6. The Part A Deductible
One of Plan F’s most valuable features is that it covers the Medicare Part A inpatient hospital deductible. In 2026, that deductible is $1,736 per benefit period. That means if you are admitted to the hospital, Plan F can absorb that large upfront cost instead of leaving it on your side of the ledger.
7. The Part B Deductible
This is the benefit that makes Plan F famous. Plan F covers the Medicare Part B deductible, which is $283 in 2026. That may not sound dramatic compared with a hospital bill, but it is the reason Plan F is no longer available to people newly eligible for Medicare on or after January 1, 2020.
Why? Because federal law changed the rules so newly eligible beneficiaries cannot buy Medigap plans that pay the Part B deductible. Since Plan F does pay it, access to the plan is now limited to older eligibility groups.
8. Part B Excess Charges
Some doctors do not accept Medicare assignment, which means they can charge more than the Medicare-approved amount up to a legal limit in certain situations. Those extra amounts are called Part B excess charges. Plan F covers them.
If you live in an area where non-participating providers are more common, or you want the freedom to see a broader mix of physicians without worrying about excess charges, this feature can be a big deal.
9. Foreign Travel Emergency Coverage
Plan F covers 80% of foreign travel emergency care up to plan limits, after you meet the plan’s foreign travel deductible. This is not a substitute for full travel insurance, but it is a useful benefit for retirees who travel abroad, split time between countries, or simply do not want to feel financially naked at 30,000 feet.
What Plan F Does Not Cover
Plan F is broad, but it is not magic. It only supplements services that Original Medicare covers. If Medicare does not cover the service, Plan F generally does not either.
That means Plan F generally does not cover:
- Prescription drugs, which usually require a separate Part D plan
- Routine dental care
- Routine vision care or eyeglasses
- Hearing aids
- Long-term custodial care
- Private-duty nursing
You also still pay your monthly Medicare Part B premium and your separate Medigap premium. So while Plan F can reduce your out-of-pocket costs when you receive care, it does not mean healthcare becomes free. It just becomes much more predictable.
Who Can Buy Medicare Supplement Plan F?
This is where things get a little less “easy answer” and a little more “fine print with coffee.” In most cases, you can buy Plan F only if you were eligible for Medicare before January 1, 2020. That can include people who became eligible by age as well as some people who qualified earlier because of disability.
If you already have Plan F, you can generally keep it as long as you continue paying your premiums. If you were eligible for Medicare before 2020 but delayed enrollment, you may still be able to apply for Plan F later. Whether you can get it without medical underwriting depends on your timing and your rights under federal and state rules.
Your best buying window is typically your six-month Medigap Open Enrollment Period, which begins when you are 65 or older and enrolled in Medicare Part B. During that window, insurers generally cannot deny you coverage or charge you more because of health conditions. Outside that period, you may face underwriting unless you have a guaranteed issue right.
How Plan F Works with Original Medicare
Plan F is not a replacement for Medicare. It works alongside Original Medicare. First, Medicare pays its approved share of a covered service. Then Plan F pays its share of the remaining covered costs according to the plan design.
You must be enrolled in Original Medicare Part A and Part B to buy a Medigap plan. You also cannot use Medigap with Medicare Advantage. It is one path or the other. Think of it like choosing between two roads: Original Medicare plus Medigap on one side, Medicare Advantage on the other. Both can work well, but they are not stackable like pancakes.
Are Plan F Benefits the Same from One Company to Another?
Yes, in most states, Plan F benefits are standardized. That means a Plan F from one insurer must provide the same core medical benefits as a Plan F from another insurer. The big differences are usually:
- Monthly premium
- Customer service
- Rate increase history
- Household discounts or other pricing features
- Availability of extras that are not part of the standardized Medigap medical benefits
The standardization rule is one of the most consumer-friendly parts of Medigap. You are not comparing a dozen mystery boxes with shiny brochures. You are usually comparing the same lettered benefits at different prices. The major exceptions are Massachusetts, Minnesota, and Wisconsin, where Medigap policies are standardized differently.
What About High-Deductible Plan F?
In some states, a high-deductible version of Plan F is available for people who are eligible to buy Plan F. The benefits are the same as standard Plan F, but the plan does not begin paying until you meet the annual high deductible.
For 2026, the high deductible is $2,950. There is also a separate $250 annual deductible for foreign travel emergency care. The trade-off is simple: lower monthly premiums in exchange for higher upfront exposure before the plan starts helping.
High-deductible Plan F can make sense for people who want the protection of Plan F’s benefit design but do not expect heavy use of medical services every year. It can be a budget strategy, not a downgrade in covered benefits.
Plan F vs. Plan G: The Comparison Everyone Ends Up Making
If you are shopping for Medigap and Plan F is available to you, you will almost certainly compare it with Plan G. And you should. Plan G covers nearly everything Plan F covers except the Part B deductible.
So the core math question becomes this: is the extra premium for Plan F worth more than the Part B deductible it saves you? In 2026, that deductible is $283. If the annual premium difference between Plan F and Plan G is much higher than that amount, Plan G may offer better value. If the difference is small and you prefer the simplicity of having virtually every major Original Medicare cost-sharing bucket covered, Plan F may still feel more comfortable.
That is why Plan F is often described as the “maximum coverage” option, while Plan G is often described as the “best value” option. Neither description is universally true for every person, but they are useful starting points.
When Plan F May Be a Good Fit
- You were eligible for Medicare before January 1, 2020
- You want the broadest standardized Medigap coverage available
- You prefer predictable costs over lower premiums
- You see doctors frequently or expect regular outpatient care
- You want protection from Part B excess charges
- You travel and like having limited foreign emergency coverage
When Plan F May Not Be the Best Fit
- You are newly eligible for Medicare and cannot buy it
- You want the lowest possible premium
- You are comfortable paying the Part B deductible yourself and considering Plan G
- You want benefits like dental, vision, or drug coverage built into one plan
- You are comparing Medigap against a Medicare Advantage plan with different trade-offs
Real-World Experiences with Medicare Supplement Plan F
Ask people why they like Plan F, and the answer is rarely a dramatic speech about actuarial design. It is usually something more practical, like, “I just don’t want surprise bills.” That is the heart of the Plan F experience.
Take the retiree who sees a primary care doctor, a cardiologist, and an orthopedic specialist several times a year. With Original Medicare alone, those appointments can create a steady drip of 20% cost-sharing after the Part B deductible. It may not look scary at first glance, but it adds up over time. For someone in that situation, Plan F often feels less like an insurance upgrade and more like turning chaotic invoices into a smoother monthly budget.
Then there is the hospital story. A person may go years without major issues, and then one surgery, one unexpected admission, or one rehab stay suddenly reminds them that Medicare has gaps. People who have Plan F often describe a sense of relief during these moments because the plan absorbs costs that could otherwise become a painful financial side plot. Nobody wants to compare hospital bills while wearing compression socks.
Travelers also tend to appreciate Plan F differently. A retired couple taking international trips may know the foreign emergency benefit is limited, but they still like having some protection instead of none. It is not a substitute for comprehensive travel medical insurance, yet it can make people feel less exposed when they are far from home and even farther from their usual pharmacy.
Another common experience involves choice. Many Medigap users value the freedom to see any doctor who accepts Medicare without worrying about networks or referrals. For people who split time between states, spend winters elsewhere, or simply want flexibility, Plan F can feel refreshingly simple. No hunting through provider directories. No wondering whether a specialist is “in network.” Just Medicare first, then the supplement.
Of course, Plan F is not always the winner in every household. Some people eventually look at their premiums and wonder whether Plan G would have given them nearly the same protection for less money. That is a fair question. But even then, many long-time Plan F members stay put because they value the familiarity, the coverage level, and the comfort of knowing the Part B deductible is already handled. In insurance terms, that may sound boring. In real life, boring can be beautiful.
Final Thoughts
Medicare Supplement Plan F covers more than any other standardized Medigap plan sold in most states. For eligible beneficiaries, it pays the major deductibles, coinsurance, copayments, excess charges, and several other gaps left by Original Medicare. It is especially appealing to people who want rich coverage, provider flexibility, and fewer billing surprises.
Still, coverage is only half the story. Availability matters, premiums matter, and timing matters. Because Plan F is generally limited to people who were eligible for Medicare before January 1, 2020, many shoppers today will end up comparing Plan G or other Medigap options instead. But if Plan F is available to you, it remains one of the strongest “sleep-better-at-night” choices in the Medicare Supplement world.
The smartest move is not assuming the richest plan is automatically the best one. It is comparing benefits, premiums, eligibility rules, and your own healthcare habits. In other words, buy the plan that fits your life, not just the letter that looks fanciest in the brochure.
