What Does Medicare Plan F Coverage Include in 2026?

Key Takeaways

• Plan F enrollment is restricted starting 2026: only those eligible for Medicare before January 1, 2020 can buy it; those eligible after that date cannot enroll, though current holders can keep their coverage.
• Plan F covers Part B deductible and excess charges—unlike most Medigap plans—making out-of-pocket costs highly predictable for frequent doctor visits and primary care.
• Plan F does not cover prescription drugs, routine dental/vision care, hearing aids, or long-term custodial care, requiring separate Part D enrollment and additional coverage for these services.
• Plan F works only with Original Medicare (Parts A & B) and cannot be combined with Medicare Advantage plans, limiting your choice to either one path or the other.
• Premiums for Plan F vary significantly by insurer, location, and age despite identical standardized benefits, making premium comparison essential before enrollment.
• The Medigap Open Enrollment Period is a one-time six-month window starting at age 65 with Part B enrollment; missing it may trigger medical underwriting and potential coverage denials based on health history.

Medicare Plan F coverage has long been described as the most complete Medigap option available. For people who see a primary care doctor often, it can make health costs far easier to predict. But in 2026, the rules around who can buy it have changed, and many people are unsure where they stand.

Plan F works alongside Original Medicare. It pays most of the costs that Medicare leaves behind, including deductibles, coinsurance, and copayments. It does not add new benefits, and it does not replace Medicare's rules. Knowing the difference helps you plan your care with confidence.

This guide explains what Medicare Plan F coverage includes, what it leaves out, who can still enroll, and how it affects primary care and preventive visits. Whether you are a new Medicare member, a current Plan F holder, or a family member helping a parent, you will find clear answers below.

What Is Medicare Plan F?

Medicare Plan F is a standardized Medigap policy, also called Medicare Supplement Insurance. Private insurers sell it, but the benefits are the same no matter which company you choose. Prices, however, can differ a lot.

Plan F pairs with Original Medicare, which means Part A and Part B. You generally need both parts to buy a Medigap policy. It does not work with Medicare Advantage. If you are in a Medicare Advantage plan, a Medigap policy cannot be used alongside it.

According to MedPAC, about 12.4 million beneficiaries were enrolled in Medigap plans in 2024. That is roughly one in four people with Medicare. Plan F has been one of the best-known choices among them.

What Does Medicare Plan F Coverage Include?

Plan F covers nearly all of the cost-sharing that Original Medicare leaves to you. After Medicare pays its share of an approved service, Plan F pays most of what remains.

Core Benefits Covered by Plan F

• Medicare Part A deductible
• Part A coinsurance and hospital costs
• Part A hospice care coinsurance or copayments
• Skilled nursing facility coinsurance
• Medicare Part B deductible
• Part B coinsurance or copayments
• Part B excess charges
• The first three pints of blood
• Emergency care during foreign travel, up to plan limits

The Part B deductible is what sets Plan F apart. Many other Medigap plans leave you to pay it yourself. With Plan F, you generally do not pay it, which keeps your out-of-pocket costs lower during a busy year of doctor visits.

Quick Reference Table

What Medicare Plan F Does Not Cover

Plan F is broad, but it has limits. It only helps with services that Original Medicare already approves. Several common needs fall outside its reach.

• Prescription drugs, which require a separate Part D plan
• Routine dental care
• Routine vision care and eyeglasses
• Hearing aids
• Long-term custodial care

Plan F also has no annual out-of-pocket limit. Because it covers almost all cost-sharing, this rarely matters for covered services. Still, it is worth knowing that the policy is not built the same way as some other health plans.

Premiums are paid in addition to your regular Part B premium. They vary by insurer, location, age, and the way the company sets its rates.

Can You Still Enroll in Plan F in 2026?

This is the question most people ask. The answer depends on when you first became eligible for Medicare.

Federal law bars insurers from selling Medigap plans that cover the Part B deductible to people newly eligible for Medicare on or after January 1, 2020. That includes Plan F. So if you became eligible in 2020 or later, you generally cannot buy it.

If you were eligible before that date, you may still be able to buy Plan F. Availability depends on your state and on whether an insurer is selling it.

Who Can Have Plan F Today

1. Current policyholders: If you already have Plan F, you can generally keep it.
2. People eligible before 2020: You may be able to buy it, even if you never enrolled before.
3. People newly eligible on or after January 1, 2020: You generally cannot buy Plan F.

If you are buying Plan F outside of a protected enrollment window, an insurer may be allowed to review your health history. This is called medical underwriting. Rules differ by state, so check with your state insurance department or a licensed advisor.

High-Deductible Plan F

Some people can also choose a high-deductible version of Plan F. For 2026, Medicare.gov lists the deductible at $2,950. You pay that amount first before the policy begins to pay benefits. Premiums are often lower, but you take on more risk early in the year.

How Plan F Works With Primary Care

Plan F does not provide a doctor or a care network. It does not choose a provider for you. What it does is reduce your share of Medicare-approved costs after Original Medicare pays its part.

For primary care, that can mean little or no bill after a covered office visit. You can see any doctor who accepts Medicare, which gives you flexibility. The provider must accept Medicare for the claim to work as expected.

This is where a strong primary care relationship matters. A coordinated, prevention-focused practice can help you use your coverage well. At InCare primary care, patients receive comprehensive care for chronic and acute conditions with a focus on prevention. If you want guidance on choosing a provider, our guide on the traits of the best Medicare provider for primary care is a helpful place to start.

Preventive Visits and Plan F

Medicare covers certain preventive services under Part B when you meet eligibility and provider rules. These include the Welcome to Medicare visit and the annual wellness visit. Plan F may cover your applicable cost-sharing for these services.

It is important to know what the annual wellness visit is and is not. It is a planning visit, not a head-to-toe physical exam. Plan F does not make non-covered services covered, and it does not turn a wellness visit into a routine physical. To learn more, read what happens during an annual wellness visit. You can also learn how a Medicare doctor supports your health year after year.

Plan F vs. Plan G for Primary Care Costs

Plan G is the closest comparison, and it is open to people newly eligible for Medicare. The two plans are nearly identical. The main difference is the Part B deductible.

With Plan G, you pay the Part B deductible once each year. After that, your costs for covered services are generally covered. Many people find the lower premium offsets that one-time cost. For a deeper look at options, see our overview of what Medicare covers for seniors in primary care.

Plan F vs. Medicare Advantage

These two paths work in very different ways. Plan F adds to Original Medicare and lets you see any doctor who accepts Medicare. Medicare Advantage replaces Original Medicare and often uses a provider network.

Neither is right for everyone. Plan F tends to offer predictable costs and wide provider choice. Advantage plans may offer lower premiums and extra benefits but can limit your network. You can read more in our guide to Medicare Advantage plans and primary care.

Understanding Your Enrollment Window

Timing matters when you buy a Medigap policy. The Medigap Open Enrollment Period is a one-time, six-month window. It begins when you are both age 65 or older and enrolled in Part B.

During this period, insurers generally cannot deny you coverage or charge more because of your health. It is not an annual event. Once it ends, you may face medical underwriting in many states. If you are approaching Medicare eligibility, plan ahead.

Tips for Getting the Most From Your Coverage

1. Confirm eligibility first. Check your Medicare start date before shopping for Plan F.
2. Compare premiums. Benefits are the same, but prices vary widely between insurers.
3. Add drug coverage. Plan F does not cover prescriptions, so consider a Part D plan.
4. Choose a doctor who accepts Medicare. This keeps claims simple and costs low.
5. Use preventive services. Screenings and wellness visits catch problems early.

Preventive care is where good coverage and a good doctor work together. Learn how to make preventive care work for your health, and explore cancer screening options that support early detection.
