Medicare Plan F

Reviewed by Russell Noga, Licensed Medicare Insurance Broker (all 50 states) | Last updated October 8, 2026

Medicare Plan F is the Medigap plan that covers every standard gap in Original Medicare, including the Part B deductible, but it is only available to people first eligible for Medicare before January 1, 2020.

If you became eligible on or after that date, Plan G is the closest option: it covers everything Plan F does except the Part B deductible. If you already have Plan F, you can keep it as long as you pay your premiums.

High-Deductible Plan F

High-Deductible Plan F covers the same benefits as Plan F after you pay a yearly deductible of $3,050 in 2027, up from $2,950. It has a much lower premium and suits people who want catastrophic protection, but it carries the same pre-2020 eligibility rule.

Should You Switch From Plan F to Plan G?

Step by Step

1

Get a Plan G quote for the same insurer and others. Compare the yearly premium difference.

2

Subtract the Part B deductible. Plan G makes you pay it; the 2026 amount is $283.

3

Check whether you must answer health questions. Outside guaranteed issue, most insurers in most states can underwrite.

4

Keep Plan F until a new policy is approved. Never cancel coverage first.

When to Buy

Be aware: once your six-month Medigap Open Enrollment Period has passed, and without a guaranteed issue right, insurers in most states may ask health questions and turn you down or charge you more.

Guaranteed issue: when your Medicare Advantage plan exits your area, you can generally purchase certain Medicare Supplement plans with no health questions asked, up until 63 days after that coverage ends.

Help Paying Medicare Costs

When your income and savings are limited, two programs can greatly lower your Medicare costs:

Medicare Savings Programs

✔

Run by your state Medicaid office

✔

May cover your Part B premium, and in some cases deductibles and coinsurance

✔

Income and asset limits vary by state

Extra Help (Part D)

✔

Run by Social Security

✔

Lowers Part D premiums, deductibles and copays

✔

Those enrolled in a Medicare Savings Program qualify automatically

If you qualify for both Medicare and full Medicaid, you may also be able to join a Dual Special Needs Plan. See help for low-income Part D beneficiaries.

What Original Medicare Leaves You to Pay

Original Medicare leaves gaps, and a Medicare Supplement plan is designed to fill them. It can pay these costs:

Original Medicare Gap What It Means for You Covered By
Part A deductible Applied each hospital benefit period instead of annually. The 2026 amount was $1,736. Plans B, C, D, F, G and N fully; K, L and M partially
Part A hospital coinsurance Daily charges after day 60 of a hospital stay, which climb after day 90 All 10 plans, plus 365 extra hospital days
Part B deductible An annual deductible owed before Part B pays. In 2026, $283. Only Plans C and F
Part B coinsurance Typically 20% of the approved amount, with no annual cap All plans (K and L in part, N with copays)
Part B excess charges As much as 15% over the approved amount from doctors who do not accept assignment Plans F and G
Skilled nursing coinsurance Daily charges for days 21 through 100 of a covered stay Plans C, D, F, G, M and N (K and L in part)
Emergency care abroad Care outside the U.S. is generally not covered by Original Medicare. Plans C, D, F, G, M and N, up to plan limits

No limit unless you add a supplement: Original Medicare does not have an out-of-pocket maximum. If you lack a Medigap plan or other coverage, the 20% you may owe on Part B services has no ceiling.

*Only people who became eligible for Medicare before January 1, 2020, can buy Plans C and F. **Plans K and L come with a yearly out-of-pocket limit that Medicare updates each year; once you hit it, the plan covers 100% of covered services for the remainder of the year. ***Plan N covers all Part B coinsurance apart from copays of up to $20 for certain office visits and up to $50 for ER visits that do not result in an inpatient admission. Massachusetts, Minnesota and Wisconsin use their own way of standardizing plans.

Plan G, Plan N and High-Deductible Plan G

Most people new to Medicare choose one of these three. Plan G covers every gap except the Part B deductible. Plan N trades a lower premium for copays of up to $20 for some office visits and up to $50 for ER visits that do not lead to admission, and it does not cover Part B excess charges. High-Deductible Plan G has a $3,050 deductible for 2027, up from $2,950, then covers like Plan G. See Plan G vs Plan N.

Plan G

✔

After the Part B deductible, you pay little or nothing

✔

Covers Part B excess charges

✔

Highest premium of the three

Plan N

✔

You pay the Part B deductible plus small copays

✔

Does not cover Part B excess charges

✔

Usually a lower premium than Plan G

High-Deductible G

How Medigap Prices Are Set

Your Age

Many insurers charge more as you get older.

Your ZIP Code

Prices vary by state and area.

Tobacco Use

Tobacco users usually pay more.

Discounts

Household or other discounts, which vary by insurer and state.

Pricing Method How the Premium Is Set Over Time
Community-rated All people in an area pay one premium, whatever their age Does not go up as you age, but may go up for inflation and other reasons
Issue-age-rated Based on your age when you buy Does not go up as you age, but may go up for other reasons
Attained-age-rated Based on your current age Rises as you age, on top of other increases

Which method applies depends on the insurer and the state. Before buying, find out how a policy is priced, not only what it costs now.

What Medigap Does Not Cover

Not Covered by Medigap

✔

Prescription drugs: add a standalone Part D plan

✔

Routine dental care, hearing aids, and eye exams for glasses

✔

Long-term custodial care, whether in a nursing home or at home

✔

Private-duty nursing

In 2027, a standalone Part D plan can have a deductible of no more than $700 and an out-of-pocket cap of $2,400. Buy it with Medigap to avoid a late enrollment penalty that lasts for life.

Medigap vs Medicare Advantage

Medicare Advantage Original Medicare + Medigap
Monthly premium Often low or $0 (2027 average $12, CMS) Higher; varies by plan letter, age and ZIP
Doctors Usually a network Any provider in the U.S. that accepts Medicare
Costs when you get care Copays and coinsurance up to a yearly maximum Low and predictable; on Plan G, little or nothing once the Part B deductible is met
Drug coverage Usually included Add a separate Part D plan
Dental, vision, hearing Many plans may include some coverage Not included
Changing later Every year during Annual Enrollment Health questions in most states once your Medigap Open Enrollment Period ends

Plans K and L: Lower Premiums With a Cost Cap

Rather than paying all of most costs, Plans K and L pay a portion: Plan K covers 50% and Plan L covers 75% of most cost sharing, leaving the remainder to you. In return for their lower premiums, both carry an annual out-of-pocket limit set by Medicare each year. After you hit that limit, the plan covers 100% of covered services for the remainder of the year.

These plans may fit people who want catastrophic protection for a lower premium and can manage some costs along the way. Check whether your insurer sells Plan K or L in your state.

Plans C and F for Earlier Enrollees

Only Plans C and F cover the Part B deductible. Since January 1, 2020, they have not been sold to people newly eligible for Medicare. If you became eligible for Medicare before that date, even without enrolling, you may still be able to purchase Plan C or F, including a High-Deductible Plan F that has the same $3,050 deductible for 2027.

For most people eligible to buy either, set the yearly premium gap between Plan F and Plan G against the Part B deductible. If the extra cost of Plan F exceeds what it saves you on the deductible, Plan G is the better value.

Medigap Under 65

If disability or end-stage renal disease gives you Medicare before 65, federal law does not make insurers sell you a Medigap policy, though many states require it. Prices for those under 65 can run much higher, and plan options may be limited. At 65, you get a fresh six-month Medigap Open Enrollment Period, during which you can buy any plan sold in your state at the same prices others your age pay.

Medigap When You Travel

Within the U.S., a Medigap plan goes wherever you go, since it works with any provider that accepts Medicare. Abroad, Original Medicare generally pays nothing, but Plans C, D, F, G, M and N pay 80% of emergency care outside the U.S. after a $250 annual deductible, up to a $50,000 lifetime limit.

Rate Increases and Switching Insurers Later

Once you buy Medigap, its benefits never change, but its premiums can. Insurers submit rate increases to state regulators, frequently once a year. Since the same plan letter has the same benefits everywhere, moving to a cheaper insurer can cut costs while your coverage stays the same.

The drawback is underwriting. Outside your Medigap Open Enrollment Period or a guaranteed issue situation, most states allow the new insurer to ask health questions and turn you down. Do not cancel your current policy until the new one has been approved and is in force.

How Medigap Claims Work

Usually you won’t ever file a Medigap claim. Your doctor sends the bill to Medicare, Medicare pays its portion, and the claim passes automatically to your Medigap insurer, which then pays its portion. A Medicare Summary Notice and an explanation of benefits show you what each one paid.

Medigap and Part D Together

Medigap plans sold now don’t include prescription coverage, so you should add a Part D plan as well. It doesn’t need to come from your Medigap insurer. Pick it based on your drugs and pharmacy in Medicare Plan Finder and look it over each fall. If you put off drug coverage with no other creditable coverage, the late penalty adds 1% of the national base beneficiary premium, $41.33 for 2027, for each month you were without it.

Turning 65 in 2027

When you turn 65 in 2027, you get a seven-month Initial Enrollment Period: the three months before your birthday month, the birthday month itself and the three months that follow. If you sign up in the first three months, coverage begins on the first day of your birthday month.

Turning 65 Checklist

✔

Enroll in Part A and Part B, unless you have qualifying employer coverage and decide to postpone Part B

✔

Choose between Medicare Advantage and Original Medicare plus Medigap

✔

Enroll in a drug plan, or a Medicare Advantage plan that includes drugs, to avoid a late Part D penalty

✔

If you go with Medigap, purchase during your six-month Medigap Open Enrollment Period

Frequently Asked Questions

➤ What does Medicare Plan F cover?

Plan F covers all standard Medigap benefits: the Part A deductible and coinsurance, Part B coinsurance, the Part B deductible, Part B excess charges, skilled nursing coinsurance, the first 3 pints of blood and 80% of foreign travel emergencies up to plan limits.

➤ Can I still buy Medicare Plan F?

Only if you were first eligible for Medicare before January 1, 2020. People who became eligible on or after that date cannot buy Plan F or Plan C, but they can buy Plan G, which covers everything Plan F does except the Part B deductible.

➤ Can I keep my Plan F?

Yes. Medigap policies are guaranteed renewable, so you can keep your Plan F as long as you pay your premiums. Your insurer cannot cancel it because of your health, though premiums can still rise over time.

➤ What is the difference between Plan F and Plan G?

The only benefit difference is the Part B deductible: Plan F pays it and Plan G does not. The 2026 Part B deductible is $283, so compare that amount with the yearly premium difference between the two plans.

➤ What is High-Deductible Plan F?

High-Deductible Plan F covers the same benefits as Plan F after you pay a $3,050 deductible in 2027, up from $2,950. Its premium is much lower, and it has the same pre-2020 eligibility rule as standard Plan F.

➤ Should I switch from Plan F to Plan G?

Switching can save money if the premium savings exceed the Part B deductible, but in most states you must pass health questions. Get quotes first and keep Plan F until a new policy is approved, so you are never left without coverage.

➤ Does a Medicare Supplement plan cover prescription drugs?

No. Medigap plans do not include Part D drug coverage, so you add a separate Part D plan. For 2027 the Part D deductible can be up to $700 and the out-of-pocket cap on covered drugs is $2,400.

➤ How are Medigap premiums priced?

Insurers use one of three methods: community-rated, where everyone pays the same regardless of age; issue-age-rated, based on your age when you buy; or attained-age-rated, which rises as you get older. Ask which method a policy uses, because it shapes what you pay over the long run.

➤ Are Medigap benefits the same with every insurer?

Yes. Medigap plans are standardized by letter, so a Plan G from one insurer covers the same benefits as a Plan G from any other insurer in your state. The differences are price, pricing method, rate history and customer service, which is why comparing quotes matters.
