What Is Medicare Supplement Plan F?

Medicare Plan F gives you the most benefits of any of the 10 Medicare Supplement plans.

Medicare Supplement Plan F will cover all of your medical costs after Original Medicare pays its portion of the bill. This means you won't have to pay anything for medical treatment.

Plan F is popular, and it's expensive. The average cost of Plan F is $184 per month, which is on top of the $174.70 per month you pay for Medicare Part B.

If you are new to Medicare, meaning you became eligible in January of 2020 or later, you can't sign up for Plan F. Instead, choose Plan G, which has benefits that are nearly as good as Plan F's.

What is Medicare Plan F?

Medicare Supplement Plan F (also called Medigap Plan F) is an add-on to Original Medicare that you get through the government.

For any type of medical treatment that's covered by Original Medicare, Medigap Plan F will pay the rest of your bill, leaving you with $0 costs.

This means that Plan F pays for doctor appointments, hospitalization and medical treatment. But it won't pay for dental care or prescription drugs, which aren't covered by Original Medicare. It also won't pay for your monthly costs for Medicare.

Is Medicare Supplement Plan F still available?

Since January 2020, new Medicare enrollees have not been able to buy Medigap Plan F. However, you can still buy a plan or keep your plan if you were eligible for Original Medicare before Jan. 1, 2020.

Plan F was discontinued for new enrollees because of legislation to end plans that provide 100% free health care. When medical care is completely free, some enrollees would see the doctor for minor issues, and the Medicare program was paying for the extra appointments.

How much does Medicare Plan F cost?

Medicare Supplement Plan F costs an average of $184 per month for 2024.

The cost of Plan F varies widely based on your location, age, gender, when you sign up, the company and sometimes your health status.

How to save on Plan F

You'll get the best deal on Medicare Supplement plans if you sign up for a plan during the open enrollment period when you first become eligible for Medicare.

  • During this time, you could get discounted rates called preferred pricing.
  • You also won't have to answer questions about your medical history. This means you won't pay more or have your application denied if you have a chronic medical condition.

What other costs do you have with Medigap Plan F?

With Plan F, you'll still have to pay for any costs that are not covered by Original Medicare, such as medications.

Plan F won't pay for:

  • Prescription drugs
  • Vision and dental care (usually)
  • Hearing aids and routine hearing exams

Prescription drugs aren't covered by either Plan F or Original Medicare. Many people get drug coverage by adding on a Medicare Part D plan.

You can also buy stand-alone dental insurance and vision plans.

What is a high-deductible Medicare Plan F?

High-deductible Medigap Plan F has the same benefits as the standard Plan F policy, but you must meet a $2,800 deductible before it starts paying.

High-deductible Plan F is similar to catastrophic coverage because it won't pay for your expenses in years when you need routine or moderate amounts of health care. But in a year when you need expensive medical care, it will protect you from very high medical costs.

High-deductible Plan F costs $52 per month, on average. That's $132 per month cheaper than standard Plan F.

For 2024, high-deductible Plan F has a deductible of $2,800. So after you pay $2,800 in medical expenses, the Medigap plan will kick in to pay for all medical costs after that point. Before you meet the $2,800 deductible, you'll only have Original Medicare coverage.

If you have Original Medicare without supplemental coverage, you could have unlimited medical costs because you won't have a cap on your medical spending, called an out-of-pocket max.

How to buy Medicare Plan F

Buy Medicare Plan F by shopping directly with an insurance company or broker.

  1. Find out if you qualify for Plan F by checking if you were eligible for Medicare prior to 2020.
  2. Use Medicare.gov's plan comparison tool to see which companies are offering plans in your area.
  3. Shop around and compare quotes from different companies. Remember that Plan F will have the same benefits no matter what company you buy it from. So choosing one of the top Medicare Supplement companies can help you get cheap rates and good customer service.
  4. Remember to buy a Medigap policy when you're first eligible. It's easiest and cheapest to get a policy during the six-month period after you first enroll in Medicare Part B after age 65.

Once you have Medigap, you are always able to renew your plan. Plus the insurance company can't cancel your policy, unless you stop paying.

But if you sign up late or want to change your Medigap plan, you may have to pay higher rates or your application could be denied by the insurance company. That's because in many cases, you'll have to answer questions about your medical history.

Are Medicare Plan F premiums tax-deductible?

Yes, the cost for Medicare Plan F is tax-deductible if you itemize your deductions or are self-employed.

  • If you're itemizing your deductions, you usually won't be able to deduct the full amount that you're paying for your Medicare Supplement plan. Instead, you'll only be able to deduct your combined costs for insurance and medical care that are more than 7.5% of your income.
  • If you're self-employed, you can deduct the full cost of Medicare Plan F and other health insurance costs. These costs are treated as a write-off to your business, so they reduce the amount of income that you pay taxes on.

What is the difference between Medicare Plans F and G?

Medicare Plan F covers more of your medical costs and is more expensive than Plan G.

There are three main differences between Plans F and G.

  • Plan F is more expensive: Plan F costs $36 more per month than Plan G, on average. That's about $432 more per year.
  • Plan F covers more medical costs: Plan F pays for the Part B medical deductible, but Plan G doesn't. This means with Plan G, your medical costs would be $240 higher than with Plan F.
  • Fewer people can get Plan F: New Medicare enrollees can't sign up for Plan F because you have to have been eligible for Medicare before 2020 to qualify. There are no enrollment restrictions for Plan G.

Plans F and G are very similar. And because Plan F only covers $240 more of your medical expenses than Plan G, it's not always a better deal.

If you're deciding between Plan F and Plan G, it's only worth it to pay for Plan F if it costs less than $20 more per month than Plan G. Otherwise, it's a better deal to choose Plan G and pay the extra $240 for medical care.
