Original Medicare offers quality coverage, but it leaves a lot of out-of-pocket costs on the table. On average, Medicare beneficiaries paid $5,460 out of pocket on healthcare expenses in 2016, but people without supplemental insurance paid even more ($7,473). This is where Medicare Supplement Plan F and other Medigap plans can be beneficial. These plans pay down the expenses left behind by Part A and Part B, including deductibles, copays, coinsurance, and other out-of-pocket expenses.

With the exception of Massachusetts, Minnesota, and Wisconsin, the federal government standardizes what is included in each lettered Medicare Supplement Plan (Plans A through N). Medicare Supplement Plan F is not only the most comprehensive plan for lowering out-of-pocket costs, it is also the most popular. According to America’s Health Insurance Plans (AHIP) nearly 14 million people on Original Medicare were also on a Medigap plan in 2018 and more than half of them were on Plan F.

Keep reading for help in deciding if Plan F is right for you, and how to select the best Medicare Supplement Plan F provider for your needs.

The 6 Best Medicare Supplement Plan F Providers of 2021


Starting on January 1, 2020, Plan F is not available to people newly enrolled in Medicare. Plan F is still an option if you were eligible for Medicare before that date, whether based on age (65 years or older) or qualifying disability (regardless of age).


Massachusetts, Minnesota, and Wisconsin have state-specific policies and do not offer Medicare Supplement Plan F.


Although Medicare has an annual Open Enrollment Period, there is only one Medigap Open Enrollment Period. This six-month period starts when you enroll in Medicare Part B. Signing up after that time will allow companies to increase your rates or deny you coverage based on preexisting conditions.

Best Overall: Humana



  • 24/7 nurse line

  • High-deductible plans in most states

  • Multiple discount programs

  • User-friendly website and mobile apps

  • Also offers dental, vision, and Part D drug plans

  • Rates increase based on age

  • Rates not available without a quote

Founded in 1961, Humana started out as a nursing home company and began selling health insurance in the 1980s. It offers Plan F in all 47 states where traditional Medicare Supplement Plans are available. High-Deductible Plan F is available in all of those states except Georgia and Kentucky.

To enroll in Humana Plan F, call Monday through Friday or request a telephone appointment using a simple online form on its website. You will need to include your start dates for Medicare Parts A and Part B and your desired start date for Medicare Supplement coverage. Humana requires a formal application for cost estimates and does not provide any rates over the phone. Its pricing, like many other Medicare Supplement companies, is based on attained age. This means you will pay more for your plan as you age. To round out your Medicare coverage, you can also sign up for dental and/or vision coverage not otherwise covered by Original Medicare and consider enrollment in one of its Medicare Part D prescription drug plans, many of which are rated 4-stars and above. 

Not only does Humana have a user-friendly website that's full of helpful Medicare content, but it also has an online portal and a mobile app, myHumana, for easy access to claims and benefits. Other perks include a household discount when two or more enrollees live together (5%), an automatic bank payment discount (variable by state), the 24/7 HumanaFirst® Nurse Advice Line for your medical questions, a basic SilverSneakers gym membership, and discounts on healthcare items not covered by Original Medicare—including hearing aids, medical alert systems, non-prescription medications, and vision exams.

Best Discounts for People New to Medicare: AARP by UnitedHealthcare

AARP by UnitedHealthcare

AARP by UnitedHealthcare

  • Household discounts (5%)

  • New to Medicare Discount (39% off in the first year)

  • Rates do not increase based on age

  • Also offers Part D drug plans

  • No High-Deductible Plan F

  • Requires dues for AARP membership

UnitedHealth Group was founded in 1977 and its insurance arm, UnitedHealthcare, has been in partnership with AARP since 1997.  Combining quality healthcare offerings with one of America’s largest advocacy groups for people over 50, AARP by UnitedHealthcare Medicare Supplement Plans are highly ranked. It offers Plan F, but not High-Deductible Plan F, in all states except for Massachusetts, Minnesota, and Wisconsin.

Enrollment in Medicare Supplement Plan F requires AARP membership, which in 2020 was $12 for first timers and $16 for renewals. Membership comes with added perks, including financial planning services, shopping discounts, and more. Once you are a member, you can reach out to UnitedHealthcare to sign up for Plan F and, if you're interested, one of the company's highly rated Medicare Part D plans for prescription drug coverage. Reach out to a representative seven days a week, or chat with an agent online at its website. The site is easy to use and provides a wealth of information about Medicare and Medicare Supplement Plans. The company did not provide a quote to us over the phone because we were not applying for a plan.

AARP by UnitedHealthcare is unique in that it prices its plans according to a community-based model in the majority of states it services. Regardless of your age or gender, you will pay the same community rate—in other words, your monthly premium will not increase based on your age.

To save even more on Plan F, UnitedHealthcare provides a New to Medicare discount (39% off your first year), a household discount when two or more enrollees live together (5%), an automatic bank payment discount ($2 per month), and a flat discount for pay paying your annual premiums upfront ($24 per year). Be sure to ask for available discounts when you sign up.

Best for Cost and Overall Price Transparency: Aetna



  • 24/7 nurse line

  • Highest household discounts (up to 14%)

  • Also offers dental, vision, and Part D drug plans

  • Rates available online

  • Cannot enroll online

  • Rates increase based on age

Founded in 1853 as a life insurance company, Aetna entered the healthcare market in 1899.

Aetna offers Plan F in 41 states, excluding Alaska, Connecticut, Hawaii, Maine, Massachusetts, Minnesota, New York, Washington, and Wisconsin. High-Deductible Plan F is available in 20 states: California, Colorado, Idaho, Indiana, Kentucky, Missouri, Montana, Nebraska, New Hampshire, New Jersey, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Utah, Virginia, West Virginia, and Wyoming.

Enrolling in Medicare Supplement Plan F is easy and if you also need to sign up for a Medicare Part D plan for the prescription drug plan, it offers many that rate 4 stars or higher on the Medicare Five-Star Rating System.  To enroll, you must reach out to a representative by phone. Its rate for Plan F was the lowest we found, starting at $142 per month for a 66-year-old man. Rates may vary based on age, preexisting medical conditions, and where you live.

Although you cannot enroll in Plan F online, Aetna's website and its Aetna HealthSM mobile app are primed with useful information. While companies rarely list their rates online, Aetna does. Select Your State on the home page and open View Medicare Supplement State Insurance Plans. On the next page, again Select Your State and open the Review Outline of Coverage PDF that appears. This document lists detailed information for all of its Medicare Supplement Plans based on age, gender, and ZIP code. Rates are based on an attained-age model, so your pricing increases as you get older.

Aetna has a 24/7 Medicare Nurse Line to address your health questions. The company also stands out for its generous household discount programs. In many states, you can save up to 7% on your monthly premiums if you live with someone who is also enrolled in one of its Medicare Supplement Plans. The discount rate increases to 14% in 15 states—Arkansas, Arizona, Georgia, Iowa, Illinois, Indiana, Michigan, Mississippi, North Carolina, Nebraska, New Jersey, Oklahoma, Pennsylvania, South Carolina, and Tennessee—if you purchase your plan through the Accendo Insurance Company. Since Original Medicare does not cover them, you may also be interested in enrolling in dental, hearing, and vision coverage.

Best for Discounts: Blue Cross Blue Shield

Blue Cross Blue Shield

Blue Cross Blue Shield

  • Household discounts (up to 7%)

  • New to Medicare Discount ($300 off in your first year)

Not only does it offer Plan F, but it also offers dental, hearing, and vision coverage, in addition to 4- to 5-Star Medicare Part D prescription drug plans that can maximize your coverage options under Original Medicare. Like most companies, its pricing for Medigap is based on an attained-age model in which rates increase based on your age. BCBS rates are competitive, starting at $172 per month for a 66-year-old male in Lansing, Michigan. Rates could change based on age, chronic conditions, or location.

BCBS members have access to a 24/7 nursing hotline. Depending on your state, a wide variety of discount programs are also available. Blue California, for one, offers a New to Medicare discount ($25 per month your first year), a household discount when two or more enrollees live together (7%), an automatic bank payment discount ($3 per month), and discounts for enrolling in a dental plan at the same time ($3 per month).

Best for High-Deductible Plan F: Mutual of Omaha

Mutual of Omaha

Mutual of Omaha

  • High-Deductible Plan F in most states

  • Household discounts (up to 12%)

  • Also offers dental and Part D plans

  • Limited information on the website regarding plans and pricing

  • Rates increase based on age

Founded in 1909, Mutual of Omaha offers a wide range of products from accident and life insurance to financial planning. As one of the first carriers to service Medicare in 1966, it has also built a solid reputation for high-quality Medicare products, offering Plan F in all 47 states where traditional Medicare Supplement Plans are available. If you are looking for High-Deductible Plan F, this company offers it in the majority of states with the exception of Georgia, Hawaii, Maine, Mississippi, New Mexico, New York, Ohio, Tennessee, Texas, Virginia, Wyoming.

With options for Medicare Part D plans and dental insurance, you may find it convenient to have all your healthcare needs met by a single company. Although the Mutual of Omaha website addresses its Medicare Advantage and Medicare Part D options, it provides limited information about Medicare Plan F. Reach out to an agent by phone for quote details, or complete an online form with your name, age, address, and phone number to have one of the company's representatives contact you. Keep in mind that its Medigap plans use attained-age pricing in the majority of states. As you get older, your rates will increase.

The company offers one of the highest household discount rates in the country. With a 12% savings on your monthly premiums, its discount is unique in that it does not require other people to be enrolled in Mutual of Omaha plans. It simply requires you to live with a spouse or someone 60 years or older.

How to Shop and Compare the Best Medicare Supplement Plan F

Step 1: Choose Original Medicare or a Medicare Advantage Plan

Decide what kind of Medicare best suits your needs, Original Medicare (Part A and Part B) or Medicare Advantage (Part C). You can do this when you sign up for Medicare or during the Medicare Open Enrollment (October 15–December 7). You are not eligible for a Medicare Supplement plan when you enroll in Medicare Advantage.

Step 2: Find Out If You Are Eligible for Medicare Supplement Plan F

These plans are not offered to new Medicare beneficiaries in 2020. If you were eligible for Medicare based on a qualifying disability and/or your 65th birthday was before January 1, 2020, you may be eligible for Plan F.

Step 3: Decide Between a Regular Plan F and High-Deductible Plan F

Choose the plan that makes the most sense for you financially. Regular Plan F will offer higher monthly premiums but will begin to pay toward out-of-pocket costs right away. High-Deductible Plan F, on the other hand, offers lower monthly premiums but requires you to pay an annual deductible, set at $2,340 for 2020, before it will pay toward out-of-pocket costs.

Step 4: Find an Available Medicare Supplement Plan F in Your State

Medicare makes this easy by virtue of its Medigap Find a Plan database. Enter your ZIP code for a list of available plans in your area and select View Policies on the right of the screen for a list of companies offering Plan F or High-Deductible Plan F. To narrow the pricing window, there is an option to enter age, gender, and tobacco use on the Main Search page.

Step 5: Get Help From a Medicare Specialist

Medigap plans are nuanced when it comes to pricing. For example, not everyone understands that there is only one Medigap Enrollment Period in your lifetime, not an annual one like there is for other Medicare plans. Signing up late can cause your rates to go up based on preexisting conditions. Your local State Health Insurance Assistance Program or State Insurance Department can help you with issues like this. You can also ask your broker for details.

Step 6: Sign Up for Medicare Supplement Plan F

You may receive marketing mail about Medicare Supplement Plans, especially during Medicare Open Enrollment. The Medigap Find a Plan site on also gives phone numbers and direct website links for each Medigap plan in your state. Reach out to the insurance company of your choice for a quote. In fact, considering reaching out to multiple companies to get the best rate. There is no option to sign up through the Medicare site directly.


Am I Still Eligible for Medicare Supplement Plan F?

Congress passed the Medicare Access and CHIP Reauthorization Act (MACRA) in 2015. One part of the law aimed to reduce access to Medicare Supplement Plans that covered the Part B deductible. Those plans, Plan C and Plan F, are no longer available to new beneficiaries, but you can still sign up for them if you were eligible for Medicare and born before January 1, 2020.

What Is the Difference Between Medicare Supplement Plans F and G?

Medicare Supplement Plans F and G are very similar. The one difference is that Plan G does not cover the Part B deductible ($198 in 2020). Otherwise, they each pay toward the following:

  • 80% of foreign travel expenses (up to plan limits)
  • 100% of blood products (the first 3 pints)
  • 100% of Part A coinsurance and hospital costs up to 365 days
  • 100% of Part A deductible
  • 100% of Part A hospice care coinsurance/copayments
  • 100% of Part B coinsurance/copayments
  • 100% of Part B excess charge
  • 100% of skilled nursing facility coinsurance

Does Medicare Plan F Cover My Prescriptions?

Before Medicare Part D took effect in 2006, certain Medicare Supplement Plans (Plans H, I, and J) offered prescription drug coverage. After January 1, 2006, however, companies were no longer allowed to sell these plans to new beneficiaries. People who had been on them previously were allowed to keep their plans as long as they did not sign up for Part D coverage.

That does not mean that people cannot get prescription drug coverage with the Medigap plans available today. Medicare Supplement Plan F (and all plans that cover Part B coinsurance/copayments) pays toward prescription medications that are covered under Medicare Part B. Any medications under Medicare Part D, however, will not be covered.

How Much Should I Expect to Pay for Medicare Plan F?

The following summary reviews Plan F costs across four regions of the United States. Based on cost summaries from Medicare’s Medigap Find a Plan database, Part F ranges from $106 to $550 per month in 2020.

  • East Coast (Albany, New York): $242–$469
  • Midwest (Lansing, Michigan): $120–$550
  • South (Austin, Texas): $106–$458
  • West Coast (Sacramento, California): $131–$382

Keep in mind this is only a sampling of data. Costs could be higher or lower where you live, depending on your age, your gender, and when you first sign up for Medigap.

How We Chose the Best Medicare Supplement Plan F Companies

Every Supplement Plan F covers the same items, but not every plan is on equal footing. You also need to consider a company’s reputation, pricing structure, website friendliness, and other perks. To find the top Medicare Supplement carriers, we reviewed all companies in the Medigap Find a Plan database that offered Plan F and High-Deductible Plan F. Only those that serviced 40 or more states were considered. Each company was ranked based on the quality and ease of use of its website, price transparency, whether prices were based on age, and the types of plan available (regular vs. high-deductible). Any discounts or perks offered by these companies were also highlighted. For pricing comparisons, we called each company to request a quote for a healthy non-smoking 66-year-old male living in Lansing, Michigan.
