We evaluated 10 well-known Medicare supplement insurance plans, and after careful review identified the eight best options for 2020. To draw our conclusions, we checked with customers in the market, reviewed data and consulted insurance experts. In summary, no one plan is best for all situations, so we recommend shopping around using a Medicare expert like United Medicare Advisors to compare plans. The eight Medicare supplement insurance companies we think are worth your consideration include: United Medicare Advisors, Cigna, Mutual of Omaha,, Humana, Blue Cross Blue Shield, Aetna and AARP by United Healthcare.

How much do you know about Medicare supplement insurance? Contrary to common belief, Medicare, the government-funded healthcare insurance for American citizens age 65 and up, doesn’t cover 100% of your medical costs. Medicare supplement insurance plans add additional coverage to fill the gap in coverage between Medicare and your actual medical expenses. Private companies sell these so-called “Medigap” policies, which are typically used to cover expenses like deductibles and co-pays.

Coverage can be difficult to understand, and varies by market. Massachusetts, Minnesota, and Wisconsin provide their own policies for residents. The remaining 47 states in the U.S. rely on 11 standard plans that accommodate all types of health, lifestyle, and budget demands. These plans vary based coinsurance needs such as hospital stay, hospice care, travel expectations and more.

In this guide, we’ll provide tips for making a well-informed Medigap insurance purchase, investigate the best companies in the industry, and address some frequently asked questions.

Top tips:

  • Insist on price transparency
  • Enrollment starts when you are 65 or older and enroll in Medicare Part B

Tips For A Wise Buyer

Be sure to sign up for Medicare supplement insurance within the 6-month window after you turn 65 (or elder) AND enroll in Medicare Part B. When asked what the number one biggest mistake Americans make is regarding Medicare supplemental insurance, a spokesman with the U.S. Social Security Administration told us “Everyone thinks they have enough coverage when they’re 65 if they’re working or if they have insurance through their spouse. They don’t think they have to sign up. Then later they find out they have missed their open enrollment period.”

During the open enrollment timeframe, federal law bans insurers from denying you coverage or charging higher premiums if you have a pre-existing health condition or disability. If you try to sign up after that window, you will likely pay more for premiums and may even be denied.

Start planning as soon you turn 65

Understanding the fine print in a supplemental policy makes a big difference. Research will help you avoid situations like being charged extra out-of-pocket or out-of-network fees. Ultimately, coverage options for supplement insurance varies by plan type and provider, so it’s difficult to know what factors are most important.

Consider these three major factors to find the best supplemental insurance policy: price transparency, helpfulness, and coverage.

New for 2019

Sometimes the government changes things like open enrollment periods and what Medicare supplement plans are offered. Here is what’s changed for 2019 according to

  • Plan F will no longer be offered at the end of 2019
  • Plan G is believed to be the new go-to plan if you once had Plan F as it is basically the same except for the deductible.

Price transparency

There are going to be a number of expenses, charges, and premiums to decode. Set your budget first, then look for a company that is upfront about premiums before you sign on the line.


You should be informed before buying. If you’re reading this guide, that’s a good start. And in general you should be a skeptical buyer, although Medigap insurance is heavily regulated. Still, shopping for insurance can be exhausting, but the best companies make the process as streamlined as possible. Look for a company that caters to your needs, such as a physical office for a face-to-face meeting, a helpful customer service representative on the phone, or online chat.


The more coverage choices available, the more opportunities you have to save and get the best care. Look for companies that offer several or all of the 10 standard plans, then pick what works best for you.**

Searching for the right policy can be difficult, so we did it for you. The approach we took to hone in on the top supplemental insurance companies was as follows:

  1. We considered a large number of supplemental insurance companies

    We kicked off our search with 10 Medicare supplement insurance companies that offer a multitude of plans. We included companies that appeared in popular website queries, and those that spent a large amount of money advertising on TV or the radio. These are the companies most likely to be shopped by consumers.

  2. We followed our own buying tips

    Next, we analyzed these companies based on our expert-guided buyer criteria in three categories: price transparency, helpfulness, and coverage. Companies that obscured their prices, made the process very difficult, or had limited coverage options were cut from the search.

  3. We shopped for policies

    We contacted companies and asked for more information. We found out that policies ranged in price from less than $100/month for basic coverage to thousands for maximum protection.

    Then, we shared these best companies for you, a friend or family member to consider.

Frequently Asked Questions about Medicare Supplement Plans

When should I buy Medicare Supplement Insurance?

Put this on your calendar – the Medigap open enrollment period. That’s a six-month window which kicks off the first month you’re 65 and enrolled in Medicare Part B. If you sign up for Medicare supplemental insurance during this period, you can join any plan (even if you have a pre-existing condition).

You can still buy Medicare supplemental insurance after this window but you will pay a price – literally. After this enrollment period, insurers may increase premiums or deny coverage.

Do I have to purchase Medicare supplement insurance?

No. but can you afford not to? 9 out of 10 people have a type of supplemental coverage, according to the AARP.

If you forgo supplemental insurance, then you’re responsible for out-of-pocket health insurance costs – that can quickly cost thousands of dollars. If you’re on a fixed income, this may quickly eat into your retirement savings. Unless you can guarantee that you won’t have more than a sniffle for the rest of your life, coverage is probably a good financial move.

What if I’m 65 or older and still using my employer coverage?

If you are one of millions of Americans working after 65, your employer health insurance coverage may be all you need for now. Medicare supplement open enrollment generally won’t begin for you until you enroll in Medicare Part B. If you haven’t enrolled in Part B yet, you should consider waiting to enroll until you are ready for your Medicare supplement open enrollment to begin.

If you aren’t sure if you are eligible for coverage, start by finding out if you are eligible for Medicare.

How much does Medicare supplemental insurance cost?

We found policies that ranged in price from less than $100/month for basic coverage to thousands for maximum protection. There’s no “normal” number, as there are so many factors in play like where you live, your age and needs. A ballpark figure is a couple hundred dollars a month for standard coverage. However, it’s basic economics – the more supplemental insurance you want, the greater the cost.

Can I get a discount?

Yes. Some plans offer discounts if you’re married (studies show that married couples tend to be healthier – as they encourage each other to eat nutritious meals, exercise, and see a doctor). You can also possibly cut your rate if you’re a non-smoker, as you’ll likely have fewer health risks. Or you may be able to save by paying annually or via electronic funds transfer. Even if the website or brochure you’re studying doesn’t mention anything about discounts – ask.

For more information, find out how premiums are calculated.

Are all 11 Medicare supplemental insurance plans the same in every state?

While there are 11 different plans in most of the U.S., federal law mandates that each plan carry the same coverage. For example, Plan K in New York offers identical benefits to Plan K in New Mexico.

Where else can I turn for more information?

Call your State Health Insurance Assistance Program. Enter your state, and the contact phone number and website of the local office will appear.

Another website site to check out: The U.S. government-run Medicare site. In addition to being the final resource on Medicare and Medigap insurance, the site has a ZIP-based search to find a Medigap policy in your area.


Bottom line:
Medicare supplement insurance coverage is one of the most important health and financial decisions you make for retirement.

If you decide to buy Medicare supplemental insurance, talk with a representative and walk through every cost – and get a list of the cost and benefits in writing. Good companies will offer you this price transparency, and this way you’re not surprised by a large bill or with coverage you don’t need.

Buying a policy can be complicated, so get help and find a helpful policy provider. There are many coverage choices available, and the right plan may help you significantly reduce unwanted medical costs. Before you sign up, it’s a good idea to have a friend or family member review your policy. If that’s not an option, we found the following companies were the best and therefore should be a good choice.
