Medicare is a great option for seniors. In fact, those 65 and older who qualify for Medicare often cite it as one of the best health plans. However, it doesn’t take care of everything. In fact, you may need extra insurance, known as Medicare Supplement or Medigap, to fully manage your healthcare issues as you age.

Need Help Finding a Medicare Plan?

Find Affordable Healthcare That’s Right for You


If you’re looking for some different options, based on your individual needs, here are some of the best Medicare Supplement companies for 2022.

Largest insurer with high marks in financial strenght and customer satisfaction

Second-largest insurer with coverage in all 50 states

Offers plans with broad coverage at lower premiums

Easy to bundle coverage and save

“Right fit guarantee,” high levels of customer satisfaction

Available in all 50 states, access to discounts and perks

Specializes in insurance products for older Americans

Largest insurer in Massachusetts

Known for a frugal and affordable approach to insurance pricing.

Medicare Supplement insurance, also known as Medigap, augments your basic Medicare coverage by typically paying the 20% cost that Medicare does not cover.

Ten basic Medigap policies exist, each with different benefits. Once you have decided the policy that is right for you, find a company that sells it. This applies to Medicare coverage throughout the country, save for a few states.

In some ways, Medicare Supplement plans are simple: 

  • Unlike Medicare Advantage plans, Medigap plans don’t make any coverage decisions. 
  • You can see any doctor or hospital that accepts Medicare. 
  • Medicare Supplement plans pay the specified share of your medical bills that Medicare doesn’t pay, including deductibles and copays. No questions asked.

While the basic benefits are the same for every Medicare Supplement policy, costs vary widely, and some companies offer additional benefits that might make choosing their plans attractive to you.

The rules concerning enrollment and switching plans are complex. Choose a Medicare Supplement plan with your future in mind because you have the best opportunity to get the right plan when you sign up initially. At that point, how healthy you are doesn’t count. 

Later, if you try to switch Medigap plans, you’ll probably face underwriting — a health exam. That might mean you’ll be rejected or the price will be significantly higher than it would have been initially. 

Who Are the Established Top Medicare Supplement Insurance Carriers?

In some metropolitan areas, more than 20 insurance companies sell Medicare Supplement insurance.1 Consider the following companies for coverage, based on market share:

  • AARP/United Health Group
  • Mutual of Omaha
  • CVS/Aetna
  • Anthem
  • HCSC
  • Cigna
  • CNO Financial (Resource Life Insurance Company)
  • BCBS of Massachusetts
  • Wellmark

What You Need To Know To Choose

  • Consider the monthly premium price. Medicare supplement insurance is highly regulated; insurers must offer essentially the same coverage for each of the 10 types of Medicare supplement policies. Make sure you can handle the monthly expenses and you are comfortable with the value.
  • Calculate the total out-of-pocket costs. Include your monthly premium and an estimate of Part D drug coverage, which Medicare supplement plans don’t include. 
  • Check out incentive benefits. Some insurers offer Medicare supplement customers incentives such as a discount on dental, hearing or vision insurance purchases. They may also have free or discounted gym plans. 
  • Consider these issues. The most popular is Plan F, but it is no longer available to new enrollees. Plan G and Plan G high deductibles are similar, but they don’t cover the Medicare Part B deductible, which Plan F does. They do cover Part B excess charges, which can be an advantage if the healthcare provider you pick charges more than Medicare allows. Another popular feature available in Plan G and some of the other plans is coverage of foreign travel emergencies. 
  • Evaluate customer service. Good customer service is what sets Medicare supplement plans apart. Asking friends and neighbors who subscribe is a way to rate customer service in your area. 

Numerous supplemental plans from which to choose

Ten basic Medigap policies exist, each with different benefits.

Medicare supplement insurance may seem costly, but a recent study showed that 17% of people with Medicare supplement insurance spent more than 10% of their income on medical costs vs. 23% with those who had Medicare Advantage.2

Special benefits: Anthem Blue offers compatible Part D prescription drug plans and access to affordable dental, vision, and hearing plans.17 The best thing about being part of the BCBS network is the similarity of coverage nationwide.

Why Choose a Medicare Supplement Plan?

All of these companies also offer Medicare Advantage plans. Buying Medicare insurance isn’t an easy decision, and understanding the difference between Medigap and Medicare Advantage plans before you choose one or the other is a good idea. 

Medicare Supplement insurance plans work with Original Medicare, Part A, and Part B. They pay costs that Original Medicare doesn’t. 

Medicare Advantage is different. It replaces original Medicare and might be similar to the health insurance you had before you enrolled in Medicare. Because you are no longer in the federal system, the plans have differences. Reading and asking questions about those differences before you sign up is important. 

Cost of supplemental plans vary

While the basic benefits are the same for every Medicare Supplement policy, costs vary widely, and some companies offer additional benefits that might make choosing their plans attractive to you.
