What Do the Letters Mean in Medicare Supplement Plan Names?

Last Updated : 09/16/20183 min read

If you’ve just started researching Medicare Supplement plans, you may have noticed that each plan is labeled with a different letter. Here’s a quick overview of what those letters mean, the differences between the Medicare Supplement plan types, and how to find a plan that may work for your needs.

What are the different Medicare Supplement plans?

Medicare Supplement (Medigap) plans help cover certain out-of-pocket costs that Original Medicare doesn’t cover, like copayments, coinsurance and deductibles.

There are 10 plans available in most states, and the letter of the plan (for example, “Medicare Supplement Plan F”) helps you identify which benefits go with it.

Benefits are standardized across each plan letter. So, this means that if you’re interested in Medicare Supplement Plan B, for example, the minimum coverage will be the same across every Medigap Plan B offered in your service area, no matter which insurance company you buy from. This means that once you’ve narrowed down which Medicare Supplement plan has the benefits you want, you can focus on comparing factors that may vary, such as premium cost, since minimum coverage will be the same across each letter type.

Most states offer the following 10 Medicare Supplement plan types:

  • Plan A
  • Plan B
  • Plan C
  • Plan D
  • Plan F (also comes with a high-deductible version)
  • Plan G
  • Plan K
  • Plan L
  • Plan M
  • Plan N

A few other things to note:

  • Massachusetts, Minnesota, and Wisconsin standardize their Medicare Supplement plans differently.
  • Insurance companies don’t have to sell every Medicare Supplement plan.
  • Any insurance company that sells Medicare Supplement coverage must offer Medigap Plan A.
  • Insurance companies that offer more than one plan must also sell Medicare Supplement Plan C or Plan F.

How can I find a Medicare Supplement plan?

Every person’s situation is different. You might find it useful to speak with a licensed insurance agent who can go over the differences between the different types of Medicare Supplement plans and help you find a plan that may work for your needs, preferences, and budget.

Remember, because Medicare Supplement plan benefits are standardized across plans of the same letter name, the main difference between plans of the same type will be price. So, it’s in your best interest to take the time to research plan options and compare the different choices in your specific zip code.
