What Are Medicare Supplement Plans?
Key Takeaways
Medicare Supplement plans, also known as Medigap, allow you to receive private health insurance benefits outside of Medicare and Medicaid plans.
There are 10 supplemental insurance plans to choose from. Supplement plans work alongside Original Medicare, not in place of it.
Medicare Supplement plans are designed to reduce your out-of-pocket expenses and keep your health care coverage affordable.
Medicare supplemental insurance costs vary and depend on factors like location, plan rating, and the insurance company the plan is offered through.
What are the Basic Benefits of Medicare Supplemental Insurance Plans?
You can choose from a number of Medicare Supplement plans, and each plan is required to offer certain standardized, basic benefits. These standardized, basic benefits remain the same no matter the insurance company.
Standardized, basic benefits that must be covered to an extent include:
Supplemental insurance plans also open up the opportunity for sicker patients to have a larger amount of their medical expenses covered. Unexpected and regular out-of-pocket expenses can add up quickly. Having supplemental insurance offers a safety net to help keep these expenses from becoming lifelong, major debt.
What Types of Medicare Supplement Plans are Available?
Insurance companies offering Medicare Supplement plans aren’t required to offer every type of Medigap plan.
Medicare Supplement Plan A
Not to be mistaken with Medicare Part A, Medicare Plan A covers fewer out-of-pocket expenses than any other supplement plan. Medicare Part A only covers the required basic benefits listed previously.
What coverage does Medicare Plan A offer?
Standardized, basic benefits
Medicare Supplement Plan B
Medicare Part A does not cover:
Any other out-of-pocket expenses
Medicare Supplement Plan B
Not to be mistaken with Medicare Part B, this plan covers the same costs as Plan A, as well as hospital deductibles associated with Medicare Part A.
What coverage does Medicare Plan B offer?
Standardized, basic benefits
Part A hospital deductibles
Medicare Plan B does not cover:
Excess charges (charges higher than the amount Medicare approves for specific services)
Coinsurance or copay for skilled nursing care
Medicare Supplement Plan C
Unless you were eligible for Medicare on or before January 1, 2020, you won’t be able to get Plan F.
Plan C covers the majority of expenses not covered by Original Medicare, and it is among the more popular of plans. Note that Plan C is not the same as Medicare Part C.
Looking for Medicare Supplement plans in 2020? Unfortunately, Plan C is one of the two plans that will be going away for new enrollees in 2020. If you are already enrolled in Plan C, you will not be kicked off your plan. If you were eligible for Medicare Part A before 2020, you will also still have the option to enroll in Plan C later.
What coverage does Medicare Plan C offer?
Standardized, basic benefits
Part A hospital deductions
Part B services including coinsurance up to a certain percent, and copays associated with visits to the doctor
Medicare Part B deductibles up to a set amount
Out-of-country travel emergencies within a set limit
Copays or coinsurance for skilled nursing facilities or hospice
Medicare Plan C does not cover:
Excess charges
Medicare Supplement Plan D
Plan D covers the majority of what Medicare doesn’t, except Part B excess charges and the Part B deductible. Medicare Plan D can best be compared to other benefit-heavy plans, such as Plans D, F and G. Plan D should not be confused with Medicare Part D.

Medicare Supplement Plan F
Plan F is the most popular plan because it covers all of the costs Medicare does not. Starting in 2020, Plan F, like Plan C, will no longer be available to new beneficiaries.
If you are already enrolled in Plan F, you will not be kicked off your plan. Also, if you were eligible for Medicare Part A before 2020, you will still have the option to enroll in Plan F later.
