Medicare Supplement Insurance (Medigap) Explained
by Christian Worstell | Published April 26, 2021 | Reviewed by John Krahnert
Medicare Supplement Insurance is private insurance that can help cover some of the out-of-pocket costs that Original Medicare (Part A and Part B) does not, such as copayments, coinsurance and deductibles. Comparing Medicare Supplement Insurance plans can help you find the right policy for your health care needs.
Medigap Plans Help Cover Some Out-of-Pocket Costs
There are 10 Medigap plan types available in most states. Medicare Supplement Insurance plans are sold by private insurance companies, but their basic benefits are standardized by Medicare. These plans are labeled Plan A, B, C, D, F, G, K, L, M and N, and each plan covers a different set of basic benefits.
Important: Plan F and Plan C are not available to beneficiaries who became eligible for Medicare on or after January 1, 2020.
In order to purchase one of these Medigap plans, you must already be enrolled in Medicare Part A and Part B, and you can only purchase a plan from an insurer in your state that is licensed to sell them. A Medicare Supplement Insurance plan will cost you a monthly premium in addition to your Medicare Part B monthly premium. Premium costs vary depending on the insurer.
|
Note: Medigap policies are standardized differently in Massachusetts, Minnesota and Wisconsin. |
Not every insurer offers each type of Medigap plan. However, if an insurance company sells any Medigap policy, they must offer at least Medigap Plan A and either Medigap Plan C or Plan F. Medicare Supplement Insurance plans only cover one person, so if you and your spouse are both eligible, you’ll each need to purchase a separate policy.
|
Note: You cannot purchase a Medigap plan if you have a Medicare Advantage plan. If you want to disenroll in your Medicare Advantage, you must make sure you can leave your plan before enrolling in Original Medicare and purchasing a Medigap plan. |

Medigap Plan F is the most comprehensive type of plan, which explains why it's also the most popular type of Medicare Supplement Insurance plan. You may be better served with a less comprehensive plan, however, so it's important to compare each type of basic benefit.
