Medigap

Medicare Supplement Insurance (Medigap) is extra insurance you can buy from a private insurance company to help pay your share of costs in Original Medicare. You can only buy Medigap if you have Original Medicare. Generally, that means you have to sign up for Medicare Part A (Hospital Insurance) and Part B (Medical Insurance) before you can buy a Medigap policy.

All Medigap policies are standardized. This means, they offer the same basic benefits no matter where you live or which insurance company you buy the policy from. There are 10 different types of Medigap plans offered in most states, which are named by letters: A-D, F, G, and K-N. Price is the only difference between plans with the same letter that are sold by different insurance companies.
