What it means

Medigap, also called Medicare Supplement Insurance, is private insurance sold by insurance companies to help pay the gaps in Original Medicare—copays, coinsurance, and deductibles you would otherwise pay out of pocket. Medigap policies are standardized by the federal government and labeled with letters (A, B, D, G, K, L, M, N), meaning each lettered plan type offers identical core benefits regardless of the company selling it. Medigap does not cover prescription drugs—you need a separate Medicare Part D plan. Medigap is designed for beneficiaries on Original Medicare and does not work alongside Medicare Advantage plans. Premiums vary by insurer and location even for the same plan letter.
