11.6 Medicare Supplement Insurance (Medigap) Overview
Purpose
Medicare Supplement (Medigap) policies are private insurance plans designed to supplement Original Medicare by covering certain out-of-pocket costs. These plans may pay all or part of deductibles, copayments, and coinsurance, and some may also provide coverage for services not included under Medicare.
To purchase a Medigap policy, an individual must generally be enrolled in Medicare Parts A and B. Medigap requires a separate premium, and coverage is guaranteed renewable, meaning the policy remains in force as long as premiums are paid. Each Medigap policy covers one individual only.
Medigap policies are standardized and regulated by federal and state laws. Each policy must clearly be labeled as “Medicare Supplement Insurance.” While all standardized plans provide the same core benefits, premiums may vary depending on the insurer.
Open Enrollment
Individuals age 65 or older may purchase a Medicare Supplement (Medigap) policy by paying the required premium. The Medigap Open Enrollment Period lasts for 6 months, beginning in the month the individual turns 65 and is enrolled in Medicare Part B.
During this period, insurers are prohibited from using medical underwriting, denying coverage, charging higher premiums based on health status, or imposing waiting periods for pre-existing conditions.
