Medigap Coverage: How To Know What’s Right For You

What is Medigap?

Medicare Supplement Insurance Plans (Medigap) coverage refers to plans that help to fill any gaps in Original Medicare (Medicare Part A and Medicare Part B) coverage. Medigap plans are purchased in addition to Original Medicare, not to replace Original Medicare. Medigap does not work with Medicare Advantage (Medicare Part C). Medigap pays part or all certain remaining costs after Original Medicare pays first. The Medigap policy covers coinsurance after the individual pays the deductible. Some Medigap policies pay the deductible.

Every Medigap policy must follow federal and state laws designed to protect the consumer. Medigap policies are required to be identified as “Medicare Supplemental Insurance”. All policies offer the same basic benefits, but some offer additional benefits. In Massachusetts, Minnesota, and Wisconsin, Medigap policies are standardized differently

How does Medigap work?

Private companies sell Medigap to fill in coverage gaps in Original Medicare. Medicare Part B pays around 80% for some covered services. The individual is responsible for the remaining 20%. A Medigap plan can pay the remaining 20%. Medicare Part A has a large per-event deductible and full coverage lasts only 60 days. A Medigap plan can pay the deductibles and coinsurance so an inpatient stay will cost little to nothing out-of-pocket. Medigap policies may cover health care costs that Medicare does not like care received when traveling.

Who is eligible for Medigap coverage?

An individual must be enrolled in Original Medicare (Medicare Part A and Medicare Part B) to be eligible for a Medigap policy. Individuals with a Medicare Advantage Plan (Medicare Part C) are not eligible for a Medigap policy.
