Final answer:
Medicare supplement policies, also known as Medigap policies, fill the gaps in coverage provided by Medicare and cannot duplicate the benefits already covered by Medicare.
Step-by-step explanation:
Medicare supplement policies, also known as Medigap policies, are designed to fill the gaps in coverage provided by Medicare. However, these policies are not allowed to duplicate the benefits already provided by Medicare. This means that any benefits covered by Medicare cannot be duplicated by a Medicare supplement policy.
For example, if Medicare covers a certain medical procedure or service, a Medicare supplement policy cannot provide additional coverage for the same procedure or service. The purpose of the Medigap policies is to provide additional coverage for expenses not covered by Medicare, such as deductibles, copayments, and coinsurance.
So it's important to understand what benefits are already covered by Medicare before considering a Medicare supplement policy, to avoid paying for duplicate coverage.
