Which of the following is a basic benefit of Medicare Supplemental Insurance?

While some Medigap plans may offer benefits related to at-home care, this is not a standardized benefit of Medicare Supplemental Insurance. Typically, at-home recovery services are considered home health care and may fall under different Medicare provisions rather than being a direct benefit of Medigap policies.

Medicare Supplemental Insurance does not provide coverage for prescription drugs, thus there is no "basic drugs limit" associated with it. While some plans may offer limited drug coverage, Medigap is primarily designed to cover gaps in Original Medicare rather than managing prescription medications, which are typically covered under separate Medicare Part D plans.

Preventive care is generally covered under Original Medicare without the need for Medigap insurance. Services such as screenings and vaccinations are provided by Medicare, making this option unrelated to the specific benefits offered by Medicare Supplemental Insurance policies.
