Which of the following is TRUE about Medicare?

Medicare is primarily designed to serve individuals aged 65 or older, which makes this response accurate. While certain individuals under age 65 may also qualify for Medicare due to disabilities or specific medical conditions, the primary purpose and structure of Medicare are aimed at providing health care coverage for seniors. This is due to the fact that many older adults face health challenges that necessitate access to medical services, making Medicare an essential program for this age group.

The other options do not accurately represent Medicare's characteristics or eligibility requirements. Medicare is not available to individuals of any age as a standard rule, its coverage extends beyond just hospital stays to include outpatient services and preventive care, and while it used to be that Original Medicare did not cover most outpatient prescription drugs, Medicare now offers a separate Part D plan specifically for drug coverage.
