What does Medicare primarily provide for?

Medicare primarily provides healthcare coverage for individuals aged 65 and older, as well as specific disabled individuals under the age of 65. This program is a federal health insurance initiative that serves the needs of seniors and certain younger individuals who qualify due to disabilities, ensuring that they have access to essential medical services.

This approach is crucial as it recognizes the unique healthcare needs of aging populations and those with disabilities, providing them with necessary medical, hospital, and preventive care. By focusing on these groups, Medicare aims to support their health and financial security, reducing barriers to accessing healthcare.

The other options do not accurately describe Medicare's target demographic or function, which is why they do not align with the correct answer.
