Medicare benefits primarily serve individuals who are aged 65 years and older, as this age group has historically been the focus of the program since its inception in 1965.

Even though there are provisions for younger individuals with certain disabilities or specific health conditions, the cornerstone of Medicare is its coverage for individuals aged 65 and over.

This emphasis on age is critical for understanding how Medicare was structured to address the unique healthcare needs of the elderly population, ensuring they have access to necessary medical services, preventive care, and hospitalizations without the burden of excessive out-of-pocket expenses.
