Medicare provides coverage primarily to which age group?

Medicare is a federal health insurance program that primarily serves individuals who are 65 years of age and older. This specific age threshold is established by federal law and is a critical aspect of the program's design. While Medicare does provide services to younger individuals with disabilities or specific health conditions, the core demographic that the program is intended for is those who have reached retirement age. Therefore, option B accurately reflects the primary target population of Medicare coverage, which is primarily individuals aged 65 and older. Understanding this distinction is essential for anyone studying the revenue cycle and interacting with insurance claims processes related to Medicare.
