Which government program provides health insurance primarily for individuals aged 65 and older?

Medicare is the government program specifically designed to provide health insurance primarily for individuals aged 65 and older. It was established to ensure that older adults have access to necessary healthcare services, including hospital care, outpatient services, and various forms of medical treatment. The program plays a crucial role in the United States' healthcare system, allowing elderly individuals to manage their health costs more effectively.

Understanding Medicare's structure is important: it includes various parts that cover different aspects of healthcare. For example, Part A covers hospital insurance, while Part B covers medical insurance. There are also additional options like Part C (Medicare Advantage) and Part D (prescription drug coverage) that enhance the basic offerings.

While other programs like Medicaid provide healthcare coverage, they primarily serve low-income individuals and families, regardless of age. The Children's Health Insurance Program (CHIP) focuses on providing coverage to children in families with incomes too high to qualify for Medicaid but too low to afford private coverage. Veterans Affairs offers services and benefits specifically to veterans of the military, which is separate from the services offered by Medicare. Thus, the designation of Medicare for individuals aged 65 and older is clear and distinct, making it the correct answer.
