Which government insurance program is designed for patients aged 65 or older?

The correct choice, Medicare, is a federal health insurance program specifically designed for individuals aged 65 and older. It plays a crucial role in providing coverage for a wide range of healthcare services, including hospital stays, outpatient care, and prescription drug coverage. This program is essential for senior citizens as it helps to manage their medical expenses and ensures they have access to necessary healthcare services.

In contrast, Medicaid is a program that offers health coverage primarily to low-income individuals and families, regardless of their age. TRICARE is a health care program for military service members, retirees, and their dependents, while CHAMPVA provides healthcare coverage for the spouses and children of veterans who are permanently and totally disabled due to a service-related condition. Each of these programs serves different populations and has distinct eligibility criteria, but Medicare's specific focus on those aged 65 and older sets it apart as the correct answer for this question.
