<human>:  How do Medicare and Medicaid differ?
<bot>: Medicare is a program administered by the federal government that provides health insurance benefits to people who are over the age of 65, people with disabilities, and people with end-stage renal disease. Medicaid is a health insurance program funded jointly by the federal government and state governments that provides health coverage to people in specific categories, such as low-income individuals, pregnant women, and persons with disabilities. Medicare is available to all eligible individuals regardless of income or resources, while Medicaid offers certain categories of individuals a greater degree of coverage. Medicare generally covers outpatient services, such as doctor's office visits and preventive care, while Medicaid often pays for both inpatient and outpatient services.
