Millions of Americans rely on Medicare and Medicaid for healthcare coverage, yet many people still confuse the two programs. While both are government-backed health insurance systems, they serve different populations, have different eligibility rules, and cover healthcare costs differently.

What Is Medicaid?
Medicaid is a joint federal and state health insurance program designed for people with limited income and resources. Eligibility rules and benefits vary by state.
