Medicare vs Medicaid is one of the most frequently asked healthcare questions in the United States. Although both programs are government-funded health insurance systems, they serve different populations and operate under different eligibility rules. Medicare primarily covers individuals aged 65 and older or those with certain disabilities, while Medicaid supports low-income individuals and families. Understanding the differences between Medicare and Medicaid helps individuals make informed healthcare decisions. This guide explains eligibility requirements, coverage benefits, funding sources, cost structures, and how dual eligibility works in simple international English.
What Is Medicare
Medicare is a federal health insurance program primarily for individuals aged 65 and older. It also covers certain younger individuals with disabilities and those with end-stage renal disease. Medicare is managed at the federal level and has standardized coverage across states.
What Is Medicaid
Medicaid is a joint federal and state health insurance program designed for low-income individuals and families. Eligibility and benefits vary by state because states administer the program within federal guidelines.
