Medicaid helps cover health care costs, such as doctor visits, hospitalization, and medications, for those who meet the eligibility requirements set by the state in which they reside.

Medicare is aimed at seniors and people with disabilities, while Medicaid is aimed at low-income individuals and families. Additionally, the rules and specific coverage can differ significantly between both programs and between different states.
