A combined federal and state program administered by the state that provides medical benefits for individuals and families with limited incomes who fit into an eligibility group that is recognized by federal and state law. Each state sets its own guidelines regarding eligibility and services within parameters established at the federal level. Many people are covered by Medicaid, though within these groups, certain additional requirements must be met. Eligibility factors include people's age, whether they are pregnant, have a disability, are blind, or aged; their income and resources (like bank accounts, real property or other items that can be sold for cash); and whether they are U.S. citizens or lawfully admitted immigrants. Families who are receiving benefits through TANF and individuals who receive SSI as aged, blind and disabled are categorically eligible groups. The rules for counting a person's income and resources vary from state to state and from group to group. There are special rules for those who live in nursing homes, for people served under the Medicaid Waiver program, for people served by Program of All-Inclusive Care for the Elderly (PACE) programs and for children with disabilities living at home. Medicaid makes payments directly to a person's health care provider; and some recipients may be asked to pay a small part of the cost (co-payment) for some medical services. Most states have additional "state-only" programs to provide medical assistance for specified low-income persons who do not qualify for the Medicaid program.
