Government entitlement program for the poor who are blind, aged, disabled or members of families with dependent children (AFDC). Each state has its own standards for qualification. A Federally aided, state-operated and administered program which provides medical benefits for certain indigent or low-income persons in need of health and medical care. The program, authorized by Title XIX of the Social Security Act, is basically for the poor. It does not cover all of the poor, however, but only persons who meet specified eligibility criteria. Subject to broad Federal guidelines, states determine the benefits covered, program eligibility, rates of payment for providers, and methods of administering the program. All states but Arizona have Medicaid programs.
