Yes. Medicare helps pay hospital and doctor bills of disabled or retired people who have worked long enough under Social Security to be insured for Social Security benefits. It generally covers people who are 65 and over, people who have been determined to be disabled and have been receiving benefits for at least 24 months, and people who need long-term dialysis treatment for chronic kidney disease or require a kidney transplant. In general, Medicare pays 80 percent of reasonable charges. In most states and in Arkansas, individuals who qualify for SSI disability payments also qualify for Medicaid. The program covers all of the approved charges of the Medicaid patient. Medicaid is financed by federal and state matching funds, but eligibility rules may vary from state to state.
