Medicare is a health insurance program for people 65 and older, people under age 65 with certain disabilities, and people of all ages with End-Stage Renal Disease (permanent kidney failure requiring dialysis or a kidney transplant). Medicaid and the Children's Health Insurance Program (CHIP) provides health coverage to over 72.5 million Americans, including children, pregnant women, parents, seniors and individuals with disabilities. Medicaid is the single largest source of health coverage in the United States. Low income families, qualified pregnant women and children, and individuals receiving Supplemental Security Income (SSI) are examples of mandatory eligibility groups (PDF 177.87 KB). States have additional options for coverage and may choose to cover other groups, such as individuals receiving home and community based services and children in foster care who are not otherwise eligible.
