Organizations that help families obtain health insurance for their children under the State Children's Health Insurance Program (SCHIP), a program that is jointly financed by the federal and state governments and administered by the states. In some states, CHIP is an expansion of the Medicaid program and allows children of parents with higher incomes than were allowable in the past to participate and receive health insurance through Medicaid. In other states, CHIP is a separate program from Medicaid and covers children whose parents have incomes that are higher than the state's Medicaid eligibility levels. Within broad Federal guidelines, each state determines the design of its program, eligibility groups, benefit packages, payment levels for coverage, and administrative and operating procedures. The insurance pays for doctor visits, immunizations, hospitalizations and emergency room visits, but additional services may be available depending on the benefits defined by the state. Depending on the family's income, insurance premiums and co-pays may apply.
