This study found that children in families where siblings are eligible for different public insurance programs are less likely than other children to be insured, even when all children are eligible for public coverage.  The paper finds that recent policies to encourage enrollment have not improved coverage of this “mixed eligibility” population and further finds that states where the State Children’s Health Insurance Program (SCHIP) is separate from Medicaid have higher mixed eligibility uninsurance rates that states in which SCHIP is part of the Medicaid program.
