More than 6 in 10 uninsured children qualify for Medicaid or the State Childrens Health Insurance Program (SCHIP) but are not enrolled. Reaching these children may not be easy. Medicaid and SCHIP already cover 79 percent of their target populationmore than any other traditional, means-tested program. Moving significantly beyond current participation may require non-traditional strategies. For example, Medicare now uses government data to identify eligible, low-income seniors and provide them with subsidies for prescription drugs and other benefits. SCHIP reauthorization could give Medicaid and SCHIP the flexibility to use similar methods for enrolling eligible, low-income children.
