During the 1990s and early 2000s many states expanded Medicaid eligibility for parents particularly after the 1996 welfare reform. At the same time, welfare reform also put in place policies that limited the eligibility of recent immigrants for public programs including Medicaid. This paper evaluates the effects of these changes in Medicaid eligibility policy on the private and public health insurance coverage of immigrants as well as the overall insurance rate. It also looks at the effect on health care use and measures of health status. The findings indicate a significant increase in Medicaid coverage and an increase in the proportion insured overall with negligible crowd-out of private insurance. There is also an increase in the use of health care services. In the case of permanent residents, there is a diminished response to Medicaid eligibility changes possibly due to a “chilling effect”.
