This tutorial gives a broad overview of Medicaid and CHIP, the many different populations these programs serve, the changes they are undergoing under health reform, and some detail to help readers think about opportunities to improve access to coverage for CSHCN through communication and collaboration with Medicaid and CHIP staff. The tutorial starts with an overview of how definitions of CSHCN may vary by agency or program, followed by eight major topic areas and then recommendations for steps Title V programs can take to build successful partnerships with public insurance programs.
