Names of Medicaid and CHIP Programs
State-specific names for Medicaid and CHIP programs (as of September 2023) can be found at HealthCare.gov – Medicaid and CHIP program names in your state.
The share of Medicaid/CHIP enrollees in the child, adult, disability, and senior eligibility groups calculated from MACStats: Medicaid and CHIP Data Book, Exhibit 14. Medicaid Enrollment by State, Eligibility Group, and Dually Eligible Status (Medicaid and CHIP Payment and Access Commission (MACPAC): December 2022). The “New Adult” and “Other Adult” groups are combined for the total “Adult” share shown.
The number of children in each state covered by Medicaid/CHIP estimated from Georgetown Center for Children and Families (CCF) analysis of Centers for Medicare & Medicaid Services (CMS) State Medicaid and CHIP Applications, Eligibility Determinations, and Enrollment Data for January 2023, available at data.Medicaid.gov. All states and the District of Columbia are required to report monthly Medicaid and CHIP enrollment data to CMS as part of the Performance Indicator Project. CCF uses updated, rather than preliminary, enrollment data whenever possible. CCF substitutes state administrative data in Arizona because the state does not report child enrollment to CMS; CCF also substitutes state administrative data for Indiana due to recent adjustments to the state’s CMS reporting methodology.
The share of foster children in each state covered by Medicaid/CHIP found in “Health-Care Coverage for Children and Youth in Foster Care—and After” (Child Welfare Information Gateway: 2022), available at https://www.childwelfare.gov/pubs/issue-briefs/health-care-foster/.
The share of children with disabilities or special health care needs in each state covered by Medicaid/CHIP found in Appendix Table 1 of “Children with Special Health Care Needs: Coverage, Affordability, and HCBS Access” (Kaiser Family Foundation: October 2021), available at https://www.kff.org/report-section/children-with-special-health-care-needs-coverage-affordability-and-hcbs-access-appendix/.
The share of infants, toddlers, and preschoolers in each state covered by Medicaid/CHIP estimated from CCF analysis of the U.S. Census Bureau 2021 American Community Survey (ACS) Public Use Microdata Sample (PUMS). Infants, toddlers, and preschoolers are defined as children under 6 years of age (children ages 0-5).
