NOTES: 1. Data represent updated reports; October data are preliminary and are not shown (see Appendix Table 2). Medicaid & CHIP enrollment reports are submitted monthly by state Medicaid agencies, reflecting enrollment on the last day of the month. With each update, states often revise data for the previous month(s) to better align with reporting criteria. 2. Data for Alabama enrollment were recently updated and are expected to be revised in the next data release; the update appears to have had a small impact on the state’s enrollment totals across all months. 3. MO and OK recently approved a Medicaid expansion ballot measure and requires expansion coverage to begin no later than July 1, 2021 in both states.
