The COVID-19 Public Health Emergency (PHE) continues to play a significant role in Medicaid/CHIP enrollment, which is why CMS continues to develop tools and strategies to support operations and enrollees in times of crisis, including granting states additional temporary flexibilities in their Medicaid and CHIP operations.

[1] Over 11 million individuals are dually eligible for Medicare and Medicaid, so are counted in the enrollment figures for both programs. As a result, adding the enrollment figures for the programs means these individuals are counted twice. The total of 135 million only counts dually eligible individuals once.

[2] Enrollment data for Medicare and Medicaid/CHIP are compiled on different timelines owing to the unique nature of each program. There is typically a delay in publishing Medicaid and CHIP enrollment data due to states accounting for retroactive enrollment and data lags.
