This Center for Medicaid & CHIP Services (CMCS) Informational Bulletin (CIB) lists the end dates of certain COVID-19-related Medicaid and CHIP coverage and enhanced federal funding if the COVID-19 Public Health Emergency (PHE) ends on May 11, 2023, as expected. As part of their response to the COVID-19 PHE, states adopted many temporary flexibilities to support providers and individuals enrolled in Medicaid and CHIP, such as coverage of COVID-19 testing, treatment, and vaccinations. The bulletin provides key dates to assist states with returning to routine Medicaid and CHIP operations. About a quarter of rural adults under age 65 are covered by Medicaid.
