Congress passed an FY 2023 spending bill that disentangled the Medicaid coverage protections from the the COVID-19 public health emergency (PHE). This law required states to begin processing Medicaid redeterminations by March 31, 2023. Redetermination is the process by which state Medicaid offices determine the eligibility of continuing Medicaid health care coverage for current enrollees. States that have expanded Medicaid allow Medicaid eligibility due to low income. States that have not expanded Medicaid require proof of low income AND another individual characteristic such as age, disability, and illness. This fact sheet describes how supportive housing programs should prepare for Medicaid redeterminations, by March 31, 2023 in all 50 states.
