We recommend that the State agency ensure that CalHEERS and SAWS have the system functionality to: deny or discontinue Medicaid for an ineligible beneficiary after a previous determination has already been made on the basis of the beneficiary’s MAGI, properly process cases for beneficiaries who were formerly in the foster-care youth program, use SSA data to verify whether a beneficiary is entitled to or enrolled in Medicare, properly redetermine eligibility when a beneficiary is no longer a child, and retrieve and use information from the Department of Homeland Security to determine whether a beneficiary has met the 5-year-bar requirement to be eligible to receive full-scope Medicaid services.
