(4) In reporting on all Child and Adult Core Set measures, the agency is required to report on all Medicaid and CHIP beneficiaries, including those enrolled in fee-for-service and managed care, unless—

(6)(i) The agency may request a 1-year exemption from reporting for a specific population defined by the State for one or more Child and/or Adult Core Set measures if the agency demonstrates that it:
