The ONC data update for the April 7, 2015 Federal Advisory Committee on Health IT examines Medicaid eligible professionals' (EP) progress towards meaningful use (MU). The update examines registration, AIU, and attestation rates for the Medicaid EHR Incentive Program. Overall, though more EPs registered with the Medicaid program than expected, Medicaid EPs' progress to MU is slower than Medicare EPs, and fewer than 1 in 10 EPs scheduled for stage 2 in 2014 were registered with the Medicaid program. .
