Where can we find guidance on how CMS implemented the MBI initiative for RAPS and EDS?

CMS issued Medicare Beneficiary Identifier (MBI) Implementation Guidance on December 22, 2017. Please refer to the December 22, 2017 CMS Health Plan Management System (HPMS) memo, “Updates to the Encounter Data System and Risk Adjustment Suite of Systems to Accommodate the New Medicare Card Project” for guidance on how these systems implemented the MBI initiative. In addition, CMS released two additional HPMS memos on MBI implementation, the December 10, 2018 HPMS memo titled, “Updates to the Risk Adjustment Suite of Systems (RASS) for Delete Transactions using a Beneficiary Identifier” and the September 6, 2019 HPMS memo titled, “Risk Adjustment Suite of Systems (RASS) MBI Related Enhancements.”
