Encounter Data Processing System Maintenance
Starting October 10, 2022, the Encounter Data Processing System (EDPS) will begin maintenance activities that will last for approximately four (4) days. During the maintenance period CMS’s Encounter Data Front End System (EDFES) will continue to accept and process submitted encounter data and transmit TA1, 277CA and 999 reports to submitters. However, the back end, EDPS will hold the encounter data files in a pending status.
As a result, encounter data transaction reports generated by the EDPS (MAO-001 and MAO-002) will not be produced. CMS anticipates beginning processing of the backlogged reports on October 17, 2022, or as soon as the maintenance is completed. Return of MAO-001 and MAO-002 reports will be on a rolling basis based on first in first out. CMS will notify plans when the backlog is fully processed.
