HL7-defined code system of concepts specifying application response levels defined for a given Master File Message at the MFE segment level, and used for MFN-Master File Notification message. Specifies additional detail (beyond MSH-15 - Accept Acknowledgment Type and MSH-16 - Application Acknowledgment Type) for application-level acknowledgment paradigms for Master Files transactions. Used in HL7 Version 2.x messaging in the MFI segment.
