MFI segment

The Technical Steward for the MFI segment is CQ. The fields in the MFI segment are defined in HL7 Attribute Table - MFI. 8.5.1.0 MFI Field Definitions 8.5.1.1 MFI-1 Master File Identifier (CE) 00658 Definition: This field is a CE data type that identifies a standard HL7 master file. This table may be extended by local agreement during implementation to cover site-specific master files (z-master files).

required optional

Count the pipes to find a field, and count the empty ones too: an empty field still holds its place. Leave out the separator before MFI-2 and its value arrives as MFI-1, so the receiver stores Master File Application Identifier as Master File Identifier.

This page carries the MFI field table as published and nothing beyond it. The field notes, vendor behaviour, FHIR mapping and parsing guidance that thePID page has are still to be written for MFI.
