AU Base Encounter Profile [FMM Level 1]
This profile defines an encounter structure including core localisation concepts for use in an Australian context. This profile is intended to be applicable for recording details of ambulatory as well as non-ambulatory patient encounters in an Australian healthcare context.
Extensions used in this profile:
NOTE: AU Base on STU3 included two extensions Encounter Origin Organisation, andEncounter Destination Organisation which are now no longer required as direct R4 support is available.
The official URL for this profile is:
