Recognising ORG messages
ORG announces itself in MSH-9 like this:
ORG^O20^ORG_O20- MSH-9.1
ORGmessage code: what kind of message this is - MSH-9.2
O20trigger event: what happened in the real world: general clinical order acknowledgement message - MSH-9.3
ORG_O20message structure: which segments to expect, and in what order
How to use these specifications explains MSH-9 in full, with a worked example.
