RRI: Return referral information
This page lists the structures and trigger events RRI defines, taken from the standard. The written commentary that theADT page carries has not been written for RRI.
Recognising RRI messages
RRI announces itself in MSH-9 like this:
RRI^I12^RRI_I12- MSH-9.1
RRImessage code: what kind of message this is - MSH-9.2
I12trigger event: what happened in the real world: patient referral - MSH-9.3
RRI_I12message structure: which segments to expect, and in what order
How to use these specifications explains MSH-9 in full, with a worked example.
Message structures
RRI takes 1 structure.
RRI_I12: Patient Referral

R inside a group means required of that group. Send the group and you must include that segment; leave the group out and it never appears. This structure has 7 such groups: AUTHORIZATION_CONTACT, PROVIDER_CONTACT, PROCEDURE, AUTHORIZATION_CONTACT, OBSERVATION, RESULTS_NOTES, PATIENT_VISIT.
