Draft as of 2026-11-01 Computable Name: ImagingOrder

FHIR Message equivalent of the IHE SWF.b HL7 v2.5.1 OMG^O19^OMG_O19 order message, sent by the Order Placer for Placer Order Management [RAD-2] and by the Order Filler for Filler Order Management [RAD-3]. The order control (ORC-1) and order status (ORC-5) are carried by the Radiology Service Request:

Transaction ORC-1 ServiceRequest
RAD-2 new order NW status active, placer order number
RAD-2 change order XO updated ServiceRequest
RAD-2 cancel order CA status revoked
RAD-3 new filler order SN status active, filler order number and accession number
RAD-3 change order XX updated ServiceRequest
RAD-3 status change SC status from ORC-5
RAD-3 cancel OC status revoked

The code-by-code ORC-1 / ORC-5 mapping to ServiceRequest.status is Open.

The HL7 v2 acknowledgement ORG^O20^ORG_O20 is a FHIR response message (MessageHeader.response) - from the Order Filler for RAD-2, returning the ServiceRequest with the filler order number; from the Order Placer for RAD-3, returning the placer order number.
