# Common Order (ORC)
Ordering Provider Matching Ordering Provider NPI is used to find the physician who is responsible for the incoming report. If more than one match is found (e.g. physician works in two different locations and has multiple Elation accounts), we look for the physician who is the primary care provider for the target patient. If the ordering provider and copied provider (OBR 28.1) are both not Elation providers, the result will not deliver to an Elation practice.
Elation only permits one ORC segment in each HL7 message.
