The receiving system uses this field to know the data segments to recognize and, possibly, the application to which to route this message. This should be set to “ORU^R01”

10

Message control ID

Processing ID

R

Used to decide how to process the message as defined in HL7 processing rules. Field appears as: P for production,  T for training, or  D for debugging

12

Version ID
