This is a list of the valid subtype codes that are used along with the HL7 message type and event type to uniquely identify a message to the receiving system. It corresponds to the applications' domain or subdomain when a domain has more than one type of message that it will send to VDEF. For example Vitals, Allergies and Lab all send ORU-R01 messages but the contents are vastly different. Each will use a different subtype to make the messages unique. Examples: ORU-R01-VTLS (vitals), ORU-R01-CHEM (lab chemistry) Developers must consult with representatives of DaIS before adding entries to this file.
