It is theindicator used to send data at two levels, visit and account. IHE PCD implementationsshall send an ‘A’ or no value when the data in the message are at the account level, or ‘V’to indicate that the data sent in the message are at the visit level.The value of this element affects the context of data sent in PV1, PV2 and any associatedhierarchical segments (e.g. DB1, AL1, DG1, etc.).B.7 OBR – Observation Request segment1020In the reporting of clinical data, the Observation Request Segment (OBR) serves as thereport header. It identifies the observation set represented by the following atomicobservations. It includes the relevant ordering information when that applies and manyof the attributes that apply to all of the following observations.Use as specified in HL7 – place here all header information for report content – asdistinct from MSH above which covers both patient and report info.
