Shared Health Specification and Guide Version 5.0

Allows a communication to reference the group of Medication Orders found in the bundle

Usage Note: This is used to identify the bundle that the communication is related too (e.g. Communications pertains to an entire Prescription i.e. multiple medication orders). Only the Group business identifier is included, the entire message bundle is not included. This is used to associate and link communications to the proper bundle in order to facilitate having a complete view of communication in context of the entire bundle that it is referring to.

Conformance Rule:

(1) When creating a communication that is linked to an entire message bundle (e.g. prescription), the group identifier must be in the same format and have the same value as it was sent or received in the original bundle's Task.extension(groupIdentifier).

(2) When receiving a communication and this element is populated, the system must use this value to find the corresponding bundle or all the tasks related to that bundle (e.g. multiple medication orders) in the receiving system to associate and link that incoming communication with in order to facilitate having that complete view of the context involved.

(3) When replying to a communication and this element is populated, the system must resend the data as it was received.

(4) Communication.extension(topic) and Communication.extension(topicGroup) must never be populated together, only one or the other extension can be populated depending on what needs to be referenced.

unique id for the element within a resource (for internal references).
