It contains the trigger code which is the same as the trigger code in the resource and is used to identify which code(s) in a resource that allows multiple trigger codes (e.g. US Core Observation Lab where a trigger code could be contained in either the code (lab test) or the value (lab test result) or in the case of a battery or panel of tests, in the hasMember as another US Core Observation Lab code or value). It also contains the RCTC OID and RCTC version of the value set from which the code was matched.

It is available for use in the following places:

• eICR Encounter
  • flags a code contained in Condition.code US Public Health Condition Encounter Diagnosis which is contained in Encounter.diagnosis eICR Encounter - diagnosis
• Problem Section entry
  • flags a code contained in Condition.code (US Public Health Condition Problems and Health Concerns) - diagnosis
• Plan of Treatment Section entry
  • flags a code contained in ServiceRequest.code eICR ServiceRequest - test being requested
• Results Section entry
  • flags codes contained in:
    • Observation.code US Public Health Laboratory Result Observation Profile code - test performed/battery or panel name
    • Observation.value US Public Health Laboratory Result Observation Profile code - test result
    • Observation.code referenced in containing Observation.hasMember US Public Health Laboratory Result Observation Profile code - member of panel test performed
    • Observation.value referenced in containing Observation.hasMember US Public Health Laboratory Result Observation Profile code - member of panel test result
• Medications Section entry
  • flags a code contained in MedicationAdministration.medicationCodeableConcept US Public Health MedicationAdministration - medication
• Immunization Section entry

Summary

Complex Extension: This Extension profile represents a flag which, if it is present, indicates that the target reference represents a triggering event and caused the eCR to be generated.

• triggerCodeValueSet: string: RCTC value set OID (as a string)
• triggerCodeValueSetVersion: string: RCTC value set version
• triggerCode: Coding: Trigger code - this code is the same as the trigger code in the resource and is used to identify which code(s) in a resource that allows multiple trigger codes (e.g. US Core Observation Lab where a trigger code could be contained in either the code (lab test) or the value (lab test result) or in the case of a battery or panel of tests, in the hasMember as another US Core Observation Lab code or value).
