... diagnosisReference
... episodeEventReference
... radiotherapyHospital
  • ​Related To Procedure.performer (In case the actual Organization performing the procedure is captured. It could be a perfomer of type Organization; or a perfomer.organization if of type PractitionerRole)
  • Related To Procedure.extension:sameHospital (Temporary included in the guide for covering the request of tracking if this information has been captured and maintained by the same or other organizations. It is envisioned that this kind of requirements could be covered by recording where specific act are taking place.)
