It shows how the Radiotherapy model is mapped into this guide

Mapping from (not specified) to (not specified)

Group 1 Mapping from Radiotherapy to Procedure: Radiotherapy

Comment

diagnosisReference (Diagnosis reference (M))

Procedure.reasonReference

episodeEventReference (Episode Event reference (M))

Procedure.reasonReference

radiotherapyHospital (Radiotherapy Hospital (M))

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

radiotherapyHospital (Radiotherapy Hospital (M))

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.

intent (Intent (M))

Procedure.extension:procedureIntent

from mcode https://build.fhir.org/ig/HL7/fhir-mCODE-ig/StructureDefinition-mcode-radiotherapy-course-summary.html

setting (Setting (M (only if Intent is Curative OR Unknown)))

is equivalent to
