Mapping Between Vocabularies

The concepts in this value set are drawn in priority order first from SNOMED CT (SCT), second from UMLS Metathesaurus, and lastly, from the radiotherapy code system defined in this Implementation Guide. Missing SNOMED CT codes have been submitted for approval.

The following table shows potential mappings. This table may not be exhaustive and additional valid mappings may exist.

SNOMED CT Term UMLS Metathesaurus Term Radiotherapy Code System
10611004 “Teleradiotherapy protons (procedure)” C0436226 “Proton Therapy” not needed
45643008 “Teleradiotherapy using electrons (procedure)” C0454077 “Teleradiotherapy using electrons” not needed
80347004 “Teleradiotherapy neutrons (procedure)” C0278623 “High-LET Neutron Therapy” not needed
Missing [1] C3494442 “Carbon Ion Radiotherapy” not needed
Missing [2] C3539769 “Photon Beam Radiation Therapy” not needed

Notes:

  1. 312248006 “Heavy ion teletherapy (procedure)” is a broader term, although today, carbon ions are the predominant heavy ions used in EBRT.
  2. 448385000 “Megavoltage radiation therapy using photons (procedure)” and 169291001 “X-ray beam therapy (procedure)” are narrower terms and there may be treatment situations involving photons that cannot be described by either term.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
