Recently Published: CodeX Radiation Therapy Implementation Guide (STU 1)

Linked here

This publication marks the completion of a multi-year project conducted by the CodeX Radiation Therapy use case team to develop an implementation guide that describes how to represent, model, and exchange radiation therapy (RT) information that is generated during a patient’s RT planning and treatment. 

Project Overview


  • Radiation therapy treatment details – critical for care coordination – are not readily available in systems other than radiation oncology EHR modules.
  • Treatment data is generally manually entered into radiation therapy treatment summary documents, creating clinician burden and potential patient safety issues.
  • Additionally, providers are unable to leverage these data to meet reporting requirements (e.g. quality reporting, registry reporting) or support comparative effectiveness research.


  • Radiation oncologist adds all in-progress and end-of-treatment radiation therapy summary details into the radiation oncology information system. 
  • The radiation oncology information system is able to take this radiation information and generate a treatment summary report, either an in-progress or end-of-treatment report
  • Once the treatment summary report is generated, the radiation oncology information system is able to send this treatment summary to a radiation oncology resource repository (FHIR server) 
  • And then an Observer (user), either another radiation oncology information system or an EHR vendor system, can retrieve the treatment summary information that matches the search parameters sent to the radiation oncology resource repository 

Target Outcome: 

  • To develop, test and deploy open data standards that enable interoperable, multi-purpose exchange of radiation treatment summary data for care coordination and data reuse
    • such as quality management, research, and payer-required reporting 
  • And enable radiation oncology information system to generate treatment summaries that are retrievable by health systems, other information systems, and displayed within the EHR interface 


  • Radiation oncology information systems will be able to seamlessly generate and share patients' radiation therapy treatment summary information, both end-of-treatment and in-progress summary data, across health systems and providers.
  • Clinicians can then use this readily available radiation therapy treatment summary information to make informed, impactful decisions related to a patient's health, by leveraging this information to support comparative effectiveness research, meet reporting requirements, and improve patient safety

Plan out high level project plan, deliverables, success measures, high level timeline, key stakeholders, etc


Phase 0

Define and expand the radiation therapy concepts in mCODE, in preparation for mCODE STU 2


Phase 1 

Radiation oncology system generates end of treatment summary that can be retrieved by another information system

Phase 2

Radiation oncology system generates radiation therapy in-progress treatment summaries that can be retrieved by another information system or health system

Phase 3

Radiation oncology system generates treatment summaries that are retrieved by a health system and displayed within the EHR interface
