Event Notes 


USCDI -Rubric Rules – Scorecard Updates 

Session 1 Handout

The United States Core Data for Interoperability (USCDI) standard will replace the Common Clinical Data Set (CCDS) definition 24 months after publication of the final rule (May 1, 2020) - i.e. May 2, 2022.  However the enforcement date has been pushed back three months to August 2, 2022.

The C-CDA Rubric Guide was published on May 19, 2020 - providing guidance for required and informative rubrics and organized into three categories:

  • Common Rubrics
  • Header Rubrics
  • Section/Domain Specific Rubrics

Goal of the Rubrics Guide is to promote the development of quality assessment tools and improve interoperability and secondary use of data.  People can suggest rubrics on the HL7 C-CDA Rubric Criteria Project Page.

ONC C-CDA Scorecard R2.0 Beta Demo.  R2.0 will be pushed out to production on June 1, 2020.  The downloadable scorecard on Github will also be updated.  Updated companion guide templates will be incorporated on June 30, 2020.

Questions related to ONC Cures Act Final Rule can be submitted at and click ONC Cures Act Final Rule box.

Q: Will the validator the rubric is using also be updated by June 1?  A: Yes, but it will not be in the June 1 version of the scorecard.

Q: What is the go-forward process for adding requirements as USCDI grows?  A: Criteria suggestions can be logged on the HL7 C-CDA Rubric Criteria Project Page (link above).  The ONC is committed to updating the scorecard (provided funds are available). 

Q: Are pediatric vitals required for all EHRs or is there a % of children to require EHRs to capture this information?  A: This is a good question for the program.

Q: ONC offer tools for validation of the various clinical notes named in USCDI?  A: Yes...but only for the mandatory templates.

Q: The number of issues is hard to see when you expand format.  A: Yes.  Matt will work with the team to see if there is a clearer way to present the information.

C-CDA for Quality Measures

Session 2 Handout

Data Aggregator Validation: Pilot Program

Goals of the program are to:

  • Ensure integrity of data is maintained from source through to end-user
  • Ensure Aggregator adheres to NCQA Implementation Guide (IG)
  • Minimize audit burden on vendors and health plans who receive data

Aggregators MUST pass both the input data validation and the output file validation in order to be considered validated.

Anticipated timelines- June 2020 for pilot completion, soft launch in the fall and 2021 for the official program launch.

Q: How can we learn from your project putting into consideration we are outside of the US and we rely only on HL7 CDA.  A:  Best way would be reach out to Wendy via email or to visit the NCQA DAV webpage.

Q: What falls into the category of "aggregator"?  A: Includes HIEs, vendors who aggregate and pass through data, etc. but there is not a hard definition.

Q: How does this process/validator work in conjunction or relate to the ONC validator/scorecard?  A: Right now, the validators are different.  However, the goal is to align.  This will be a discussion for for team to see how it can leverage and feed back to the ONC tools.

Q: Is there going to be a mapping document between C-CDA elements and Quality Measure elements?  When an element is required by QM but it is not supported by the CDA IG, will the IG be updated accordingly?  A: xxx

C-CDA on FHIR and transforming C-CDA to FHIR

Session 3 Handout

Session objectives:

  • Key characteristics of clinical documents
  • The FHIR document paradigm
  • How to find and navigate the C-CDA on FHIR specification
  • Challenges mapping between CDA and FHIR documents

Link to FHIR Composition Resource and C-CDA on FHIR Implementation Guide.

Q: Is there use of the list resource in this work?  If not, why? A: It was considered but was deemed unnecessary as much of what is covered in list could be found in section.  Use of list is not prohibited though.

Q: What are the use case differences between documentReference vs. composition? A: documentReference is used for unstructured FHIR content.  Composition is used when you have structured FHIR content. 

Q: Will FHIR document replace C-CDA at some point? A: Hope to move away from "data dump" scenarios such as full CCD exchange between EHRs when using FHIR.  That said, it is unlikely C-CDA will go away any time soon.

Q: We'd like there to be some discussion on how a system should incrementally move towards FHIR. i.e. start with basic context-free queries to replace need for CCDs, while keeping encounter summaries in a document form, incrementally moving from C-CDA to FHIR documents or maintaining both.  A:

Q: Are there any suggestions for addressing negation in CDA→FHIR? A: This is on a resource-by-resource basis.

Top issues from CommonWell – Carequality

Link to Concise Consolidated CDA:Deploying Encounter Summary CDA Documents with Clinical Notes white paper.

Discussion: One possible approach for the Patient Summary (CCD) newly generated scenario: create a new document ID, and then create a parent id of some sort that you need to look at to find the link back to find out that it's the same.  However the intent is not to drive to consensus here - instead it is to highlight issues uncovered.

Discussion: There can be sharing of incomplete encounters - e.g. sharing of anticipated orders prior to a patient being discharged.

These are examples of pain points and issues discovered through the workgroup.  If you want to contribute to driving towards consensus approaches to these issues, Carequality has many committees and workgroups that can be joined. In the spirit of transparency and community, non-members are invited to join many of our workgroups as well. We encourage anyone who would like to participate to contact us at to let us know of your interest. Here is the link to the website listing all workgroups convened by Carequality.
