This IG provides detailed guidance that helps implementers use FHIR-based interactions to support specific clinical data exchanges between providers and payers (or other providers). This guide documents the Direct Query, Task Based, and Attachments transaction approaches for requesting and sending information. Key scenarios this IG can support include:
In the context of this guide, "clinical data" means any information a provider holds in a patient's health record. The data exchange format is not limited to FHIR resources but includes C-CDA documents, PDFs, text files, and other formats. Implementers can request and receive clinical records of care such as CCD Documents or C-CDA on FHIR Documents, clinical data sets represented by a FHIR Bundle, FHIR QuestionnaireResponse, and other types of FHIR resources.
By using the FHIR standard and implementing this guide, payers can be explicit about the data they are requesting instead of general requests, which avoids sending more information than necessary. As a result, the anticipated benefit of using FHIR is a more efficient and effective exchange of health record information in several areas, such as claims management, care coordination, risk adjustment, and quality reporting.
This IG provides several generic examples to illustrate the Direct Query and Task-Based approaches to exchanging clinical data. It also documents and provides examples for Requesting and Sending Attachments for claims and prior authorization. We also plan to create Clinical Data Exchange - Supplemental Guides, which will document and provide examples for other specific use cases.
The Da Vinci initiative supports this implementation guide. Da Vinci is a private effort to accelerate the adoption of Health Level Seven International Fast Healthcare Interoperability Resources (HL7® FHIR®) as the standard to support and integrate value-based care (VBC) data exchange across communities. This guide and implementers of it SHALL adhere to the HL7 Da Vinci Guiding Principles for exchanging patient health information.
As illustrated in Figure 1 below, this version of CDex is based on FHIR R4, and much of its content is dependent upon the [Da Vinci Health Record Exchange (HRex), US Core 3.1.1 (FHIR R4), US Core 6.1.0 (FHIR R4), and , US Core 7.0.0 (FHIR R4)implementation guides. For general Background on FHIR, Conformance Expectations, and Security and Privacy considerations, refer to the corresponding sections in HRex. US Core 3.1 meets regulatory requirements mandating support for ONC United States Core Data for Interoperability V1 (USCDI V1), US Core 6.1.0 meets regulatory requirements mandating support for ONC United States Core Data for Interoperability V3 (USCDI V3)], and US Core 7.0.0 meets regulatory requirements mandating support for ONC United States Core Data for Interoperability V4 (USCDI V4)]. For Direct Query and Task-Based queries, US Core and HRex define the underlying content, and CDex provides additional context, definitions, and constraints. CDex provides more focused use cases by constraining profiles and extending functionality to cover gaps. For example, CDex defines all the content for Attachments.
