- United States Core Data for Interoperability (USCDI) | Interoperability Standards Advisory (ISA) (healthit.gov) is a standardized set of health data classes and data elements for nationwide (US), interoperability health information exchange. USCDI is updated annually.
-
- Certification of Electronic Health Record exchange APIs requires use of USCDI version 2; use of version 3 will be required as of December 31, 2025. Current adoption by EHRs can be found here: adoption by EHRs.
-
- Timeline – initial input closes September; version for public comment February – April; publishes every July.
-
- NOTE: The HL7 US Core Implementation Guide is released about one year after USCDI.
- USCDI+ is not required for EHR certification but includes specialized use cases, such as public health. You can create an account to add comments.
-
- Intended to fill the gaps for quality, public health, providers, behavioral health, etc.
-
- Much more flexible – but on an annual time frame to make it easier for vendors.
-
- Established domains, including maternal health and public health.
- USCDI+ Cancer is currently working on several cancer use cases, and recently closed its public comment period for cancer registry data elements. Please see the following link for information from the May 2024 USCDI+ Cancer Data Exchange Summit: Cancer Research Data Exchange Summit (Overview) | Events Registration and the Cancer Registry listening session held in August 2024: USCDI+ Knowledge – Announcement: Cancer Registry Listening Session – August 29th – USCDI+ Service Portal.

US Core Implementation Guide (HL7) defines the minimum constraints on FHIR to implement USCDI. The latest version can be found here: HL7.FHIR.US.CORE\Home – FHIR v4.0.1. It provides more specificity and guidance than USCDI. Many other HL7 standards are built off of the US Core Implementation Guide. Note: The update cycles for USCDI and US Core are different, so the standards are not always 100% aligned.
- US Public Health Profiles Library (HL7) is a collection of reusable architecture and content profiles representing common public health concepts and patterns. It is intended as a complement to the US Core Implementation Guide to meet reporting requirements for public health. The latest version can be found here: Home Page – US Public Health Profiles Library v1.0.0.
- Minimal Common Oncology Data Elements (mCODE): HL7.FHIR.US.MCODE\Home – FHIR v4.0.1. Uses ~30 FHIR profiles that cover patient, disease, health assessment, genomics, cancer treatment and outcomes. mCODE defines relationships between the profiles and is intended to be used in implementation guides that further specify what information is required for a patient for different uses.
- Making Electronic Data More Available for Research and Public Health (MedMorph) has two separate Implementation Guides of interest:
- MedMorph Implementation Guide: HL7.FHIR.US.MEDMORPH\MedMorph Home Page – FHIR v4.0.1 provides a common method for obtaining data for research and public health. It is aligned with HL7 FHIR and TEFCA. It defines API mechanisms, methods to trigger workflows, reporting and privacy services.
- Central Cancer Registry Reporting Content Implementation Guide specifies how the MedMorph Reporting IG is to be used to enable automated, standardized exchange of cancer surveillance data from ambulatory health provider EHR systems to Central Cancer Registries. It makes use of mCODE. See HL7.FHIR.US.CENTRAL-CANCER-REGISTRY-REPORTING\Detailed Specification – FHIR v4.0.1.
- Cancer Pathology Data Sharing Implementation Guide provides HL7 FHIR resources to define standards for cancer pathology information exchange from a hospital or facility-based laboratory information system to a hospital or facility-based electronic health record (EHR) system. See HL7.FHIR.US.CANCER-REPORTING\Home Page – FHIR v4.0.1.

- Health Data, Technology, and Interoperability: Certification Program Updates, Algorithm Transparency, and Information Sharing (HTI-1) Final Rule | HealthIT.gov implements provisions of the 21st Century Cures Act and includes updates to Electronic Health Record (EHR) certification criteria, standards and provisions to minimize information blocking. Latest version was enacted on December 13, 2023.
- (DRAFT) Health Data, Technology, and Interoperability: Patient Engagement, Information Sharing, and Public Health Interoperability (HTI-2) Proposed Rule | HealthIT.gov underwent a public comment period that closed October 4, 2024. It updates the requirements for certified electronic health records and includes implementation guide updates for ambulatory and pathology reporting to central cancer registries.
