The U.S. Department of Health and Human Services through the Office of the National Coordinator for Health Information Technology (ONC) finalized its rule to advance health IT interoperability and algorithm transparency.

Finalized on Dec. 13, the Health Data, Technology, and Interoperability: Certification Program Updates, Algorithm Transparency, and Information Sharing (HTI-1) rule comes after the April 2023 release of the proposal. It includes provisions of the 21st Century Cures Act to “advance interoperability, improve transparency, and support the access, exchange, and use of electronic health information.”

The HTI-1 rule implements transparency requirements for artificial intelligence and other predictive algorithms; adopts the United States Core Data for Interoperability Version 3 as the baseline standard within the ONC Health IT Certification Program effective Jan. 1, 2026; revises information blocking requirements; and enacts a requirement for developers to report specific metrics as part of their participation in the certification program.

The submission of HTI-1 to the Office of the Federal Register is forthcoming.
