Two years ago, the U.S. Department of Health and Human Services (HHS) Office of the National Coordinator (ONC) issued regulations under the 21st Century Cures Act advancing the interoperability of electronic health information (EHI) and access to EHI by patients and interested stakeholders. These regulations (known as the ONC Cures Act “Information Blocking Rule”) established conditions under which providers, developers of certified health IT, and health information networks and exchanges cannot knowingly engage in practices likely to interfere with the access, exchange, or use of electronic health information.
