The Office of the National Coordinator for Health Information Technology’s (ONC) 21st Century Cures Act Information Blocking Rule (Info Blocking Rule) prohibits covered actors – including health care providers, health IT developers of certified health IT, and health information exchanges/health information networks– from engaging in practices likely to interfere with, prevent, or materially discourage access, exchange, or use of electronic health information (EHI). The Info Blocking Rule includes eight exceptions that provide actors with certainty that, when their practice interferes with the access, exchange, or use of EHI and meets the conditions of one or more exception, such practice will not be considered information blocking. An actor’s practice that does not meet all the conditions of an exception will be evaluated on a case-by-case basis to determine whether information blocking has occurred.
