Is electronic health information (EHI) that is covered by the information blocking regulations limited by when the information was generated?

No, the definition of electronic health information (EHI) is not limited by when the information was generated. Before October 6, 2022, an actor must respond to a request to access, exchange, or use EHI with, at a minimum, the requested EHI that they have and that can be identified by the data elements represented in the United States Core Data for Interoperability (USCDI), regardless of when the information was generated. On and after October 6, 2022, an actor must respond to a request to access, exchange, or use EHI with EHI as defined in 45 CFR 171.102, regardless of when the information was generated. For example, an actor who has the necessary technical capability to do so is required to fulfill a request to access, exchange or use EHI that they have and could appropriately disclose in response to that request even if the EHI was generated before the ONC Cures Act Final Rule was published and even if the EHI was generated before the Cures Act was enacted by Congress.
