PHI, ePHI, and EHI – Oh my!
There is no time like the present to review these definitions and understand their relation to information blocking
Recently, I was presenting at a conference and posed the question to the audience – “do you know what a designated health record set is and why it is important in medical record requests?”
Most people have neither heard of the term “designated health record set” (DHRS) nor are they familiar with the term electronic health information (EHI) and how it relates to protected health information (PHI), electronic health information (ePHI), and electronic health information (EHI). In light of the October 6, 2022 lifting of the limitation on the scope of EHI, there is no time like the present to review these four (4) definitions and understand their relation to information blocking.

[Basically, any form of electronic media as defined in this portion of the CFR.]
- EHI(
45 CFR § 171.102 ) - is defined as the electronic protected health information (ePHI) in a designated record set (as defined in the Health Insurance Portability and Accountability Act (HIPAA) regulations) regardless of whether the records are used or maintained by or for a covered entity.
