Which of the following is NOT considered PHI?

Protected Health Information (PHI) encompasses any individually identifiable health information that is transmitted or maintained in any form or medium. This typically includes medical histories, names, treatment plans, and other unique identifiers.

Publicly available health statistics, however, do not fall under the definition of PHI because they are aggregated data that do not allow for the identification of an individual. Such data is compiled often for research, policy-making, or public health monitoring purposes and is intended to provide insights at a population level rather than focusing on individual health details. Therefore, the key distinction lies in the ability to identify an individual—publicly available health statistics do not meet this criterion, making this option the correct answer for what is NOT considered PHI.
