Which of the following is not considered Protected Health Information (PHI)?

Protected Health Information (PHI) refers to any information in a medical context that can be used to identify an individual and that is related to their health condition, healthcare provision, or payment for healthcare. PHI is defined by regulations under the Health Insurance Portability and Accountability Act (HIPAA).

A library card does not fall under the definition of PHI because it typically does not relate to a person’s health status, healthcare provision, or payment for healthcare services. It is simply a means of identifying a patron of a library and does not include any health-related information that could be used to identify or link to an individual’s medical records or healthcare data.

In contrast, a Social Security Number, medical records, and an insurance policy number are all considered PHI, as they contain identifiable information tied to a person's health or healthcare services they receive. Therefore, the library card is the only item on that list that does not meet the criteria of PHI.
