Which of the following is considered Protected Health Information (PHI)?

Protected Health Information (PHI) encompasses a broad range of data that can identify a patient and relates to their health status, treatment, or payment for healthcare services. The correct answer highlights that any information that can identify a patient qualifies as PHI. This includes not only demographic details like the patient's name and address but also various aspects such as age, birth date, social security number, and specific medical history.

The significance of this definition lies in the comprehensive nature of what constitutes PHI; it is not limited to just medical records but extends to any identifiable information related to the patient. In terms of compliance with HIPAA regulations, understanding that PHI is a collective term helps ensure that all forms of identifiable health information are protected appropriately.
