Which of the following describes Protected Health Information (PHI)?

Protected Health Information (PHI) refers specifically to health information that can identify an individual. This includes details such as names, addresses, birth dates, Social Security numbers, and any other data that, when combined with health information, can lead to the identification of a person. Recognizing PHI is crucial because it is subject to strict regulations under HIPAA, which aim to protect an individual's privacy and ensure the confidentiality of their health information.

The other options do not accurately capture the essence of PHI. While confidentiality is important in healthcare, simply being kept confidential for legal purposes does not specifically define PHI, as it encompasses a wider range of information that might not directly relate to an individual's health. Additionally, stating that information is available to all healthcare workers or that it is unrestricted in healthcare settings contradicts the very principles of PHI protection, which is designed to limit access to authorized individuals only. This distinction is vital for maintaining patient trust and upholding legal standards in healthcare.
