Which of the following is considered PHI under HIPAA?

Protected Health Information (PHI) under HIPAA is defined as any information about health status, healthcare provision, or payment for healthcare that can be linked to an individual. Appointment scheduling information is considered PHI because it includes details that can directly relate to an individual's healthcare and can be used to identify that individual. This information indicates when and where a healthcare service is being provided, thus reflecting the individual's health-related activities and potentially linking their identity to their medical care.

Anonymous health data does not fall under the definition of PHI as it does not contain any identifiers that could connect the data back to an individual. Public health information varies based on context but typically does not include identifiable health information. Financial records of a healthcare entity pertain to the organization itself rather than health information about specific individuals.
