Which of the following is an example of Individually Identifiable Health Information?

Individually Identifiable Health Information refers to any data that can be used to identify an individual and is related to their health status or healthcare. A street address qualifies as it is a direct piece of information that can pinpoint where an individual lives. This makes it identifiable and able to connect the information to a specific person, which is crucial when considering the protection of such data under HIPAA regulations.

The other options do not qualify as Individually Identifiable Health Information in the same way. A social media username may represent an individual's online identity but does not specifically relate to their health information. A favorite color is a neutral piece of data that is unrelated to health or personal identification in a medical context. Geographic location, while it can be linked to an individual, is often too broad (for instance, stating a city) and does not directly tie back to health information without additional context. Hence, street address stands out as the most appropriate example of Individually Identifiable Health Information.
