Which item is NOT listed as an example of confidential health information processed by cancer registries?

• A. Zip code
• B. Names
• C. Addresses
• D. Health plan beneficiary information

Answer: (A)

Confidential health information in cancer registries includes data that can directly identify a person or tie them to health details, such as names and full addresses, and information tied to their health plan, like health plan beneficiary numbers. These pieces are protected because they uniquely identify individuals or reveal their health coverage.

Zip code is a geographic identifier. On its own, it doesn’t directly identify a person the way a name or a full address does, and privacy guidelines often treat geographic data as less inherently identifying unless combined with other identifiers. Because of that, in this context zip code isn’t listed as an example of confidential health information processed by cancer registries, making it the item that does not fit with the others.
