What is Protected Health Information (PHI)?

Protected health Information (PHI) is information that health care providers and organizations must not, to protect the privacy of patients, disclose.

If you are sharing medical data (such as in our Share-Your-Brain Contest) you must first delete all of the following: patient names, addresses, phones, emails, medical record numbers, and other unique identifiers.

If you want the exact details, here is the text of Section 1171 of Part C of Subtitle F of Public Law 104-191 (August 21, 1996): Health Insurance Portability and Accountability Act of 1996: Administrative Simplification. It says that you must delete:
