Protected Health InformationPHI
Protected health information (PHI) is individually identifiable health information a covered entity or business associate holds or transmits in any form, electronic, paper, or oral. Under 45 CFR 160.103 it excludes education records governed by FERPA, employment records held by an employer, and information about someone deceased more than 50 years.

What PHI means under HIPAA
PHI is the thing HIPAA exists to protect. The definition in 45 CFR 160.103 has two moving parts: the information must be individually identifiable health information (it relates to someone’s health, care, or payment for care, and could reasonably identify them), and it must be created, received, maintained, or transmitted by a covered entity or business associate. Electronic PHI is sometimes written ePHI, but the format does not change whether it is PHI: a paper chart, a voicemail, and a database row can all be PHI.
The exclusions matter as much as the definition. FERPA education records, records covered by 20 U.S.C. 1232g(a)(4)(B)(iv), employment records a covered entity holds as an employer, and information about a person dead more than 50 years are not PHI. That is why a school-based therapist’s records are often FERPA education records rather than HIPAA PHI, and why your own HR files are not PHI even though you are a covered entity.
Almost every other HIPAA obligation is downstream of this definition. Your Security Risk Analysis has to cover every system that touches PHI, your Notice of Privacy Practices describes how you use it, and your Business Associate Agreements exist because a vendor will handle it. If you can map where PHI lives in your practice, the rest of the binder follows.

Whether HIPAA applies to your practice depends on the covered-entity test. State law may add stronger requirements.
