This tutorial covers the definition of Protected Health Information (PHI) and is the third of 24 lessons. When HIPAA was enacted in 1996, Congress intended to protect the privacy of "individually identifiable health information" (IIHI). The phrase was later shortened to "protected health information" (PHI). IIHI and PHI terminology is used interchangeably. This website is specifically designed for small entities in California. Each tutorial is narrated by Carol Mack, RN, attorney at law.
