What is electronic protected health information (ePHI)?

According to the US Department of Health and Human Services, electronic protected health information (ePHI) is any protected health information (PHI) that is created, stored, transmitted, or received electronically. All protected health information is subject to federal Health Insurance Portability and Accountability Act (HIPAA) regulation, which refers to any information that identifies an individual (usually a patient) and relates to at least one of the following:

  • The individual's past, present, or future physical or mental health
  • The provision of health care to the individual
  • Past, present, or future payment for health care

Information that can identify an individual includes either the individual's name or any other information that could enable someone to determine the individual's identity.

Data are "individually identifiable" if they include any of the 18 types of identifiers for an individual or for the individual's employer or family member, or if the provider or researcher is aware that the information could be used, either alone or in combination with other information, to identify an individual. These identifiers are:

  • Name
  • Address (all geographic subdivisions smaller than state, including street address, city, county, or ZIP code)
  • All elements (except years) of dates related to an individual (including birth date, admission date, discharge date, date of death, and exact age if over 89)
  • Telephone numbers
  • FAX number
  • Email address
  • Social Security number
  • Medical record number
  • Health plan beneficiary number
  • Account number
  • Certificate/license number
  • Any vehicle or other device serial number
  • Device identifiers or serial numbers
  • Web URL
  • IP address
  • Finger or voice prints
  • Photographic images
  • Any other characteristic that could uniquely identify the individual

In research, it is often sufficient to make the information more general (instead of being removed altogether) for de-identification (e.g., by replacing the birth date with an age range).

The "e" in ePHI

Electronic protected health information (ePHI) includes any medium used to store, transmit, or receive PHI electronically. The following and any future technologies used for accessing, transmitting, or receiving PHI electronically are covered by the HIPAA Security Rule:

  • Media containing data at rest (storage)

    • Personal computers with their internal hard drives used at work, home, or traveling
    • External portable hard drives, including iPods and similar devices
    • Magnetic tape
    • Removable storage devices, such as USB memory sticks, CDs, DVDs, and floppy disks
    • PDAs and smartphones

  • Data in transit, via wireless, Ethernet, modem, DSL, or cable network connections

    • Email
    • File transfer
