Introduction
Protected Health Information (PHI) is the backbone of privacy in healthcare. Governed by the Health Insurance Portability and Accountability Act (HIPAA), PHI encompasses any identifiable health data managed by healthcare providers, insurers, and their vendors. Ensuring PHI is secure isn’t just a legal requirement—it’s critical for maintaining trust and avoiding costly breaches.
This guide provides a clear definition of PHI, examples across industries, a full list of HIPAA’s 18 identifiers, and practical steps to secure it. Whether you’re a healthcare provider, insurer, or tech vendor, you’ll gain actionable insights to protect patient data effectively.
What is PHI?
Definition: Protected Health Information (PHI) includes any health information that can identify an individual and is used, maintained, stored, or transmitted by a HIPAA-covered entity or business associate. This information relates to an individual's past, present, or future physical or mental health or condition and the provision of healthcare.
HIPAA's 18 PHI Identifiers
HIPAA explicitly identifies the following as PHI when they are linked to health information:
- Names
- Geographic Data: All geographic subdivisions smaller than a state, including street address, city, county, and ZIP code.
- Dates: All elements of dates (except year) related to an individual, such as birth date, admission date, discharge date.
- Telephone Numbers
- Fax Numbers
- Email Addresses
- Social Security Numbers
- Medical Record Numbers
- Health Plan Beneficiary Numbers
- Account Numbers
- Certificate/License Numbers
- Vehicle Identifiers: Including license plate numbers.
- Device Identifiers and Serial Numbers
- Web URLs
- Internet Protocol (IP) Addresses
- Biometric Identifiers: Such as fingerprints or voiceprints.
- Full-Face Photographic Images
- Any Other Unique Identifying Number or Code
Quick Tip: If health information includes any of these identifiers, it's considered PHI and must be protected according to HIPAA regulations.
Examples of PHI
Healthcare Settings:
- Clinical Records: A patient’s treatment plan containing their name, diagnosis, and prescribed medications.
- Lab Results: A COVID-19 test result tied to a patient’s unique ID.
