Navigating the complexities of health information privacy is crucial for researchers and healthcare professionals alike. The protections surrounding sensitive health data ensure patient confidentiality while allowing valuable research to progress. This detailed overview explains what constitutes protected health information (PHI), what data falls outside its scope, and the specific identifiers that require safeguarding under HIPAA regulations. Awareness of these distinctions and standards is essential for compliance and ethical research practices.
Definition of PHI
Protected health information (PHI) refers to any individually identifiable health data contained within a medical record or designated record set. This information must have been created, used, or disclosed during the provision of healthcare services such as diagnosis, treatment, payment, or healthcare operations. Under HIPAA regulations, researchers may access and utilize PHI when necessary for scientific investigations, provided they adhere to legal standards. However, HIPAA’s scope is limited to data that directly enters the medical record or is involved in healthcare-related activities.
For instance, PHI is often used in retrospective studies that involve reviewing existing medical records for research purposes. It is also generated during research that involves diagnosing health conditions, evaluating new medications or devices, and submitting clinical trial data to agencies like the U.S. Food and Drug Administration. Such activities are subject to HIPAA rules, which aim to protect patient privacy while facilitating medical research.
Researchers should also recognize that student health records at institutions receiving U.S. Department of Education funding are classified as “education records” under FERPA, a separate privacy law. These records, whether maintained by University Health Services (UHS) or optometry clinics, are subject to FERPA protections, whereas non-student health data falls under HIPAA regulations.
What Is Not PHI?
While some health-related data may include personal identifiers such as names or addresses, not all such information qualifies as PHI. Data that is personally identifiable but not linked to a healthcare service event, like treatment or billing, is considered outside HIPAA’s jurisdiction. This includes research data that contains personal identifiers but isn’t integrated into medical records or used in healthcare delivery.
Examples of research involving only health information not classified as PHI include aggregated datasets that do not identify individuals, diagnostic results that are not entered into medical records, and tests conducted without disclosing personal identifiers. Basic genetic research, such as exploring potential genetic markers, typically falls into this category if it does not involve clinical diagnosis or treatment. Conversely, genetic testing used for diagnosing or managing health conditions constitutes PHI and is governed by HIPAA.
Additionally, health information that lacks the 18 specific identifiers—such as vital signs recorded separately—may not be considered PHI unless these data include identifiers like medical record numbers. If identifiers are present, the entire dataset becomes protected under HIPAA.
List of 18 Identifiers
HIPAA defines 18 specific identifiers that, if associated with health information, render it as PHI. Protecting these identifiers is key to maintaining patient privacy:
1. Names
2. Geographical details smaller than a state, including street addresses, city, county, ZIP code (with specific conditions), and geocodes
3. All elements of dates related to an individual (birth, admission, discharge, death), and ages over 89, or any age element indicating such age, unless aggregated into a 90+ category
4. Phone numbers
5. Fax numbers
6. Email addresses
7. Social Security numbers
8. Medical record numbers
9. Health plan beneficiary numbers
10. Account numbers
11. License or certificate numbers
12. Vehicle identifiers, serial numbers, and license plates
13. Device identifiers and serial numbers
14. Web URLs
15. IP addresses
16. Biometric identifiers such as fingerprints and voice prints
17. Photographic images of the full face or similar images
18. Any other unique code or number that can identify an individual (excluding investigator-assigned codes)
To further protect individuals from re-identification, standards prohibit the use of codes derived from personal information or easily linked data. The master codes used in datasets must be created in a way that cannot be reverse-engineered to reveal identities. For example, using initials derived from a name as a code is not acceptable because it can be traced back to the individual.

Compliance with these standards is detailed in the CPHS HIPAA Guidance and related policies. Understanding the nuances of health data privacy laws helps ensure ethical research and protects patient rights.
