Understanding what constitutes Personally Identifiable Information (PII) within the healthcare sector is vital for both providers and patients. While often confused with Protected Health Information (PHI), PII refers specifically to non-health-related data that can identify an individual but is held separately from medical records. Proper knowledge of these distinctions helps prevent privacy breaches and ensures compliance with legal standards such as HIPAA.
In healthcare, it is essential to understand the concept of a designated record set. According to HIPAA (45 CFR §164.501), this term defines a collection of medical or billing records maintained by or for a covered entity. These records are used for making decisions about individuals and include sensitive health information, diagnoses, treatments, and payment details—effectively, the scope of individually identifiable health information as outlined in HIPAA (45 CFR §160.103). The definition emphasizes that a designated record set can range from a single document to an extensive collection comprising hundreds of records.
For example, a doctor reviewing a patient’s decade-long medical history, which includes examinations, test results, and treatment outcomes, is accessing a designated record set. Similarly, a photo of a newborn displayed in a healthcare setting is also considered part of this set, as it contains identifiable health information about a past medical event. This illustrates the broad scope of what can be classified as a designated record set.
Designated Record Sets, PHI, and PII
Any individually identifiable health information stored within a designated record set qualifies as PHI when created or received by a covered entity or business associate, provided it doesn’t meet specific exemption criteria (such as records covered under FERPA or maintained solely for employment purposes). For instance, health records that include a patient’s name, diagnosis, and treatment details are protected under HIPAA.
HIPAA also clarifies that if non-health information—like a person’s name or contact details—is stored in the same record set as health data, it gains the same protections as PHI. Conversely, if such non-health details are kept in a separate database without any associated health information, they are considered PII in healthcare. While this PII is still protected under state laws, it does not have the same restrictions on use and disclosure as PHI. This distinction is crucial because it influences how organizations handle and safeguard different types of data.
Examples of PII in Healthcare
Numerous everyday scenarios illustrate how PII can exist independently of health information. When a patient initially contacts a healthcare facility, their name and contact details are often collected through online forms or phone conversations—none of which necessarily contain health or payment information at that stage. These details are stored separately, enabling activities such as scheduling appointments, dispatching home visits, or conducting marketing outreach without exposing sensitive health data.
Physicians, for instance, might maintain a separate list of patients they see socially, such as golf partners, or midwives might keep a record of birth dates to send birthday greetings. Additionally, hospital parking systems that record license plates create databases containing non-medical identifiers. Such data, while personal, fall under the umbrella of PII because they do not directly reveal health information.
The Importance of Recognizing PII in Healthcare
Differentiating between PII and PHI is critical for maintaining patient trust and ensuring compliance with privacy regulations. Misunderstandings can lead to unwarranted complaints about unauthorized disclosures, which burden healthcare organizations and may trigger investigations by authorities like the Office for Civil Rights. Educating healthcare providers about the distinctions, including what constitutes PHI as defined under HIPAA, is essential. Incorporating comprehensive explanations into HIPAA training helps prevent confusion and promotes proper data handling practices.
Furthermore, understanding these differences allows healthcare organizations to implement appropriate safeguards for various types of data, reducing the risk of privacy breaches. For example, when managing non-health-related PII, organizations should still adhere to applicable state laws and best practices for data security. Recognizing the boundaries between PII and PHI enhances overall privacy management and supports legal compliance across the healthcare industry.

Similarly, understanding how new technologies are shaping medical training can be explored through resources on virtual reality in surgical education, and the impact of virtual environments on athletic performance is discussed in studies about sports and virtual reality interactions.
