Protecting sensitive health and personal data remains a top priority for healthcare organizations striving to meet HIPAA requirements. Understanding the distinctions between Protected Health Information (PHI) and Personally Identifiable Information (PII) is essential for establishing effective compliance strategies, reducing risks, and safeguarding patient confidentiality across various regulatory landscapes. This article explores the definitions, examples, and security practices associated with both types of data, offering insights into how organizations can unify their data protection efforts.
PII Definition and Examples
As the name indicates, Personally Identifiable Information (PII) encompasses any data that can be used to identify an individual. Common examples include full names, dates of birth, addresses, and biometric identifiers, which are always regarded as sensitive. However, other pieces of information—such as a first name, initials combined with last names, or physical attributes like height and weight—may only qualify as PII under certain circumstances or when combined with other data.
For instance, a record stating “Mr. Smith in New York” might not reveal enough to identify the individual. Conversely, if the name is uncommon and the location is a small community, this information could easily lead to patient identification. Recognizing these nuances helps organizations assess the risk associated with different data elements and implement appropriate security measures.
PHI Definition and Examples
Protected Health Information (PHI) refers explicitly to any data used within medical contexts that can identify patients. While PHI does not explicitly specify personally identifiable data, it encompasses information that, when combined with medical details, can reveal patient identities. The HIPAA Security Rule governs the handling of such information, emphasizing strict confidentiality and security.
Typical examples of PHI include:
- Patient names
- Addresses
- Dates of birth
- Medical records
- Driver’s license numbers
- Credit card information
Because PHI is subject to rigorous legal protections, organizations must ensure its confidentiality and proper use. Unlike general PII, which may be protected under various regulations, PHI is under specific mandates to prevent unauthorized disclosures, making its safeguarding a legal obligation.
Developing a Unified Compliance Approach
The landscape of data privacy in the United States is characterized by a patchwork of industry-specific laws, state regulations, and international standards. For example, California’s strict PII laws can create compliance challenges for companies operating across state lines, especially when data is shared or accessed in different jurisdictions. A breach in one state could inadvertently violate another’s stricter standards.
While PHI requirements are particularly stringent under HIPAA, broader regulations such as PCI DSS, GLBA, and GDPR demand comprehensive data protection practices. Rather than creating separate compliance frameworks for each regulation, organizations should adopt universal encryption and security best practices that address PII and PHI alike. This approach simplifies compliance and reduces the risk of violations.
PII and PHI Security Across Industries
Effective security begins with identifying where PII resides—whether in electronic health records, email communications, backups, or third-party vendor systems. Once identified, organizations should evaluate the potential impact of a breach using the confidentiality impact level outlined in standards like NIST SP 800-122. This involves considering several factors:
- Identifiability: How easily can the individual be recognized?
- Quantity of PII: How many identities could be compromised? Larger datasets, such as those in clinics or onboarding systems, pose greater risks.
- Data Sensitivity: Are the data fields highly sensitive? For example, social security numbers or credit card details carry more risk than phone numbers.
- Context of Use: Does the manner in which the data is used or shared affect its sensitivity? A newsletter list differs significantly from patient medical records.
- Legal Obligations: What regulations govern the data? Healthcare organizations must adhere to HIPAA, while financial institutions must comply with PCI or GLBA.
- Storage and Access: Is the data stored securely, and how is it accessed? Data stored offsite or accessed by third parties introduces additional risks.

For example, organizations involved in training the surgeons of tomorrow with virtual reality are leveraging immersive tech to improve skills while maintaining compliance standards.
Implementing PII Security Best Practices
Reducing data vulnerability starts with collecting only what is necessary and removing unnecessary PII from records. De-identification techniques, such as anonymization and tokenization, can effectively remove PII from datasets, often rendering them outside the scope of HIPAA regulations.
Access control is equally vital; sensitive data should only be accessible to staff with a legitimate need. For example, administrative staff involved in billing should not have access to detailed medical records. Encryption should be the default security measure for all sensitive information, whether stored in cloud environments or transmitted via email.
However, securing patient communication remains challenging, especially with the low adoption of healthcare portals. Here, solutions like Virtru’s email encryption enable patients to securely receive and reply to messages using familiar email platforms, significantly reducing friction and enhancing compliance.
How to Automate PHI and PII Security for HIPAA
Automation simplifies the enforcement of data security policies and reduces human error. Virtru provides tools that automatically detect sensitive keywords in outgoing emails, alert users, or encrypt messages before they are sent. For example, administrators can define specific terms or data formats (such as social security numbers) to trigger warnings or encryption, ensuring sensitive information is protected in real-time.
Revoke capabilities further enhance security by allowing organizations to withdraw access to sent emails or files if sent in error. This is particularly important in healthcare, where accidental disclosures can have serious consequences. As Jason Karn, Chief Compliance Officer at Total HIPAA, notes, “Having the ability to deny access to PHI after sending it can prevent breaches and limit damage.”
Integration with customer relationship management (CRM) systems, like Zendesk or Salesforce, enables secure communication with patients and clients. This ensures sensitive data remains protected throughout its lifecycle, from initial collection to ongoing interactions. For instance, Bennie uses Virtru to ensure HIPAA-compliant exchanges in their support workflows.
HIPAA Business Associates (BAAs)
HIPAA imposes additional responsibilities on organizations working with third-party vendors or partners that handle PHI, known as business associates. These entities must sign Business Associate Agreements (BAAs) outlining their obligations regarding data use, security measures, breach response, and notification procedures. Selecting reliable business associates and conducting regular audits ensures compliance and minimizes liability.
HIPAA Notices and Notifications
Organizations must provide patients with a notice of privacy practices, describing how their data is used, their rights, and the organization’s responsibilities. In case of a data breach, HIPAA mandates notification within 60 days. Encrypting data effectively can help organizations avoid breach notifications altogether, as encrypted data is generally exempt from breach reporting unless the encryption key is compromised. Adopting comprehensive PII security protocols simplifies compliance and enhances patient trust.
Following these best practices makes HIPAA compliance more manageable and ensures that sensitive patient information remains protected. By integrating security measures across all organizational levels, healthcare providers can deliver high-quality care while maintaining the highest standards of confidentiality.
