Understanding the distinctions between Protected Health Information (PHI) and Personally Identifiable Information (PII) is vital for healthcare organizations aiming to stay compliant with HIPAA regulations while leveraging data for marketing and operational improvements. Both types of data are sensitive, but their handling, legal implications, and the ways they influence compliance efforts vary significantly. This article explores how these data categories impact your ability to adhere to HIPAA, protect patient privacy, and execute compliant marketing strategies.
In today’s digital health landscape, organizations must carefully manage sensitive information to avoid hefty penalties and uphold patient trust. As analytics and marketing tools become more integrated into healthcare operations, understanding the nuances of PHI and PII becomes even more critical. This guide delves into their definitions, differences, legal consequences, and best practices to safeguard data and ensure compliance.
PHI vs PII
Defining PII
Personally Identifiable Information (PII) refers to any data that can be used to identify or link to an individual. Its scope varies depending on legal, regulatory, or industry contexts but generally includes details such as full name, home address, email, social security number, passport or driver’s license numbers, and financial information like credit card details. It also encompasses digital identifiers like IP addresses, device IDs, cookies, and other online tracking data.
In the United States, agencies such as the National Institute of Standards and Technology (NIST) provide guidelines on PII, emphasizing the need for case-by-case assessments to determine risk levels associated with different data types. Despite ongoing discussions about comprehensive federal data privacy laws, a unified legislation protecting PII across all states remains elusive. Some states, including Delaware, Iowa, Maryland, and Tennessee, are enacting laws to bolster data privacy protections starting in 2025.
The broad scope of PII also covers medical, educational, employment, and financial records, making it a versatile but complex category. A key aspect of PII is the potential risk posed if this data is mishandled or leaked, which can lead to identity theft, fraud, or privacy violations.
What Constitutes PHI in Healthcare?
Protected Health Information (PHI) is a subset of PII that specifically pertains to health-related data processed by HIPAA-covered entities. It includes any information that can identify an individual and is related to their health status, healthcare provision, or payment for healthcare services. Examples include a patient’s name, address, date of birth, social security number, biometric data, lab results, medical history, and even certain device identifiers.
The Department of Health and Human Services (HHS) enumerates 18 specific identifiers that, when combined with health information, qualify the data as PHI. These include geographic details, dates related to healthcare, contact information, medical record numbers, and biometric identifiers. Notably, data like phone numbers or addresses alone do not constitute PHI unless they are linked to health information, such as a diagnosis or treatment details.
The classification of PHI is subject to legal standards, and healthcare providers, insurers, and other covered entities must rigorously safeguard this data. For example, even website visits or app interactions that include health-related content can be considered PHI if they involve identifiable information, which has led to ongoing legal debates and regulatory clarifications.
For more details on what qualifies as PHI, visit the HIPAA journal. The recent legal case involving the American Hospital Association (AHA) challenged the expansion of PHI to include IP addresses tied to health content, highlighting the complexity of defining protected health data in digital contexts.
Legal Implications and Penalties
HIPAA enforces strict rules that govern the handling of PHI, with significant penalties for violations. Non-compliance can lead to substantial fines—up to $25,000 per violation category annually—and, in severe cases, criminal charges including incarceration. Healthcare entities must notify authorities and affected individuals within specified timeframes, typically 60 days for breaches involving PHI, and follow strict security protocols established by the HIPAA Security Rule.
In contrast, violations involving PII outside the healthcare context are governed by a patchwork of state and federal laws, such as breach notification statutes. These laws require organizations to inform impacted individuals and authorities promptly, with fines and penalties varying by jurisdiction.
To effectively protect PHI and avoid penalties, healthcare organizations should establish comprehensive safeguards, including administrative policies, physical security measures, and technical controls like encryption and access management. Working with vendors that support privacy by design—integrating data privacy considerations into system development—is also essential.

Penalties for Non-Compliance
The consequences of mishandling PII and PHI are starkly different but equally severe. For PII, violations can result in fines up to $5,000 per incident and potential incarceration if the disclosure is intentional. The National Institute of Standards and Technology (NIST) categorizes PII according to risk levels, helping organizations prioritize protective measures based on data sensitivity.
HIPAA-specific violations related to PHI are governed by four penalty tiers, ranging from $100 to $25,000 per violation, depending on the level of negligence and intent. Healthcare providers and business associates must implement rigorous security measures, conduct regular risk assessments, and ensure breach notification procedures are in place to mitigate legal risks.

Protecting PHI in Analytics and Marketing
As healthcare organizations increasingly use analytics tools to improve patient care and operational efficiency, safeguarding PHI becomes more challenging. To stay compliant, organizations should establish a business associate agreement (BAA) with any platform or vendor handling PHI, ensuring they adhere to HIPAA standards. When sharing PHI with third parties, de-identification techniques—such as Expert Determination or Safe Harbor—are essential to remove all identifiers and render data non-protected.
Implementing the HIPAA Security Rule’s safeguards is critical. This includes:
- Administrative safeguards: ongoing risk analyses, workforce training, and incident response plans.
- Physical safeguards: securing physical access to servers and data storage facilities.
- Technical safeguards: encryption, access controls, audit logs, and secure transmission protocols.
Employing privacy-by-design principles and choosing vendors committed to data privacy enhance security. When vendor relationships cannot include a BAA, de-identifying data for research or marketing purposes becomes an effective alternative.

HIPAA-Compliant Marketing Strategies
Marketing within healthcare must strictly adhere to HIPAA’s privacy regulations. Using PHI in marketing campaigns requires explicit, informed patient consent obtained through signed authorization forms. Data collection from marketing pages must avoid including identifiers that could constitute PHI unless properly authorized.
Most standard analytics tools, including Google Analytics 4, do not support HIPAA compliance because they lack BAAs and are not designed to handle protected health data. Transitioning to HIPAA-compliant analytics platforms—such as Piwik PRO Analytics Suite—ensures secure data handling, including the management of user IDs, IP addresses, and other identifiers used in retargeting or personalization efforts.
To build a secure data ecosystem, consider utilizing a customer data platform (CDP) that supports HIPAA-compliant practices. Implementing consent management tools and role-based access controls further reduces risk. Regular monitoring, transparent communication with patients about data use, and adherence to HIPAA rules are fundamental to responsible healthcare marketing.

Final Thoughts
Maintaining HIPAA compliance while leveraging PII and PHI requires a comprehensive understanding of legal standards, technical safeguards, and ethical data management. Healthcare providers should prioritize privacy-first data strategies, including using HIPAA-certified analytics solutions and de-identification techniques, to foster patient trust and avoid costly violations.
Relying on HIPAA-compliant platforms rather than general-purpose ad or analytics tools reduces the risk of breaches and fines. Developing a first-party data approach, centered on patient consent and privacy, will strengthen your organization’s reputation and support compliant marketing efforts.
