Which Data Is Classified as Protected Health Information (PHI)?

When managing employee benefits and health coverage, employers handle sensitive information that requires careful protection. Understanding what is protected health information PHI helps organizations maintain compliance while serving their employees effectively. This knowledge becomes especially important as more companies adopt health reimbursement arrangements and other benefits that involve health-related data.

Protected Health Information Definition

The protected health information definition comes directly from the Health Insurance Portability and Accountability Act, commonly known as HIPAA. According to the HHS Summary of the HIPAA Privacy Rule, protected health information encompasses all "individually identifiable health information" held or transmitted by a covered entity or its business associate, in any form or media, whether electronic, paper, or oral.

This means PHI isn't limited to digital records. Paper documents containing patient information, verbal discussions about someone's health condition, and electronic files all fall under HIPAA protections when they meet the criteria for individually identifiable health information.

What Is Considered Protected Health Information?

Understanding what is considered protected health information requires examining two components: the type of information and its connection to an identifiable individual.

Health-Related Information Categories

Information qualifies as health-related when it pertains to an individual's past, present, or future physical or mental health condition, the provision of healthcare to the individual, or the past, present, or future payment for healthcare services. This broad scope covers medical records, treatment histories, prescription information, billing records, and insurance documentation.

The Identification Connection

Health information becomes "protected" when it includes identifiers that link the data to a specific person. A blood pressure reading by itself isn't PHI. However, that same reading attached to a patient name, medical record number, or other identifier becomes protected health information subject to HIPAA requirements.

The 18 HIPAA Identifiers

HIPAA specifies 18 types of identifiers that, when combined with health information, create protected health information. Small business owners and benefits administrators should recognize these categories.

Direct Identifiers

The most obvious identifiers include names, Social Security numbers, telephone numbers, email addresses, and physical addresses. When any of these appear alongside health information, that data requires protection under HIPAA rules.

Dates and Numbers

Birth dates, admission dates, discharge dates, and dates of death qualify as identifiers when associated with health information. Medical record numbers, health plan beneficiary numbers, account numbers, and certificate or license numbers also fall into this category.

Digital and Biometric Identifiers

In today's connected world, digital identifiers matter significantly. Internet Protocol addresses, device identifiers, web URLs, and biometric identifiers like fingerprints and voiceprints can all link health information to specific individuals. Vehicle identifiers, license plate numbers, and full-face photographs or comparable images also qualify.

Any Other Unique Identifying Number

HIPAA includes a catch-all category covering any other unique identifying number, characteristic, or code that could reasonably be used to identify an individual. This ensures emerging identification methods receive appropriate protection.

What Is Classified as Protected Health Information in Practice?

Seeing what is classified as protected health information through practical examples helps clarify the concept.

Examples of PHI

Common examples include medical records containing patient names, insurance claim forms with member identification numbers, prescription labels with patient addresses, appointment schedules showing patient names and visit reasons, lab results linked to identifying information, and billing statements that reference specific healthcare services.

For enterprise organizations managing employee benefits, PHI might appear in enrollment forms, claims data, and communications between employees and health plans.

What Doesn't Qualify as PHI

Health information stripped of all 18 identifiers is no longer considered protected health information. Aggregate health statistics that cannot be traced to individuals, de-identified research data meeting HIPAA standards, and general health education materials don't require the same protections.

Employment records held by a covered entity in its role as employer, rather than as a healthcare provider or health plan, generally fall outside HIPAA's scope. However, other privacy laws may still apply to this information.

Who Must Protect PHI?

HIPAA's Privacy Rule applies to specific categories of organizations known as covered entities.

Healthcare Providers

Doctors, hospitals, clinics, pharmacies, and other healthcare providers who transmit health information electronically in connection with certain transactions must comply with HIPAA requirements.

Health Plans

Health insurance companies, HMOs, employer-sponsored health plans, and government programs like Medicare and Medicaid qualify as covered entities. This includes organizations administering health reimbursement arrangements and similar benefits.

Healthcare Clearinghouses

Entities that process health information from one format to another on behalf of other organizations fall under HIPAA's requirements.

Business Associates

Organizations that perform functions or activities on behalf of covered entities involving PHI access must also protect this information. Brokers and benefits administrators often operate as business associates.

PHI Protection Requirements

Organizations handling protected health information must implement safeguards across three areas.

Administrative Safeguards

These include policies and procedures governing PHI use and disclosure, workforce training on privacy practices, and designation of a privacy officer responsible for compliance. Organizations must also conduct risk assessments and maintain documentation of their privacy practices.

Physical Safeguards

Protecting the physical spaces where PHI exists matters equally. This involves controlling access to facilities, securing workstations, and implementing policies for device and media disposal.

Technical Safeguards

Electronic PHI requires access controls, audit controls, integrity controls, and transmission security measures. Encryption, unique user identification, and automatic logoff procedures help protect digital health information.

How PHI Affects Benefits Administration

Startups and growing companies offering health benefits encounter PHI in several contexts.

Enrollment Processes

When employees enroll in health coverage, they provide information that may become PHI once combined with health plan participation details. Benefits administrators must handle this data appropriately.

Claims and Reimbursements

Health reimbursement arrangements involve reviewing expense documentation that often contains protected health information. Organizations need processes that protect employee privacy while administering these benefits effectively.

Communication with Carriers

Coordinating between employers, employees, and insurance carriers requires careful attention to PHI disclosure rules. Only the minimum necessary information should be shared for specific purposes.
