What is a plan sponsor under HIPAA?

Employees often assume that any health information connected to workplace benefits is visible to their employer, but HIPAA draws a much sharper line. The employer as an employer is different from the group health plan as a HIPAA-regulated health plan. A group health plan is generally a covered entity, while employers and other group health plan sponsors are not covered entities simply because they sponsor the plan.

The distinction matters because employee health plan data can be useful to employers but is also sensitive. A 2023 Population Health Management scoping review found that “Employers may evaluate employee claims data” for reasons such as assessing plan performance, monitoring workforce health trends, and identifying wellness priorities. It also found that 59% of the reviewed studies supplemented claims data with other sources, such as human resources data.

What is a plan sponsor under HIPAA?

A plan sponsor is the employer, union, association, or organization that establishes and maintains a group health plan. Simply put, it is the body underneath the employee health benefit. It may fund the plan, choose vendors, negotiate coverage, and assist with plan administration. The point is that sponsoring the plan does not give the employer open access to employee health information.

HIPAA treats health plan information as sensitive because, as one NCBI Bookshelf chapter explains, “Medical records, which often contain personal and sensitive information, seem particularly vulnerable.” The risk becomes more practical in modern benefits administration as health information often flows through email, vendors, portals, claims systems, and internal workflows. In 2025, there were 170 healthcare email-related breaches, exposing the protected health information of 2.5 million people and underscoring the need for plan sponsor access to be narrow, documented, and controlled, according to Paubox’s 2026 Healthcare Email Security Report.

Is a plan sponsor a HIPAA covered entity?

The HHS is clear that “Neither employers nor other group health plan sponsors are defined as covered entities under HIPAA.” Typically, the covered entity is the group health plan, not the employer sponsoring the plan. The group health plan is considered separate from the employer or other entity that sponsors it, HHS also notes.

HIPAA directly regulates the group health plan and then controls when and how the plan may share protected health information with the plan sponsor. StatPearl’s HIPAA overview explains the larger purpose well, HIPAA regulations “uphold patients’ rights to confidentiality and empower them to control the disclosure of their health information.”

The distinction between employer records and health plan records

The employer’s HR function is responsible for the employment records, and the health plan records are the group health plan. In another section, the HHS explains that “The Privacy Rule does not protect your employment records, even if the information in those records is health-related. In most cases, the Privacy Rule does not apply to the actions of an employer.” For example, if an HR department keeps a doctor's note for sick leave, that may be an employment record, not a HIPAA health plan record. A group health plan keeps a claim file, diagnosis, prescription record, treatment record, or benefits appeal.

The line also depends on people knowing when something has gone wrong. According to Paubox, in their 2026 report, employees reported only 4% of known HIPAA email violations. The HHS notes that the Privacy Rule does protect medical or health plan records when the person is a patient of the provider or a member of the health plan.

When can a group health plan share PHI with a plan sponsor?

A group health plan may share protected health information with a plan sponsor only for plan administration functions and only when HIPAA’s conditions are met. The plan documents must restrict the sponsor’s use and disclosure of that information, and the plan sponsor must certify that it will protect the information and not use it for employment-related decisions.

HIPAA also allows limited sharing of summary health information for purposes such as obtaining premium bids or modifying, amending, or terminating the group health plan. It also permits sharing basic enrollment or disenrollment information. The key is purpose limitation: the sponsor may receive what it needs to administer the plan, not what it wants for HR, productivity, discipline, hiring, or promotion decisions.

An Institute of Medicine (US) Committee on Health Research and the Privacy of Health Information chapter on health information privacy explains the principle well: “Privacy addresses the question of who has access to personal information and under what conditions.” It also notes that privacy asks whether data collected for one purpose can be used for another purpose, which is exactly why HIPAA limits plan sponsor access to plan administration rather than broader employer use.

What safeguards must be in place?

HIPAA requires a firewall between the group health plan and the plan sponsor. The plan documents must describe the employees or classes of employees who may have access to protected health information, restrict such access to plan administration functions, and establish a process for resolving noncompliance. The plan sponsor shall agree not to use or disclose the information except as permitted by the plan documents, shall ensure that agents agree to the same restrictions, shall report any improper use or disclosure, and shall return or destroy information when it is no longer needed, where feasible.

StatPearl’s patient confidentiality guidance states that “Ensuring the security, privacy, and protection of patients’ healthcare data is critical,” especially in an era of fast-moving health technology. The Change Healthcare incident shows why those safeguards cannot be treated as paperwork. As Paubox reports in a 2025 article, Change Healthcare notified the Office for Civil Rights on July 31, 2025, that approximately 192.7 million individuals had been impacted, making the incident a clear example of how administrative, vendor, and claims-related systems can expose health information on an enormous scale when controls fail.

Plan sponsors should have a practical safeguard in place that includes role-based access, minimum necessary use, audit logs, vendor controls, employee training, incident reporting, and a documented separation of HR decisions and health plan administration. Paubox helps healthcare organizations secure email workflows, decrease unnecessary exposure of protected health information and improve day-to-day communication without adding unnecessary friction for authorized users, supporting that control environment.
