ERISA vs PHSA Health Plan Compliance
ERISA vs PHSA health plan compliance is one of the most common—and most misunderstood—regulatory challenges facing today’s employer-sponsored health plans. Whether you manage benefits for a private employer with a large workforce or a public entity such as a university serving thousands of students and staff, federal regulations increasingly shape how health plans must operate.
For many sponsors, mastering payment integrity and fiduciary compliance is foundational to reducing risk and protecting plan assets—a capability outlined in ClaimInformatics’ overview of its payment integrity solutions.🔗 Learn more
Unexpected medical bills, expanding transparency requirements, and mounting compliance deadlines often leave plan sponsors asking a critical question: Which rules actually apply to my plan? The answer depends largely on whether the plan is governed by the Employee Retirement Income Security Act (ERISA) or the Public Health Service Act (PHSA)—two cornerstone laws with materially different implications for oversight, accountability, and risk.
Which Organizations Are Governed by ERISA vs PHSA?
The distinction between ERISA and PHSA begins with who sponsors the health plan.
ERISA governs most privately sponsored health plans, including those offered by private employers, unions, and non-profit organizations. These plans are subject to strict fiduciary standards, reporting obligations, and enforcement mechanisms, primarily overseen by the U.S. Department of Labor.
The Public Health Service Act of 1944 (PHSA), by contrast, governs publicly sponsored health plans. This includes plans operated by state and local governments, public universities, school districts, municipalities, and the federal government. While PHSA plans are exempt from ERISA fiduciary requirements, they remain subject to many federal healthcare mandates—particularly those introduced through the Affordable Care Act (ACA), the Consolidated Appropriations Act (CAA), and the No Surprises Act (NSA).
What Is the Difference Between ERISA and PHSA for Health Plans?
The Employee Retirement Income Security Act of 1974 (ERISA) governs privately sponsored health plans and establishes standards for fiduciary responsibility, reporting, disclosure, and participant rights. These requirements are designed to ensure plans are managed prudently and in the best interests of participants.
The Public Health Service Act of 1944 (PHSA) governs publicly funded health plans sponsored by governmental entities. While both ERISA and PHSA aim to protect health plan participants, PHSA does not impose the same fiduciary liability framework found under ERISA—creating meaningful differences in oversight, enforcement, and accountability.
Fiduciary compliance is not just a checkbox—it is a pathway to smarter, more efficient healthcare management.
Why ERISA vs PHSA Compliance Matters for Plan Fiduciaries
Understanding ERISA vs PHSA health plan compliance is not just a regulatory exercise—it directly impacts fiduciary responsibility, claims administration, and financial oversight. Employers that misapply these rules risk noncompliance, increased healthcare costs, and, in some cases, legal exposure tied to claims processing and benefit administration.

For private employers, ERISA vs PHSA health plan compliance is especially critical because ERISA imposes fiduciary duties that extend into claims payment accuracy, vendor oversight, and cost-control strategies.
ERISA vs PHSA: Side-by-Side Health Plan Compliance Requirements
The distinction between ERISA and PHSA becomes especially important when evaluating which compliance obligations apply to public-sector versus private-sector employers. ERISA vs PHSA health plan compliance determines not only which federal standards govern a plan, but also how accountability, enforcement, and oversight are applied across claims and vendor relationships.
Key Compliance Gaps and Overlaps Between ERISA and PHSA
Most provisions mirror each other, reflecting a push for uniform protection across plan types. Both ERISA and PHSA require the removal of “gag clauses” that once restricted transparency into healthcare costs and quality. Advance Explanation of Benefits (EOB) requirements help participants understand costs before care is delivered, reducing surprise billing.
ERISA plans include an additional fiduciary safeguard through Section 408(b)(2) disclosures, which require detailed fee transparency from service providers. These disclosures do not apply to PHSA plans, creating differences in fiduciary oversight and cost governance.
This distinction underscores the importance of independent payment integrity review, a theme explored in ClaimInformatics’ analysis of how unbiased review restores fiduciary trust and reduces waste. 🔗 Detailed article
ERISA vs PHSA: What the Differences Mean for Plan Sponsors and Members
ERISA’s fiduciary framework imposes a higher standard of accountability on private plan sponsors, requiring decisions to be made solely in the best interests of participants. While this increases responsibility, it also encourages innovation in cost control, vendor management, and data-driven oversight.
PHSA plans, commonly sponsored by government entities, prioritize public health equity but do not impose ERISA’s fiduciary disclosure requirements. As healthcare delivery evolves through telehealth, artificial intelligence, and value-based care models, this difference can create oversight challenges if claims accuracy and compliance are not actively monitored.

Frequently Asked Questions: ERISA vs PHSA for Public and Private Employers
How do ERISA fiduciary rules affect private employers?
Private employers that sponsor self-funded or fully insured health plans are typically governed by ERISA and are subject to strict fiduciary responsibilities. These obligations require plan sponsors and administrators to act prudently, manage plan assets responsibly, and ensure claims are paid accurately and in the best interests of participants.
From a practical standpoint, fiduciary responsibility extends beyond plan design. Claims payment accuracy, vendor oversight, pharmacy benefit management, and compliance with transparency requirements all fall within the fiduciary’s scope. Failure to identify overpayments, improper billing, or noncompliant practices can expose employers to fiduciary breach claims, regulatory penalties, and litigation risk.
How are public-sector employers regulated under PHSA?
Public-sector employers—including state and local governments, public universities, school districts, and other governmental entities—are exempt from ERISA and regulated under the Public Health Service Act (PHSA).
While PHSA plans are not subject to ERISA’s fiduciary liability framework, they must comply with many federal mandates introduced under the ACA and CAA, including cost transparency, continuity of care protections, and limits on balance billing.
How does the No Surprises Act impact both public and private employers?
The No Surprises Act (NSA) applies broadly across both ERISA- and PHSA-governed plans. It protects participants from unexpected out-of-network bills, requires accurate provider directories, and mandates timely, transparent explanations of benefits.
