ERISA Fiduciary Duty: What Self-Funded Plan Sponsors Must Know

The Fiduciary Standard Is Rising

The Department of Labor has significantly increased enforcement of ERISA fiduciary obligations for self-funded health plan sponsors. Recent settlements and advisory opinions signal that "we trusted our broker" is no longer an adequate defense.

Core Fiduciary Obligations

Under ERISA Section 404, plan fiduciaries must:

• Act solely in the interest of plan participants and beneficiaries
• Act with the care, skill, prudence, and diligence that a prudent person would use
• Ensure plan expenses are reasonable
• Follow the plan documents to the extent consistent with ERISA

Where Employers Fall Short

Vendor Fee Oversight

Many employers have never benchmarked their TPA, PBM, or stop-loss fees against market standards. Paying above-market fees without documentation of a prudent selection process is a fiduciary breach.

Broker Compensation Transparency

The Consolidated Appropriations Act (CAA) now requires disclosure of broker and consultant compensation. But disclosure alone isnt enough — fiduciaries must evaluate whether that compensation is reasonable for services received.

Data-Driven Decision Making

Approving renewals or plan changes without independent claims analysis is increasingly viewed as imprudent. Fiduciaries should be able to demonstrate that decisions were informed by objective data, not just vendor presentations.

Building a Fiduciary Defense

The strongest fiduciary defense is a documented, independent review process. This means engaging independent analysts — not affiliated with your broker, carrier, or vendors — to validate pricing, performance, and plan design decisions annually.
