When employers offer group health benefits, they also take on fiduciary responsibilities that shape every aspect of how the plan is managed and how participants are served. With ongoing regulatory changes related to transparency, mental health requirements, claims processing and cost containment, understanding fiduciary duties is more important today than ever.
ERISA, the Employee Retirement Income Security Act, outlines the standards that fiduciaries must follow. These rules apply to most employer sponsored group health plans, whether they are fully insured, self-funded or a combination of both. ERISA sets clear expectations for how plans operate and how plan assets must be handled.
What Defines an ERISA Covered Group Health Plan
The Department of Labor defines an ERISA covered group health plan as an employment-based plan that provides medical care coverage. This includes hospitalization, physician services, prescription drugs, mental health and substance use treatment, dental and vision benefits. Plans may provide these benefits through insurance, a trust or by paying claims directly from the employer’s general assets.
Core Components of a Compliant Plan
Every ERISA covered plan must include several foundational elements. These include a written plan document that outlines benefits and administrative procedures, a trust to hold plan assets when applicable, a recordkeeping system that tracks contributions and claims and required disclosures that keep participants informed. These components support transparency, accuracy and accountability.
Who Is Considered a Fiduciary
Under ERISA, fiduciary status is determined by actions rather than job title. An individual is considered a fiduciary when they have discretionary authority or control over how a benefit plan is managed, operated, or administered, or when they exercise authority over plan assets. This determination depends on the nature of the decisions being made, not on formal role descriptions.
Fiduciary responsibilities carry a high standard of care, and as regulatory expectations continue to evolve, staying informed is essential to protecting both the plan and its participants.
Ultimately, the defining factor is decision making authority. Anyone with the ability to influence how a plan operates or how benefits are delivered should understand that fiduciary responsibilities may apply to their actions and ensure appropriate oversight and processes are in place.
Key Fiduciary Responsibilities
Fiduciaries must act solely in the interest of participants, follow plan documents, carry out duties prudently, ensure plan assets are protected and pay only reasonable plan expenses. These responsibilities require consistent oversight, careful documentation and a strong understanding of regulatory requirements. Failure to meet fiduciary standards can result in personal liability for losses to the plan.
