What Is a Self-Funded Health Plan?
Most of us get health insurance through our job. Usually, the company pays a health insurance company (like Blue Cross or Aetna), and that insurance company pays the doctor bills.
But some companies, especially big ones, do something different. Instead of paying an insurance company, they pay doctor bills directly from their own money. This is called a self-funded health plan.
When a company self-funds its health plan, it gets more control over how the money is spent. But it also takes on a big responsibility of making sure the plan is run fairly and follows the rules.
What Does Fiduciary Mean?
A fiduciary is someone who is trusted to take care of something that belongs to other people. Their job is to always act in the best interest of those people.
In a self-funded health plan, the company or individuals responsible for managing the plan may act as fiduciaries.
There is a law called ERISA that requires fiduciaries to follow strict standards. If those responsibilities are not met, fiduciaries may face legal and financial consequences, including personal liability in some cases.
What Are the Main Fiduciary Risks in Self-Funded Health Plans?
Fiduciary risk in self-funded health plans rarely arises from a single issue. Instead, it often develops across several areas that may receive greater attention once disputes or litigation arise.
Excessive or Unreasonable Fees
Failing to benchmark TPA, PBM, and stop-loss fees against the market invites claims that the fiduciary paid more than was reasonable for plan services.
Conflicts of Interest with Vendors
Undisclosed compensation arrangements between brokers, TPAs, and pharmacy benefit managers can constitute a prohibited transaction under ERISA Section 406.
Not Monitoring Claims Administration
If an employee claim is denied incorrectly, the company needs oversight into how claims are processed and resolved. Delegating claim administration to a service provider does not eliminate fiduciary obligations.
Prescription Drug Cost Failures
The CAA 2021 requires plans to demonstrate that prescription drug spending is reasonable. Failure to negotiate or benchmark drug costs is now a named liability.
Why Is This Receiving More Attention Now?
In 2021, the U.S. government passed the Consolidated Appropriations Act (CAA), which introduced new transparency requirements for employers and organizations that sponsor health plans.
The law extended disclosure requirements to health plan fiduciaries, similar to the fee disclosure rules that affected retirement plans.
One important requirement is compensation disclosure. Brokers and service providers that receive $1,000 or more in direct or indirect compensation must disclose that information to the plan sponsor.
According to KFF's health policy research, employer plan fiduciaries who do not obtain these disclosures may face ERISA compliance concerns. Companies are expected to review and understand this information rather than simply collecting it.
How Can Companies Reduce Fiduciary Risk?
The courts have been consistent on one point: a fiduciary who can demonstrate a prudent, documented process is far more likely to prevail than one who cannot, even when the underlying decision was imperfect.
Courts mostly look at whether the company followed a smart, thoughtful process. Here is what that looks like:
- Create a benefits committee with clear responsibilities, defined members, and regular meetings, ideally at least once every quarter.
- Review TPA, PBM, and stop-loss providers every year by comparing costs, services, and options. Keep records showing why each vendor was selected.
- Collect and review compensation disclosures required under the CAA from brokers and consultants before renewing contracts.
- Review health plan data every quarter, including claim denials, appeals, and high-cost claims, instead of relying completely on the TPA.
- Consider fiduciary liability insurance that matches the size and spending level of the health plan.
Why PBMs Need Extra Attention
PBMs (Pharmacy Benefit Managers) manage prescription drug benefits in self-funded health plans. Because prescription drugs are often one of the largest plan expenses, PBM decisions can have a major effect on costs and employee access to medications.
PBMs may earn money in different ways, and those arrangements are not always easy to understand. This can make it harder for companies to know whether they are getting fair pricing and value.
For this reason, PBM relationships have become an important area of focus in self-funded health plans and fiduciary oversight.
Hiring Vendors Does Not Transfer Responsibility
Many companies believe that hiring a TPA, PBM, or benefits broker transfers responsibility for the health plan. In reality, companies still have fiduciary responsibilities.
Even when outside vendors handle daily tasks, the company is still expected to oversee the plan and monitor how those services are being provided.
The Bottom Line
Self-funding a health plan means more control but also more responsibility. ERISA holds plan managers to a high standard, and the rules around fees, vendors, and transparency are only getting stricter.
The companies that stay out of trouble are not necessarily the ones that get every decision right. They are the ones that pay attention, ask questions, and write it all down. SHRM's health care cost management toolkit is a practical starting point for employers who want to build that process.
Fiduciary risk is real, and it grows when it is ignored. The best time to take it seriously is before a problem appears.
