Why ERISA matters to self-funded employers
The Employee Retirement Income Security Act (ERISA, 1974) is the federal law governing employer-sponsored benefit plans. For health benefits its most consequential feature is preemption: self-funded plans are regulated under the federal ERISA framework rather than state insurance law, which is why a self-funded employer can run one uniform plan design across every state it operates in, largely free of state benefit mandates and premium taxes.
That freedom is the legal foundation of self-funding's flexibility — and it comes bundled with responsibilities that fall on the employer as plan sponsor and, usually, plan fiduciary. (What follows is orientation, not legal advice; ERISA counsel earns its fee.)
The compliance basics every plan needs
The recurring obligations are documentary and procedural:
- Plan document & Summary Plan Description (SPD). The plan must be governed by a written document, and participants must receive an SPD in understandable language. A surprising number of self-funded plans run on a TPA's draft nobody has reconciled with what the plan actually does.
- Form 5500 annual filings for plans above the filing thresholds, plus Summary Annual Reports.
- Claims & appeals procedures meeting ERISA (and ACA) standards — deadlines, notices, external review.
- Required notices — SBCs, COBRA, HIPAA privacy, and the rest of the alphabet.
- Transparency-era additions. The Consolidated Appropriations Act layered on gag-clause attestations, broker/consultant compensation disclosure, and prescription-drug (RxDC) reporting — and it armed sponsors with the right to their own claims data. A TPA that resists sharing data is now a compliance problem, not just an annoyance.
Fiduciary duty is the part that's changing
ERISA fiduciaries must act solely in the interest of participants, with prudence, and must ensure the plan pays no more than reasonable costs. For decades that duty drew lawsuits mostly in the 401(k) world; the same theories have now arrived at health plans, with participants questioning whether sponsors prudently monitored PBM contracts, vendor fees, and plan spending.
Practically, the fiduciary era means a documented process: know what the plan pays (see claims data analysis), benchmark vendors periodically, scrutinize pharmacy benefit manager economics, and record the reasoning behind plan decisions. Nobody is required to make perfect choices — fiduciaries are required to make informed, documented, participant-first ones.
The same lens applies to benefit additions: a fiduciary-minded sponsor asks vendors for provable value. That's a bar a claims-reducing benefit should welcome — EZaccessMD is priced against avoided ER and urgent-care claims a sponsor can model in advance with the ROI calculator and then audit in its own data. The strategic context lives in the cost containment guide.
