DOL Retreats From ERISA; Plaintiff Class Actions Fill the Gap

The DOL's April 2026 enforcement pivot narrows regulatory risk for employer health plans but transfers it intact to plaintiff class action counsel. Self-funded plan sponsors that relax fiduciary documentation in response are increasing, not decreasing, their expected ERISA litigation cost.

By Sam, EditorSeptember 2026 · 3 min read

On April 14, 2026, the Department of Labor’s Employee Benefits Security Administration issued Field Assistance Bulletin 2026-01, directing EBSA investigators to concentrate on “the most egregious conduct” and to stop second-guessing fiduciaries who followed a reasonable process, even if that process produced a suboptimal outcome for participants.

Trade press read it as an employer win. It is, as far as it goes. But the same quarter, plaintiff class action filings against employer-sponsored health plans were running at nearly double the prior year’s pace. Gibson Dunn’s Second Quarter 2026 ERISA Litigation Update, published August 31, 2026, puts the Q1 2026 filing count at approximately 70 actions, up from 38 in Q1 2025, an 84% year-over-year increase. The DOL stepped back; plaintiff counsel stepped forward. The aggregate contingent liability on employer-sponsored health plans did not shrink with the bulletin.

Who It Affects

Self-funded health plan sponsors at any enrollment size carry this exposure, but the concentration risk is highest among employers with more than 5,000 covered lives. Large enrollment amplifies the damages calculation in plan-design cases, where the theory produces a per-participant recovery multiplied across the entire class.

The most consequential theory visible in current filings is the “financially dominated plan” argument. In Barbich v. Northwestern University (N.D. Ill. 2026), a court allowed a participant challenge to proceed on the claim that the plan’s higher-premium PPO option delivered no proportionate clinical or financial benefit over lower-cost alternatives, making the decision to offer it a fiduciary breach. If offering a mathematically inferior option is itself a violation, any self-funded plan with multiple price tiers carries latent plan-design exposure. The earlier Caterpillar ERISA suit, covering more than 63,000 participants, ran the same theory and is still pending.

Tobacco surcharge plans are a separate exposure cluster. Gibson Dunn reports that more than a quarter of Q1 2026 health-plan filings involve surcharge programs challenged on ERISA grounds. Plan sponsors who adopted wellness surcharges without tying them to HIPAA-compliant alternatives face a distinct liability pocket outside the plan-design line.

TPAs also carry risk in both categories. A TPA that controls fund disbursement can be deemed a functional fiduciary, which affects indemnification structure and determines who fronts defense costs before any allocation between sponsor and administrator.

Reserve Mechanism

ERISA class action defense runs $3 million to $10 million through trial or settlement. At an 84% annual increase in filing rates, a large self-funded plan now carries a material expected value of being named as a defendant in any rolling 12-month window. That is a contingent liability, not a claims-development liability. It does not appear in the paid loss triangle, and standard IBNR methods do not detect it.

The Barbich damages model ties directly to enrollment size and the premium differential between competing options. A plan offering a $200 monthly gap between its lowest- and highest-cost tier across 10,000 lives carries a far larger exposure than its development triangle reveals, and that exposure is unrelated to whether any claim has been filed or paid.

What This Means for Your Next Review

The DOL bulletin reduces the risk of a government investigator challenging your plan’s decision-making process; it does not reduce the risk of a plaintiff challenging it. Courts, unlike EBSA, evaluate whether the process for selecting plan options was reasonable on its own terms, and Barbich suggests the bar is higher than most plan sponsors have been documenting to.

The ERISA fiduciary wave that took shape earlier this year has not receded under the new DOL posture. The enforcement vehicle changed. The fiduciary standard did not.

Ask your actuary whether the health plan analysis includes a contingent liability estimate for ERISA class action defense exposure. If not, ask what expected value a filing-rate-based estimate would produce at your enrollment size. Then ask your benefits counsel whether the documentation supporting each plan option you offer would satisfy the process standard Barbich appears to require.

Caterpillar ERISA Suit Extends Financial Dominance Theory

Three 2026 class actions, including Beyers v. Caterpillar covering 63,000-plus participants, argue that offering a mathematically inferior plan option violates ERISA fiduciary duty, creating a contingent employer liability that standard claims-based IBNR does not model.

Health Plan IDR Rulings Add $5B to Costs, Skewing IBNR Models

The No Surprises Act's arbitration process has added an estimated $5 billion to U.S. health system costs since 2022, with providers winning 88 percent of disputes; self-insured plan sponsors relying on pre-2022 paid triangles are systematically understating both expected claim ratios and development tails on recent accident years.

New Hampshire Sets Stop-Loss Floor at 110% of Expected Claims

New Hampshire's Bulletin INS 26-051-AB requires aggregate stop-loss attachment points for large employer groups at a minimum of 110% of actuarially supported expected claims, with annual carrier certification. The hidden risk is that a carrier using a below-market trend assumption satisfies the floor on paper while leaving the employer exposed in a silent corridor above the stated aggregate.
