Receiving a reimbursement demand from a self-funded ERISA plan's third-party subrogation administrator is a routine experience in personal injury practice. The demand is often presented as non-negotiable, citing the plan's summary plan description (SPD) and its right to full reimbursement from any tort recovery. What the letter typically does not tell you is that the plan's right is constrained by federal case law, by the sufficiency of the plan documents themselves, and by the timing of your disbursement. Understanding the limits is the difference between giving the plan a dollar-for-dollar recovery and negotiating it to a fraction of the demand.
The Reimbursement Right: What Sereboff Confirmed
In Sereboff v. Mid Atlantic Medical Services, Inc. (2006), the Supreme Court confirmed that an ERISA self-funded plan can seek reimbursement from the tort recovery under ERISA Section 502(a)(3) as equitable relief if the plan document creates an equitable lien by agreement on a specifically identified fund. The Court held that an ERISA plan could enforce a constructive trust over the specifically identifiable tort settlement proceeds because those proceeds were the very fund that the plan had agreed to share in under the plan documents. Sereboff is the foundational authority for the plan's reimbursement claim.
The limitation Sereboff imposes is equally important: the lien must attach to a specifically identified fund, and the plan must trace its claim to that fund. A plan that can only identify an amount paid in medical benefits, without identifying a specific segregated recovery fund, has a more difficult enforcement posture.
The Montanile Defense: Act Before You Disburse
Montanile v. Board of Trustees of the National Elevator Industry Health Benefit Plan (2016) is the most important ERISA reimbursement decision for plaintiff counsel because it created a procedural defense based on disbursement timing. The Supreme Court held that once the plaintiff has dissipated the tort settlement proceeds by spending or commingling them with general assets, the plan loses its equitable lien enforcement right. The equitable remedy under 502(a)(3) is available only against the specific, identifiable fund, not against general assets.
The practical implication for plaintiff practitioners: if your client receives a reimbursement demand after the settlement has already been disbursed and the proceeds have been spent or commingled with the client's personal accounts, the plan's equitable lien may be unenforceable as a matter of federal law. Document the disbursement and the subsequent use of funds carefully. Do not treat the Montanile defense as a way to engineer dissipation to avoid the lien, which courts will treat as bad faith. But where disbursement has already occurred before the plan's demand arrived or before the plan secured any enforcement action, raise Montanile as a threshold defense.
Does the Made-Whole Doctrine Apply to ERISA Plans?
State law made-whole rules, which prevent an insurer from seeking reimbursement until the injured party has been fully compensated for all losses, do not apply to self-funded ERISA plans. ERISA preempts state anti-lien and anti-subrogation laws under Section 514(a). The Eighth Circuit's decision in Administrative Committee of Wal-Mart Associates' Health and Welfare Plan v. Varco and subsequent circuit decisions have made clear that state law equitable doctrines designed to protect tort plaintiffs from plan reimbursement are preempted.
However, whether a federal common law made-whole doctrine applies to ERISA plans is genuinely contested among the circuits. The Fifth and Eighth Circuits have rejected a federal made-whole doctrine. The Ninth Circuit has been more receptive to plan-specific arguments. If your case is in a circuit that has not definitively resolved the question, preserve the argument and cite the circuit split. More importantly, check whether the plan documents themselves contain a made-whole provision. Some plans, particularly those administered by carriers that also write individual health policies, have incorporated made-whole language into the SPD or the plan document. Where the plan's own documents condition reimbursement on the plaintiff being made whole, that contractual provision is enforceable even in ERISA cases.
Plan Document Defects That Limit Recovery
The plan's reimbursement right is only as strong as its documents. Before conceding the plan's right to recovery, request and review the full plan document and the SPD. Common defects that reduce or eliminate recovery include:
- The plan document creates a subrogation right (step-into-the-plaintiff's-shoes to recover from the tortfeasor) but not a reimbursement right against the plaintiff's own recovery. Courts have held that subrogation rights and reimbursement rights are legally distinct, and a plan with only a subrogation clause may not be entitled to reach the plaintiff's tort proceeds.
- The reimbursement clause contains a made-whole condition that the administrator failed to apply before making the demand.
- The plan's right of first recovery is triggered only after the plan's subrogation claim against the tortfeasor has been fully exercised, and the plan skipped that step.
- The claims paid amount in the demand includes payments that are not covered under the plan document as medical expenses, such as administrative fees, stop-loss premium allocations, or payments for conditions unrelated to the tortious injury.
Request an itemized claims-paid breakdown with the corresponding explanation of benefits (EOB) for each claim included in the demand. Compare the items against the plan's covered benefits schedule and the medical records. Plans regularly include in their demand amounts paid for treatment of pre-existing conditions that are not causally related to the tort injury. Those amounts are not the proceeds of the tort claim and should not be counted in the reimbursement demand.
Negotiation Framework
Once you have identified the plan document defects and the appropriate claims-paid amount, the negotiation follows a familiar pattern in lien resolution practice. Present the plan with: (1) the total recovery, (2) the attorney's fees and costs charged against the fund, (3) the common fund doctrine argument that the plan should share in procurement costs, and (4) the applicable reimbursement ceiling after applying the plan's own terms and the Sereboff identification requirement. For plans that refuse to negotiate, the Montanile disbursement defense and the plan-document defect arguments give you leverage in a 502(a)(3) declaratory relief action.
