ERISA subrogation dominates the conversation in PI lien resolution because self-funded employer health plans assert strong contractual reimbursement rights under federal law, and ERISA preempts the state-law defenses that would otherwise reduce those claims. But a significant portion of group health coverage in the United States is not self-funded: it is fully insured through a commercial health insurer, and a fully insured plan is regulated by state insurance law, not ERISA, for purposes of its subrogation or reimbursement rights. Understanding that distinction is the first step in identifying which plans are vulnerable to state-law reduction arguments.
The ERISA vs. Fully Insured Plan Distinction
The key question in any group health subrogation analysis is whether the plan is self-funded or fully insured. A self-funded plan is one in which the employer bears the financial risk of claims payments itself, often using a third-party administrator (TPA) to process claims. Self-funded plans are governed by ERISA, and ERISA preempts state insurance law as applied to them. The Supreme Court in FMC Corp. v. Holliday (1990) held that ERISA preempts state anti-subrogation laws as applied to self-funded plans, which is why fully funded self-insured plans get to enforce contractual reimbursement rights even in states with anti-subrogation statutes.
A fully insured plan is one in which the employer purchases an insurance policy from a commercial health insurer and the insurer bears the risk. The employer pays premiums; the insurer pays claims. Fully insured plans are still ERISA plans for some purposes, but under ERISA Section 514(b)(2)(A), the savings clause preserves state laws that regulate insurance as applied to insured plans. That means state insurance laws, including state anti-subrogation statutes and the common-law made-whole doctrine, apply to fully insured group health plans when the plan's insurer seeks subrogation from a PI settlement.
To determine whether a plan is self-funded or fully insured, obtain the plan's Summary Plan Description (SPD) and Form 5500. The SPD should identify whether the plan is self-funded or insured; the Form 5500 Schedule A will show premium payments if the plan is fully insured. If the TPA is the employer's own administrative entity and there are no premium payments to an external insurer, the plan is almost certainly self-funded. If there is a named insurance carrier and premium payments appear on Form 5500, the plan is fully insured and state law applies to its subrogation claim.
State Anti-Subrogation Statutes
Approximately a dozen states have enacted anti-subrogation statutes that prohibit health insurers from asserting subrogation rights against personal injury recoveries, or that substantially limit those rights. California, New York, and several other large states have variations of these protections. In California, Insurance Code Section 10112.8 requires health insurers to reduce their subrogation or reimbursement demands by the same proportion of attorney's fees and costs that the plaintiff incurred in obtaining the recovery, a provision that mirrors the ERISA plan attorney fee allocation fight but applies here as a mandatory statutory reduction rather than a negotiated concession.
In states with anti-subrogation statutes applicable to insured health plans, the plan's claim may be limited to a specific formula or may be prohibited entirely. Before responding to any group health plan reimbursement demand, verify whether the plan is fully insured and, if so, whether the state's insurance law limits or prohibits the claim. A demand from a Blue Cross or Cigna plan on behalf of a group health policy is potentially subject to state law limitations that simply do not apply to a demand from a self-funded plan administered by the same carrier as TPA.
The Made-Whole Doctrine in State-Regulated Plans
The common-law made-whole doctrine provides that an insurer may not assert subrogation rights against a policyholder's recovery until the policyholder has been fully compensated for all damages. Because ERISA preempts state law for self-funded plans, the made-whole doctrine does not apply to self-funded plan reimbursement demands in most circuits after Montanile v. Board of Trustees. But for fully insured plans governed by state insurance law, the made-whole doctrine is available as a common-law defense in most states that have not abolished it by statute.
The practical application: when a fully insured group health plan asserts a reimbursement demand and the PI settlement does not fully compensate the plaintiff for all damages (a common situation where the defendant's insurance limits are below the full value of the case), the plaintiff can assert the made-whole defense to reduce or eliminate the plan's claim. The plaintiff needs to document the full value of the case: expert life care plans, forensic economic damages analysis, and a demand-value memo that establishes the gap between the settlement and the full value. That documentation supports both the made-whole argument and any negotiated reduction.
Practical Steps in the Lien Resolution Workflow
When you receive a group health plan reimbursement demand, work through these steps before responding or paying:
- Pull the SPD and Form 5500 to confirm whether the plan is self-funded or fully insured. The distinction determines which legal framework applies.
- If fully insured, identify the applicable state insurance law, including anti-subrogation statutes and the status of the made-whole doctrine in the jurisdiction.
- Calculate the attorney fee proportional reduction required by state law, if applicable, and apply it to the gross demand before any further negotiation.
- If the settlement is below the full case value, prepare a made-whole analysis with supporting documentation and present it to the plan before responding to the demand.
- Document all communications with the plan in writing and confirm any agreed reduction in writing before disbursing proceeds.
