What Is ERISA Preemption in Personal Injury?

ERISA preemption allows employer-sponsored health plans to override state anti-subrogation laws, forcing PI attorneys to reimburse those plans even in states that would otherwise protect the client. Here's what every PI attorney needs to know.

The Federal Law That Overrides California

California has relatively favorable laws for personal injury plaintiffs when it comes to health plan subrogation. The made-whole doctrine, codified in California's statutory scheme, often limits health insurers' ability to recover from a settlement if the plaintiff was not fully compensated.

But there is an important exception that catches many attorneys off guard: ERISA preemption.

The Employee Retirement Income Security Act of 1974 (ERISA) governs employer-sponsored benefit plans, including health plans offered through private employers. ERISA contains a broad preemption clause that displaces state laws "related to" employee benefit plans. This means California's made-whole doctrine, anti-subrogation laws, and other protective state statutes may not apply to health plans governed by ERISA.

The result: an employer-sponsored health plan can demand full reimbursement of its subrogation interest from a personal injury settlement, even if your client was not made whole.

[!KEY] ERISA preemption eliminates California's made-whole doctrine for employer-sponsored health plans — a self-funded ERISA plan can demand full subrogation reimbursement from a PI settlement even when the plaintiff received far less than their total damages.

What ERISA Preemption Does to Subrogation Rights

In an ERISA-governed plan, the health plan's subrogation and reimbursement rights are typically defined in the Summary Plan Description (SPD). When a plan member (your client) recovers money from a third party that caused injuries the plan paid to treat, the plan can seek reimbursement directly from those settlement proceeds.

Under US Airways v. McCutchen (2013), the U.S. Supreme Court confirmed that ERISA plan terms generally control the recovery amount — subject only to federal equitable principles, not state law defenses. This means that even if California would protect your client under state law, an ERISA plan can sue in federal court to enforce its full contractual subrogation interest.

Common ERISA plan provisions attorneys encounter:

• Full reimbursement clauses — the plan gets back 100% of what it paid, regardless of how small the settlement was.
• First-dollar recovery clauses — the plan takes its amount from the first dollars received, before the plaintiff receives anything.
• Anti-reduction clauses — the plan expressly refuses to apply the made-whole doctrine.

ERISA vs. State Anti-Subrogation Laws

To understand why this matters, consider the two tracks:

State-law plans (individual insurance, small employer fully-insured plans, Medi-Cal) are subject to California's Insurance Code, the made-whole doctrine, and judicial interpretation of subrogation in equity. These plans often negotiate significant reductions.

ERISA plans (most large-employer self-funded health benefits) are governed by federal law. State statutes and equitable doctrines that would limit subrogation recovery either do not apply or apply only to the extent the ERISA plan's terms allow.

The practical consequence: the same injury, the same settlement, and the same client can face very different outcomes depending on whether their health plan is state-governed or ERISA-governed.

How to Identify an ERISA Plan

This is the first question you should ask at intake: Is your health plan through your employer?

If yes, the next question is whether it is a self-funded plan. Self-funded employer plans (where the employer bears the risk and insurance just administers claims) are virtually always ERISA-governed and receive the strongest preemption protection.

Fully-insured employer plans (where the employer pays premiums to an insurer who bears the risk) may receive less ERISA protection in some states, though California courts have generally extended preemption to these plans as well.

To confirm, request a copy of the Summary Plan Description. ERISA-governed plans are required to provide the SPD on request. If the SPD references ERISA and contains subrogation provisions, treat the plan's recovery right as a federal claim not subject to California's protective doctrines.

ERISA and Pharmacy Liens: Key Distinctions

ERISA subrogation is a completely separate issue from a pharmacy lien. A pharmacy lien — like those from LienScripts — exists because the pharmacy extended medication credit to the patient directly. The pharmacy is not seeking to recover what it paid through your client's health plan. It provided a service on credit and holds a contractual lien.

ERISA has no bearing on pharmacy liens because the pharmacy is not an "employee benefit plan" and the lien does not arise from plan benefits. The two claims exist in parallel and are resolved independently.

[!KEY] The independence of pharmacy liens from ERISA is a critical distinction at settlement — when an attorney is negotiating a large ERISA subrogation demand, the pharmacy lien balance is a separate line item paid from the plaintiff's net share, not from the ERISA plan's recovery, and conflating the two leads to either overpaying the plan or underpaying the pharmacy.

For more on how subrogation and pharmacy liens interact at settlement, see our post on what subrogation means in personal injury and the pharmacy lien settlement waterfall.

[!TIP] For Attorneys: At intake, ask whether the client's health plan is employer-sponsored and self-funded — if so, request the Summary Plan Description immediately and treat any subrogation provision as a federal claim not subject to California's protective state statutes.

Common Strategies for Attorneys

Even under ERISA, attorneys have tools to minimize the plan's recovery and protect their client's net proceeds:

1. Negotiate on equity grounds. Federal courts have found that ERISA plans must act in good faith and cannot unjustly enrich themselves at the plaintiff's expense. Equitable arguments under McCutchen and subsequent cases can reduce the plan's recovery even without California law.

2. Challenge which charges are injury-related. Request an itemized accounting of what the plan paid. Not every charge in the plan's subrogation demand relates to the injury. Challenging unrelated medical expenses can reduce the claim significantly.

3. Proportionality arguments. When the settlement amount is a fraction of total damages, some courts recognize that proportionate allocation limits the plan's recovery to its share of the total damages, not the total settlement.

4. Attorney fee deduction. Most ERISA plans are subject to a common fund doctrine that requires them to contribute to the attorney's fee for obtaining the recovery from which they benefit. Negotiate a reduction to account for your contingency fee.

5. Early negotiation. ERISA plans are often administered by third-party administrators (TPAs) who have authority to negotiate. Engage them early — before the settlement is finalized — to lock in a reduced figure.

[!KEY] The attorney fee deduction argument — requiring the ERISA plan to contribute a proportionate share of the contingency fee because the attorney's work produced the fund from which the plan recovers — is available in virtually every ERISA case and should be raised in the first negotiation contact, not as an afterthought.

Key Takeaway

ERISA preemption is one of the most significant variables in any PI settlement involving employer-sponsored health coverage. It eliminates California's made-whole protection and forces full reimbursement of the plan's subrogation interest under federal terms. Identifying ERISA plans at intake, obtaining the SPD early, and engaging in timely negotiation are the most effective ways to protect your client's net recovery.
