Legal terms are applied differently depending on the facts of each case and the jurisdiction. Consult a licensed California attorney for guidance specific to your situation.
Subrogation is the substitution of one party (the subrogee, typically an insurer) in place of another (the subrogor, the insured) with respect to a legal claim or right. Upon paying a covered loss, the insurer acquires the insured's right to recover that amount from the tortfeasor responsible for the loss. In California, subrogation rights are governed by common law principles and specific statutory provisions including Insurance Code section 11580.2(d) for uninsured motorist coverage.
An insurer's right to recover — from the at-fault party — what it paid to cover the insured's loss.
Subrogation in Personal Injury Cases
Subrogation is an invisible but financially significant part of nearly every personal injury settlement — insurers who paid the plaintiff's medical bills typically have a right to reimbursement from any recovery against the defendant.
In a typical personal injury case, multiple payors may have covered the plaintiff's losses before a settlement is reached: health insurance, workers' compensation, disability insurance, Medicare, or Medicaid (Medi-Cal in California). Each of these payors may hold a subrogation right against the plaintiff's tort recovery.
Health insurance subrogation. If a private health insurer paid medical bills related to the accident, it typically has a contractual and/or equitable right to reimbursement from any personal injury settlement or judgment. The specific subrogation language in the plan governs. ERISA-governed employer health plans have particularly strong subrogation rights under federal law.
Medicare and Medi-Cal. Medicare and Medi-Cal have statutory liens (not just subrogation rights) that are mandatory — the plaintiff's attorney must account for and resolve these liens before disbursing settlement funds. The Medicare Secondary Payer Act makes the attorney potentially liable if Medicare liens are not satisfied from the settlement.
Workers' compensation. When an injury occurs in the workplace, the employer's workers' compensation carrier has a statutory lien (Labor Code § 3856) against any third-party tort recovery up to the amount of benefits paid. This is technically a lien rather than pure subrogation but operates similarly.
Uninsured motorist. When the plaintiff's own insurer pays an uninsured motorist claim, it acquires subrogation rights against the uninsured at-fault driver under Insurance Code section 11580.2(d).
The "made whole" doctrine. California follows the made-whole doctrine, which generally requires that the insured be fully compensated before the insurer can enforce subrogation rights. If the settlement is inadequate to fully compensate the plaintiff, the plaintiff's recovery takes priority over the insurer's subrogation claim.
No insurer shall be permitted to recover under this subdivision unless the insured has been made whole by all available sources of recovery, including but not limited to, the payment of the policy limits by the uninsured motorist coverage.
How Subrogation Works in Practice
A concrete example: Maria is injured in a car accident. Her health insurer (Blue Shield) pays $40,000 in medical bills. She later settles with the at-fault driver for $80,000. Blue Shield asserts a $40,000 subrogation lien against the settlement.
Before Maria's attorney distributes the settlement funds, they must resolve the Blue Shield lien. If the $80,000 settlement fully compensates Maria for all her losses (medical, wage loss, pain and suffering), Blue Shield receives $40,000 from the settlement. If the $80,000 settlement is insufficient to fully compensate Maria — perhaps her total damages are $150,000 — California's made-whole doctrine may limit or eliminate Blue Shield's right to recover.
Negotiating down subrogation liens is a common and important part of personal injury practice. Insurers sometimes agree to reduce their lien in exchange for prompt payment, particularly when the settlement is limited by the defendant's insurance policy limits. The net recovery to the plaintiff — after attorney fees, costs, and subrogation liens — determines the practical value of a settlement.
ERISA health plans (employer-sponsored plans governed by federal law) present a different and more complicated situation. Federal law may preempt the California made-whole doctrine for ERISA plans, giving those insurers stronger subrogation rights.
State-by-State Variations
Subrogation rights exist in every state, but their scope and limitations vary significantly:
The made-whole doctrine is recognized in most states but with varying strength. Some states have codified it by statute; others apply it as an equitable principle. A minority of states do not recognize the made-whole doctrine for contractual subrogation claims in insurance policies that expressly waive it.
ERISA preemption applies nationwide, meaning employer health plan subrogation is governed by federal law regardless of state limitations. The U.S. Supreme Court has confirmed that ERISA plans can contractually override state anti-subrogation rules.
Some states (like Wisconsin and Minnesota) have anti-subrogation statutes that limit health insurers' ability to recover from personal injury settlements. These laws have been partially preempted by ERISA for employer plans.
Medicaid (Medi-Cal) lien rules vary by state, subject to the minimum requirements of the federal Medicaid statute.
