Health Insurance Subrogation in Personal Injury Claims — What You Must Know

## What Is Subrogation and Why Does Your Health Insurer Want Your Settlement?

Subrogation is the legal principle that allows your health insurer to "step into your shoes" and recover from the party who injured you the medical costs the insurer paid on your behalf. If your health insurance paid $50,000 for treatment of your car accident injuries and you later receive a $150,000 settlement from the at-fault driver, your insurer has a subrogation claim for some or all of that $50,000 — which must be resolved before you receive your net settlement proceeds.

ERISA-governed employer-sponsored health plans have the most powerful subrogation rights of any health insurer — they are governed by federal law, not state law, which means state-level "made whole" protections that would reduce other insurers' subrogation claims do not apply to ERISA plans.

Types of Health Insurance Plans and Their Subrogation Rights

ERISA plans (employer-sponsored self-funded health plans): The most powerful subrogation claimants. Governed by federal ERISA law rather than state law. "Made whole" doctrine (which prevents recovery unless the plaintiff is fully compensated) does not apply in most circuits. Very limited reduction negotiation leverage.

Fully insured employer health plans: Governed by state law. Most states have "made whole" doctrines that prevent insurers from recovering subrogation unless you receive full compensation for all your damages. Stronger negotiation leverage than ERISA plans.

Individual health insurance (marketplace and private plans): Governed by state law and the specific policy terms. May be subject to state "made whole" and "anti-subrogation" protections.

Medicare Advantage plans: Governed by federal law and assert subrogation rights like traditional Medicare. Must coordinate with Medicare's conditional payment system.

Strategies for Reducing Health Insurance Subrogation Liens

**Common fund reduction:** When the plaintiff's attorney generates the recovery that makes subrogation possible, the insurer should contribute proportionally to the attorney fees and costs — typically a 1/3 reduction of the lien
**Made whole doctrine:** In applicable states, argue that your total damages substantially exceeded your settlement, meaning you were not "made whole" and subrogation should be waived or reduced
**Policy language analysis:** Some health insurance contracts have subrogation provisions that do not cover all categories of damages — narrowing the recoverable amount
**Proportionality argument:** When the settlement covers only a fraction of your proven damages (due to policy limits), argue that the subrogation lien should be reduced proportionally
