Overview

Subrogation and lien resolution is one of the most complex and consequential aspects of California personal injury practice. When a plaintiff recovers damages, various entities that paid for the plaintiff's care -- health insurers, government programs, employers through workers' compensation -- assert rights to reimbursement. Failure to properly identify, negotiate, and resolve these liens can result in malpractice liability, delayed resolution, and drastically reduced net recovery.

Key takeaway
Subrogation and lien resolution is not an afterthought -- it is an integral part of case management that begins at intake and directly affects the client's net recovery. A $500,000 settlement can yield very different net results depending on how liens are identified, negotiated, and resolved.

Health Insurance Subrogation

When a health insurer pays for treatment related to a third-party injury, it may have a right of subrogation. The scope depends on the plan type. For plans governed by California law, the made-whole doctrine prevents recovery until the insured is fully compensated, and Civil Code 3040 limits recovery to amounts paid and requires pro rata attorney fee sharing. Self-funded ERISA plans preempt state protections but must still share fees under the common fund doctrine.

ERISA Preemption and Self-Funded Plans

ERISA preempts state-law protections for self-funded employer health plans. However, under US Airways v. McCutchen (2013), the common fund doctrine requires fee-sharing even for ERISA plans. Challenge ambiguous plan language, scrutinize equitable limitations, and negotiate aggressively -- even self-funded plans will often accept reductions to avoid litigation costs.

Medicare Conditional Payments

Medicare's reimbursement right under the Medicare Secondary Payer Act is a federal super-lien that cannot be waived, is not subject to state-law limits, and creates double-damages liability for failure to reimburse. Start the MSPRP process early -- resolution is notoriously slow. Request conditional payment letters months before anticipated settlement. Medicare must reduce its demand by a proportionate share of attorney fees.

Never settle without addressing Medicare
Settling without resolving Medicare's conditional payment lien can result in personal liability for the attorney, double damages under the MSP Act, and loss of the client's Medicare benefits. Always identify Medicare involvement at intake.

MediCal Recovery

Welfare and Institutions Code 14124.70 creates an automatic statutory lien for DHCS. MediCal rates are significantly below market, so lien amounts are typically lower. DHCS will reduce the lien by 25% for attorney fees and may further compromise based on recovery amount and client hardship.

Workers' Compensation Liens

When an employee is injured by a third party and receives workers' comp benefits, the insurer has a lien on the third-party recovery under Labor Code 3852. The lien covers medical expenses, temporary and permanent disability, and vocational rehabilitation. The lien is reduced by a proportionate share of attorney fees (typically 25% under Labor Code 3856).

Lien Negotiation Best Practices

Identify all liens at intake. Notify lienholders promptly. Track liens throughout the case. Begin negotiation before settlement closes. Allocate settlement proceeds strategically -- higher allocation to non-economic damages reduces medical liens. Never disburse without resolving liens.

Common Questions

What is subrogation in a personal injury case?
Subrogation is the right of an entity that paid for your medical care -- such as your health insurer, Medicare, or MediCal -- to be reimbursed from your personal injury settlement or judgment. The entity essentially steps into your shoes to recover what it paid. Not all subrogation rights are equal: some can be significantly reduced through negotiation.
Can my health insurance company take part of my settlement?
It depends on your plan type. For plans governed by California law, the made-whole doctrine and Civil Code 3040 limit what the insurer can recover, and the insurer must share in attorney fees. For self-funded ERISA plans, federal law preempts state protections, though the common fund doctrine still requires fee-sharing. Either way, aggressive lien negotiation can significantly reduce the amount.
What happens if I don't pay back Medicare from my settlement?
Failure to reimburse Medicare can result in double damages under the Medicare Secondary Payer Act, personal liability for your attorney, potential loss of Medicare benefits, and malpractice exposure. Medicare's reimbursement right is created by federal statute and cannot be waived. Always address Medicare conditional payments before disbursing settlement funds.
How much can I reduce my medical liens?
Reductions vary by lien type. Health insurance liens governed by California law must be reduced by a pro rata share of attorney fees (typically one-third). Medicare must reduce for procurement costs. MediCal reduces by 25% for fees. Beyond mandatory reductions, most lienholders will negotiate additional reductions of 30-50% or more, particularly when the settlement is modest relative to total damages.
