Your health plan paid for the ambulance and the surgery, and now a letter says it wants that money back from your injury settlement. Can it do that?
Often it can, though not always in full. California subrogation law and a handful of related statutes decide who may seek repayment, how much they can take and what reductions apply. The answer depends on who paid your bills, what your plan or policy says and whether federal law controls the plan.
What Subrogation Means Under California Law
Subrogation lets a payer step into your shoes and pursue the person who caused the harm. For example, your auto insurer pays to fix your car and then seeks that money from the other driver’s insurer.
Reimbursement works a little differently. A health plan that covered your treatment asks you to repay it out of your own recovery. Payers who hold a lien have a legal claim attached to the settlement money itself.
Who Might Ask for Money Back
Several kinds of payers can show up near the end of a claim, and each one follows its own rules:
- Private health plans and health insurers
- Employer health plans governed by federal ERISA law
- Medicare and Medi-Cal
- Hospitals that file a lien
- Your own auto insurer, for repairs or medical payments coverage
- A workers’ compensation carrier on a work injury caused by an outsider
How California Law Caps Subrogation by Health Plans
Civil Code section 3040 limits liens that California-regulated health plans and insurers can assert against a recovery. A plan can claim only what it actually paid to providers, plus its reasonable costs to perfect the lien. For capitated care, the cap is 80 percent of the usual and customary charge.
Firm ceilings come next. With an attorney, the lien is capped at one third of the money due to you under the settlement or judgment. Without an attorney, the ceiling is one half.
A plan’s lien also shrinks in proportion to your attorney fees and costs, and a judgment that finds you partly at fault cuts it by that same percentage. You can read the full text of Civil Code section 3040.
Hospital Liens Under the Hospital Lien Act
Hospitals that treat emergency and ongoing injuries can claim a lien under Civil Code sections 3045.1 through 3045.6. First, the hospital must send written notice to the person or insurer that may owe you money.
Under section 3045.4, a hospital lien can generally be paid from no more than 50 percent of the settlement or judgment after any earlier liens. If an insurer ignores a proper notice and pays you directly, it can end up owing the hospital itself.
Where Federal Law Overrides California Subrogation Rules
Many large employers fund their own health plans. Those self-funded plans fall under ERISA, a federal law, and state caps like section 3040 usually do not bind them. Its plan document may claim full repayment, and the exact wording matters a great deal.
Ask the plan administrator for the summary plan description and the full plan document early. You can also see who pays medical bills while a claim is pending and how these plans fit alongside other coverage.
Repayment to Medicare and the State Medicaid Program
Medicare’s repayment right comes from the federal Medicare Secondary Payer rules. You or your representative report the claim to Medicare’s recovery contractor. Medicare responds with a conditional payment notice listing what it paid. A CMS coordination of benefits and recovery page walks through that process.
Medi-Cal’s rights come from Welfare and Institutions Code section 14124.70 and the sections after it. When you bring the claim and pay your own attorney, section 14124.72 reduces the Medi-Cal lien by 25 percent for its share of fees, plus a share of costs. Section 14124.78 adds that the state cannot recover more than you keep after attorney fees and litigation costs.
Your Own Auto Insurer and Medical Payments Coverage
If your insurer paid for repairs, it usually chases the other driver’s carrier on its own. A successful recovery may return your collision deductible to you.
Medical payments coverage varies by policy. Some policies include a reimbursement clause that lets the insurer recover from your injury settlement, and others do not. Under California subrogation law the policy wording usually controls here, so read that section before you sign anything.
Work Injuries and Subrogation Under California Law
Say a delivery driver is rear-ended on Florin Road while on the job. Workers’ compensation pays medical bills and wage benefits, and the driver has a claim against the other motorist.
Under Labor Code section 3856, the court pays litigation costs and attorney fees first, then allows the employer a lien for what it paid. Section 3858 has long let the employer take a credit against future benefits. But a 2025 amendment that took effect January 1, 2026, removes that credit in cases covered by section 3852(b). California subrogation law in this area just changed, so check the current text.
The Made Whole Idea
Courts sometimes apply a made whole rule. It asks whether the injured person was fully paid for every loss ahead of any insurer. With a small settlement and serious harm, this rule can matter.
Contracts and federal law can limit or override it, though. Whether it helps you depends on the payer and the exact plan language.
A Sacramento Example
Imagine a Rancho Cordova nurse hurt in a T-bone crash on Sunrise Boulevard. Her Kaiser plan paid $30,000, a hospital lien claims $12,000 and her case settles for $90,000 with an attorney.
In this hypothetical, the Kaiser lien starts at $30,000 and drops by her share of fees and costs, and it can take no more than a third of her recovery. Separately, the hospital lien is limited to half of the recovery after prior liens. Small differences in the math can change her net amount by thousands of dollars.
Common Mistakes With Liens
- Settling with some payers still unknown
- Paying a lien without an itemized statement
- Assuming every plan must follow section 3040
- Ignoring a Medicare conditional payment letter
- Missing unrelated charges buried in the lien total
Steps When a Payer Wants Repayment
- Ask each payer for a written, itemized statement.
- Match every charge to treatment for this injury.
- Request the plan or policy language the payer relies on.
- Keep every lien letter in one folder with dates.
Pay stubs and benefit records often sit next to lien papers, and the post on documenting lost income after an injury covers those.
Questions About Repayment Claims
Does every health plan have to reduce its lien?
No. Section 3040 covers plans and insurers regulated by California, such as Knox-Keene plans and state-licensed disability insurers. Self-funded employer plans under ERISA usually follow their own plan terms, and Medicare and Medi-Cal follow separate rules. So the first question is always who paid and under what kind of plan.
Can I negotiate a lien?
Often you can. Payers sometimes agree to reductions for hardship, limited insurance or disputed charges, and the statutes above set floors on certain reductions. Ask in writing, explain the reason and keep a copy of every reply you receive from the payer.
What happens if a lien is ignored?
Ignoring a valid lien can cause trouble later. A hospital or plan may pursue you or the insurer that paid, and Medicare can charge interest on unpaid amounts it is owed. Resolving liens ahead of the payout protects both you and the settlement.
Repayment claims can quietly shrink a settlement, so identify every payer early and get an itemized statement from each one. Then check which rule applies, because a state plan, a federal plan and Medi-Cal each follow different limits. More posts on bills and liens are in the compensation hub.
