California Limits What a Hospital Lien Can Take From Your Injury Settlement
If a hospital treated you after a crash, a fall, or an assault, it may send a lien letter claiming part of your settlement.
California's Hospital Lien Act limits that lien to reasonable and necessary charges, and caps what a paying party owes the hospital at half of the recovery left after prior liens.
A hospital that already accepted your health plan's payment as payment in full has no lien at all.
Medi-Cal can recover only from the part of a settlement that pays for medical care, and its claim is generally reduced to account for your attorney's fees.
Each of those rules can change what reaches your pocket.

At a Glance: California Medical Liens
- A hospital lien is limited to reasonable and necessary charges under Civil Code § 3045.1 and needs registered-mail notice before payment under § 3045.3
- A party who pays after notice owes the hospital no more than 50 percent of the recovery left after prior liens, under § 3045.4
- No hospital lien exists when the hospital accepted a health plan's payment as payment in full (Parnell, 2005)
- Medi-Cal recovers only from the medical-expense share of a settlement, reduced for fees and costs, under Welfare and Institutions Code §§ 14124.72-14124.785
- A health plan's lien is capped at one-third of the recovery when you have a lawyer, under Civil Code § 3040
When a Hospital Can Put a Lien on Your California Injury Settlement
Civil Code § 3045.1 gives a licensed hospital that provides emergency and ongoing care to someone hurt by an accident or a wrongful act a lien on the damages that person, or their heirs, recover from the party responsible. The lien is limited to the hospital's "reasonable and necessary charges," and it does not apply to workers' compensation.[1]
The lien works through notice. Under § 3045.3, it binds the responsible party only if the hospital delivers written notice, or mails it by registered mail with return receipt, to each party alleged to be liable and to its known insurer before the settlement is paid. A party that pays after receiving notice without honoring the lien can be sued by the hospital, within one year of the payment.
The Act does not reach every claim. It does not apply to claims against common carriers regulated by the Public Utilities Commission, and it does not create a lien where the patient owes the hospital nothing.
A hospital that sends notice late, to the wrong party, or by the wrong method may have no enforceable lien against the settlement, which makes the notice itself the first document to check.
The 50 Percent Ceiling in Civil Code § 3045.4
The Act caps what the hospital can collect from a paying party at "50 percent of the moneys due under any final judgment, compromise, or settlement agreement after paying any prior liens."[2]
On a $100,000 settlement with no prior liens, the hospital's share cannot exceed $50,000, however large its bill. If a $20,000 lien comes first, the ceiling is half of the remaining $80,000, or $40,000. The hospital's charges also have to be reasonable, so the ceiling is a maximum rather than a number the hospital automatically receives.
The statute does not mention attorney's fees. Injury lawyers commonly treat the fee as a prior lien that comes off before the 50 percent is calculated, relying on the priority the California Supreme Court gave attorneys' liens in Cetenko v. United California Bank, but no appellate decision has settled how § 3045.4 treats it.
The arithmetic matters most in a serious injury with modest insurance, where an uncapped hospital bill could otherwise take most of the recovery.
Why Payment in Full From Your Health Plan Ends the Hospital's Lien
In Parnell v. Adventist Health System/West, the California Supreme Court held that a hospital that accepted a health plan's payment as payment in full cannot assert a Hospital Lien Act lien for the rest of its bill, because the lien "requires the existence of an underlying debt owed by the patient to the hospital."[3] In a 2014 case involving Dameron Hospital and Kaiser, the Court of Appeal applied the same rule to a hospital whose contract with Kaiser treated Kaiser's payment as payment in full.
Give the hospital your health insurance information and ask that the bill go to your plan. A hospital that bills your health plan is generally limited to what the plan's contract allows, and your plan's own reimbursement claim is capped by state law.
Paperwork signed at admission can matter too. In 2022, the Court of Appeal held in a case against AAA that a hospital's admission form could not assign an insured patient's auto benefits to the hospital, and could not reach an uninsured patient's uninsured motorist benefits.
Whether you had health insurance at the time of treatment, and whether the hospital used it, is one of the first questions in sorting out a California lien.
Medi-Cal's Lien Reaches Only the Medical Share Under § 14124.76
When Medi-Cal paid for your treatment, the state has a right to be repaid from your recovery, with limits written into the Welfare and Institutions Code.
- Notice. Whoever files the claim must notify the other side within 30 days, and no settlement is final until the Department of Health Care Services has had notice and a chance to assert its lien.
- The medical share only. Under § 14124.76, Medi-Cal's recovery "is limited to that portion of a settlement, judgment, or award that represents payment for medical expenses."[4] If the parties cannot agree on the allocation, a court decides it, guided by the U.S. Supreme Court's decision in Arkansas Department of Health and Human Services v. Ahlborn.
- A reduction for your lawyer. Under § 14124.72(d), when you hired a lawyer and pay fees, Medi-Cal's claim is reduced by 25 percent, and it pays a share of the litigation costs.
- Never more than your net. Section 14124.78 limits the state to what you net after fees and costs, and § 14124.785 applies whichever formula produces the lowest figure.
A settlement allocated carefully between medical expenses and the other losses it compensates can make a real difference in what Medi-Cal takes.
Medicare, Health Plan, and Workers' Comp Liens on a California Settlement
Hospitals and Medi-Cal are not the only ones with a claim to repayment. The rules for each lienholder differ, and so do the reductions.
| Lienholder | What limits the claim | Law |
|---|---|---|
| Hospital (no health coverage used) | Reasonable charges; 50 percent of the recovery after prior liens; no lien if paid in full by a health plan | Civ. Code §§ 3045.1-3045.6 |
| Health plan or insurer | Amount actually paid; one-third of the recovery with a lawyer, one-half without; reduced pro rata for fees and costs and for any fault finding | Civ. Code § 3040 |
| Medi-Cal | Medical-expense share only; 25 percent fee reduction; never more than your net | Welf. & Inst. Code §§ 14124.72-14124.785 |
| Medicare | Conditional payments must be repaid, reduced by Medicare's share of the cost of obtaining the recovery | 42 U.S.C. § 1395y(b); 42 C.F.R. § 411.37 |
| Workers' comp carrier | Repaid from a third-party recovery after litigation costs and attorney's fees | Labor Code § 3856 |
The § 3040 cap does not apply to Medi-Cal, workers' compensation, or hospital liens, and a self-funded employer plan governed by federal law may claim it is outside state limits altogether. Identifying which kind of plan paid is the first step in knowing which rules apply.
How California Courts Value Medical Bills Owed on a Lien
Liens raise a second question, which is what the medical bills are worth as damages in the first place. In Howell v. Hamilton Meats & Provisions, the California Supreme Court limited an insured plaintiff's past medical damages to "the amounts paid by the plaintiff or his or her insurer for the medical services received or still owing at the time of trial," not the full billed amount.[5]
When a person treats on a lien, the rules shift. Under Pebley v. Santa Clara Organics (2018), an insured plaintiff who chooses to treat outside the plan on a lien basis may be treated as uninsured, so the bills can be used to prove the amount incurred and its reasonable value. Qaadir v. Figueroa (2021) added that unpaid lien bills count only if the plaintiff shows they were actually incurred, and that evidence of an attorney's referral to the treating doctor can be relevant. In Moore v. Mercer (2016), the court held that a plaintiff's damages are not capped at the discounted price a medical finance company paid for the bills.
How your care was billed, through insurance, Medi-Cal, or a lien, therefore shapes both the value of the claim and the size of the liens against it, which is why the two are worked out together.
SB 623 Changes Lien Bills in Rideshare and Delivery-App Cases From 2027
For crashes on or after January 1, 2027, involving an Uber or Lyft driver, a delivery-app courier, or the company itself, a 2026 law adds Civil Code § 3333.9. Past medical expenses from a lien-based provider are capped at the 70th percentile of FAIR Health billed charges for the same service in the same area, and a lien that was sold is capped at the price the buyer paid.
The law also makes referral and financing relationships between lawyers and lien providers discoverable, and it does not affect care paid through health insurance, Medi-Cal, Medicare, or the Hospital Lien Act. The full picture is on our page about rideshare accident law after SB 623.
Outside those cases, nothing in SB 623 changes how liens work in an ordinary California car crash or fall.
Clearing Every Lien Before Your Share of a California Settlement Is Paid
Liens are paid out of the settlement before you receive your share, so the order and the amount of each one decide your net. The work happens in a predictable sequence.
- Identify every lienholder. Hospital, health plan, Medi-Cal, Medicare, workers' comp, and any provider that treated on a lien.
- Get itemized bills. Charges with billing codes, not a single balance, so duplicate and unrelated charges can be found.
- Apply the statutory limits. The 50 percent ceiling, the § 3040 caps, the Medi-Cal formulas, and the Medicare procurement-cost reduction.
- Negotiate the remainder. Most lienholders accept less than their claim, especially when the recovery is limited by insurance.
- Get written final amounts before the settlement funds are distributed.
A settlement that looks fair on paper can leave little for the injured person once the liens are paid, which is why the second opinion our page on reviewing a California settlement offer describes includes the lien stack.
