Medical Liens in California Personal Injury Cases

By Aryan Amid

Short answer: A medical lien is a claim to be repaid from an injury recovery for care tied to the injury. In California, some types of liens come from state statutes (hospitals, counties, Medi-Cal), some from federal law (Medicare, ERISA plans), and some only from contracts. Each source has its own rules, verified here as of October 28, 2026.

What is a medical lien in a California injury case?

When another party may be liable for an injury, the medical bills are often paid, or held open, by someone else. That payer may claim repayment out of the settlement, judgment, or award.

Some types of liens and reimbursement claims that can attach to a California injury recovery are mapped in the table below. The table is not a frequency ranking. Which claims apply depends on who paid for care and the documents involved. Related background: what a subrogation claim is and what a letter of subrogation is.

Lien or claim typeSourceLimit or measure stated in the source
Hospital lienCiv. Code §§3045.1 to 3045.6Reasonable and necessary charges (§3045.1); a notified payer who pays the injured person without paying the hospital the lien amount, or so much as can be satisfied out of 50 percent of the moneys due after prior liens, is liable to the hospital (§3045.4)

How do California hospital liens work?

Civil Code section 3045.1, verified on October 28, 2026 (America/Los_Angeles) on California Legislative Information, gives a licensed hospital that provides emergency and ongoing services a lien on damages recovered by the injured person, “to the extent of the amount of the reasonable and necessary charges” for those services. It does not apply to injuries covered by workers’ compensation (Labor Code Divisions 4 and 4.5).

Section 3045.3 says the lien is not effective unless written notice is delivered or sent by registered mail to the persons alleged to be liable before they pay, with a copy to any known insurer.

The 50 percent language sits in section 3045.4. It applies to a person or insurer who receives that notice and then pays the injured person “without paying to the association, corporation, public entity, or other institution or body maintaining the hospital the amount of its lien claimed in the notice, or so much thereof as can be satisfied out of 50 percent of the moneys due under any final judgment, compromise, or settlement agreement after paying any prior liens.” That payer “shall be liable” to the hospital “for the amount of its lien claimed in the notice which the hospital was entitled to receive as payment for the medical care and services rendered to the injured person.” Section 3045.5 lets the hospital enforce its lien by an action against the notified payer within one year after the payment.

A separate county care lien can arise under Government Code section 23004.1 when a county furnishes care. If the injured person sues, the county’s right continues as a first lien against the judgment, to the extent of the reasonable value of the care.

How does a Medi-Cal lien work?

Under Welfare and Institutions Code section 14124.71, verified October 28, 2026, the director of the Department of Health Care Services has a right to recover the reasonable value of Medi-Cal benefits provided because of an injury for which another party is liable.

Key steps in the statute:

  • Notice. Section 14124.73(a) calls for written notice within 30 calendar days of filing the action. The DHCS personal injury lien process page, opened October 28, 2026, says to provide notification within 30 days of filing an action or claim and lists the section 14124.73(c) contents.
  • Finality. Section 14124.76(a) states that no settlement, judgment, or award is final or satisfied without first giving the director notice and a reasonable opportunity to perfect and satisfy the lien.
  • Medical portion only. Section 14124.76 limits recovery to the portion representing medical expenses or medical care. Absent the director’s advance agreement, a court decides that portion, guided by Arkansas Department of Health and Human Services v. Ahlborn (2006) 547 U.S. 268.
  • Order of payment. When the beneficiary prosecutes the claim alone, section 14124.74(a) directs that reasonable litigation expenses and attorney’s fees be paid first, and then the director’s lien as a first lien.
  • Lesser method. Sections 14124.72, 14124.76, and 14124.78 each describe a way of figuring the director’s recovery, and section 14124.785 limits recovery to whichever is less.

DHCS says it sends a “lien” or “no lien” letter. Exceptions and tolling rules can move these dates, and waiting for a report generally does not pause them.

How is Medicare repaid after an injury settlement?

42 U.S.C. section 1395y(b)(2), read October 28, 2026 on govinfo (2023 edition), makes Medicare a secondary payer when payment has been or can reasonably be expected to be made under an automobile or liability policy, no-fault insurance, or workers’ compensation. Medicare may make a conditional payment when that primary plan has not paid, or cannot reasonably be expected to pay, promptly. A primary plan, and an entity that receives payment from a primary plan, is required to reimburse Medicare for a payment for an item or service “if it is demonstrated that such primary plan has or had a responsibility to make payment with respect to such item or service,” which a judgment or settlement can show with or without a determination or admission of liability. Under section 1395y(b)(2)(B)(v), the Secretary may waive these provisions, in whole or in part, for an individual claim when the Secretary determines the waiver is in the best interests of the Medicare program.

The statute also lets the United States bring an action against entities that are or were required or responsible to pay under a primary plan, and collect double damages against such an entity in accordance with paragraph (3)(A); it may also recover from an entity that received payment from a primary plan. If reimbursement is not made within the 60-day period after notice of the primary plan’s responsibility is received, the Secretary may charge interest. The CMS recovery process page, opened October 28, 2026, describes reporting the case to the Benefits Coordination and Recovery Center, a Conditional Payment Letter listing related claims, a dispute step for unrelated claims, settlement reporting, and a final demand.

Exceptions and tolling rules can move these dates, and waiting for a report generally does not pause them.

What about employer health plans and ERISA?

The U.S. Department of Labor, page opened October 28, 2026, describes ERISA as a federal law that sets minimum standards for most voluntarily established retirement and health plans in private industry, and notes that ERISA generally does not cover governmental or church plans.

Two U.S. Supreme Court decisions, read on govinfo the same day, shape reimbursement claims by ERISA plans:

  • US Airways, Inc. v. McCutchen (2013) 569 U.S. 88. The case involved a self-funded plan. The Court held that in a section 502(a)(3) action based on an equitable lien by agreement, the plan’s terms govern, and general unjust-enrichment rules cannot override them. Where the plan was silent on how the costs of recovery are paid, the Court used the common-fund doctrine as the default rule.
  • Montanile v. Board of Trustees (2016) 577 U.S. 136. When a participant wholly dissipates a third-party settlement on nontraceable items, the plan may not sue under section 502(a)(3) to attach the participant’s separate assets.

These cases make the specific plan documents central.

How do workers’ compensation and letters of protection fit in?

If a work injury also involves an outside party, Labor Code section 3856(b), verified October 28, 2026, says that when the employee sues alone, the court first orders paid, from any judgment for damages recovered, reasonable litigation expenses and a reasonable attorney’s fee, then allows the employer, on application, a first lien for its compensation expenditure plus amounts under section 3852.

A letter of protection is different. It is an agreement in which a provider treats now and looks to a future recovery for payment. We found no California statute that governs letters of protection, so the contract terms control.

Who asserts a lien, and who gets paid first?

ClaimWho asserts itWho is paid first, per the source
Hospital lienThe hospital, by written notice to the liable party and known insurerA notified payer who pays the injured person without paying the hospital as §3045.4 describes is liable to the hospital for the lien amount it was entitled to receive (§3045.4)
County care lienThe countyFirst lien against the judgment (Gov. Code §23004.1(b))
Medi-Cal lienDHCS directorWhen the beneficiary sues alone: litigation expenses and attorney’s fees first, then the director’s first lien (W&I §14124.74(a))
MedicareCMS through its recovery contractorPrimary plan and recipients of its payment reimburse Medicare for items or services the primary plan was responsible for, subject to waiver (42 U.S.C. §1395y(b)(2)(B)(ii), (v))
ERISA planPlan fiduciary or administratorPlan terms govern (McCutchen)
Workers’ compensation employerThe employerWhen the employee sues alone: litigation expenses and attorney’s fee first from the judgment, then the employer’s first lien (Lab. Code §3856(b))

How do billed charges, paid amounts, and liens interact?

In Howell v. Hamilton Meats & Provisions, Inc. (Cal. Supreme Ct., No. S179115, filed Aug. 18, 2011), the California Supreme Court held that “an injured plaintiff whose medical expenses are paid through private insurance may recover as economic damages no more than the amounts paid by the plaintiff or his or her insurer for the medical services received or still owing at the time of trial.” The Court said it did not modify the collateral source rule. Howell addresses the damages figure for past medical expenses; it is not a rule about how much any lien holder accepts.

Does a California hospital lien take 50 percent of my settlement? Civil Code section 3045.4 does not say that. Its 50 percent language describes the payment to the hospital that the statute looks for from a payer who received the lien notice, after prior liens; a payer who pays the injured person without it is liable to the hospital.

Do I have to tell Medi-Cal about my injury claim? Section 14124.73 calls for written notice within 30 calendar days of filing the action, and DHCS also states 30 days.

Can Medi-Cal take money for pain and suffering? Section 14124.76 limits recovery to the portion representing medical expenses or medical care.

How does Medicare get repaid after an injury settlement? A primary plan and an entity that receives its payment are required to reimburse conditional payments for items or services the primary plan has or had a responsibility to pay for, under 42 U.S.C. section 1395y(b)(2); the Secretary may waive this in whole or in part for an individual claim.

Does my employer health plan have to be repaid from my settlement? For ERISA plans, plan terms govern (McCutchen), with limits on reaching separate assets (Montanile).

What is a letter of protection, and is it the same as a lien? It is a contract with a provider. We found no California statute that governs it.

Key takeaways

  • Some types of liens come from California statutes, some from federal law, and some only from contracts.
  • The 50 percent language in Civil Code section 3045.4 describes the payment to the hospital that the statute looks for from a notified payer, after prior liens; it does not say a hospital takes half of a settlement.
  • Medi-Cal recovery is limited to the medical-expense portion, and a settlement is not final without notice to DHCS (W&I §14124.76).
  • Medicare and ERISA plan claims follow federal law and, for ERISA, the plan’s terms.
  • Letters of protection are contracts; we found no California statute that governs them.

Frequently asked

What is a medical lien in a California personal injury case?

A medical lien is a claim by a provider, a government program, or a health plan to be repaid from an injury recovery for care related to the injury. In California, some types of liens come from statutes, such as the hospital lien law in Civil Code sections 3045.1 to 3045.6, while others come from federal law or a plan or provider contract.

Does a California hospital lien take 50 percent of my settlement?

Civil Code section 3045.4 does not say that. It applies to a person or insurer that receives the hospital's lien notice and then pays the injured person without paying the hospital the amount of the lien claimed in the notice, or so much of it as can be satisfied out of 50 percent of the moneys due after paying any prior liens. That payer is liable to the hospital for the amount of the lien claimed in the notice that the hospital was entitled to receive as payment for the care. The 50 percent text describes the payment to the hospital that the statute looks for from a notified payer; it does not say a hospital takes half of a settlement.

Do I have to tell Medi-Cal about my injury claim?

Welfare and Institutions Code section 14124.73 calls for written notice to the director within 30 calendar days of filing the action, and the DHCS personal injury lien page says notice is due within 30 days of filing. Section 14124.76 says no settlement, judgment, or award is final without notice to the director and a reasonable opportunity to perfect and satisfy the lien.

Can Medi-Cal take money for pain and suffering?

Section 14124.76 limits recovery of the director's lien to the portion of a settlement, judgment, or award that represents payment for medical expenses or medical care. Without the director's advance agreement on that portion, the statute sends the question to a court, guided by Arkansas Department of Health and Human Services v. Ahlborn (2006) 547 U.S. 268.

How does Medicare get repaid after an injury settlement?

Under 42 U.S.C. section 1395y(b)(2), Medicare can make conditional payments when a liability or no-fault insurer has not paid, or cannot reasonably be expected to pay, promptly. A primary plan, and an entity that receives payment from a primary plan, is required to reimburse Medicare for a payment for an item or service if it is demonstrated that the primary plan has or had a responsibility to pay for that item or service, and the statute lets the Secretary waive these provisions in whole or in part for an individual claim. CMS describes a process that starts with reporting the case to the Benefits Coordination and Recovery Center and ends with a demand letter.

Does my employer health plan have to be repaid from my settlement?

It depends on the plan documents and the law that governs the plan. For ERISA plans, the U.S. Supreme Court held in US Airways v. McCutchen that the plan's terms govern a reimbursement claim based on an equitable lien by agreement. In Montanile, it held a plan could not use that remedy to reach a participant's separate assets once the settlement was wholly spent on nontraceable items.

What is a letter of protection, and is it the same as a lien?

A letter of protection is an agreement under which a provider treats now and looks to a future injury recovery for payment. We found no California statute that governs letters of protection; their terms come from the contract itself. That makes them different from statutory liens such as the hospital lien or the Medi-Cal lien.

Do I need to pay for an initial consultation with LA Law Group?
