Medical Liens & Letters of Protection in CA
You were hurt in an accident, you need an MRI or surgery, and you have no idea how you'll pay for it. Meanwhile the at-fault driver's insurance company isn't going to hand you a check today — those payouts come at the end of a case, sometimes a year or more later. So how do injured people get treated in the meantime? In California, there are several ways: your own health insurance, auto medical payments coverage, a medical lien, or a letter of protection. Each lets you get care now and sort out the bill later — but they're not the same, and the choice affects how much money actually lands in your pocket at the end. Hurt Advice is not a law firm and does not provide legal advice. This article is general information about California law, not advice about your situation. Statutes, dollar figures, and case law change, and how they apply depends on the specific facts of your case.

Step-by-step
What to do next
These steps are ordered for usefulness: safety and records first, then insurance, medical, and review decisions.
1
Identify how your care is being paid
Figure out which of the four options applies to you: your own health insurance (private, Medi-Cal, or Medicare), auto MedPay coverage, a medical lien, or a letter of protection. Each affects your final recovery differently.
2
Use health insurance when you can
If you have private insurance, Medi-Cal, or Medicare, it can pay accident-related bills at a negotiated rate usually far below a provider's sticker charges — often the cheapest route for you, though your plan may later assert a reimbursement right against any recovery.
3
Understand the lien payout order
When your case settles, the payout typically flows: gross settlement, minus attorney's fees and case costs, minus medical liens and reimbursement claims, equals your net recovery. The more owed to lienholders, the less is left for you.
4
Track which liens are statutory vs. contractual
Hospital liens may arise under the Hospital Lien Act; liens from surgeons, chiropractors, and imaging centers typically arise from a contract you signed. Government program reimbursements (Medi-Cal, Medicare) have their own rules. Confirm characterizations with an attorney.
5
Negotiate liens down before the case closes
Lien amounts are frequently reduced — because the settlement is too small to pay everyone in full, charges exceed what's reasonable, statutory reductions apply, or the lienholder wants prompt payment. This is detailed, deadline-sensitive work best handled by an experienced attorney.

Your Options
The four common ways to get treated with no money upfront
In California there are four common ways to get medical care now and sort out the bill later. First, your own health insurance — private insurance, Medi-Cal, or Medicare can pay accident-related bills like any other injury, often at a negotiated rate far below the provider's sticker charges. This is often the cheapest route for you, but if you later recover money from the at-fault party, your health plan may have a right of reimbursement on that recovery. Second, auto medical-payments (MedPay) coverage — an optional add-on to a California auto policy that pays medical bills regardless of fault, typically up to a set limit. MedPay is not required in California, so you only have it if you bought it. Third, a medical lien — a provider agrees to treat you now in exchange for a written promise to be paid out of your eventual settlement or judgment. Fourth, a letter of protection (LOP) — usually a letter from your attorney to a provider promising the bill will be paid from any settlement or verdict. An LOP functions much like a lien arrangement and is common when an injured person has no health insurance; it is a contractual promise, not a statutory lien. These characterizations should be confirmed with a licensed California attorney.
- Your own health insurance — private, Medi-Cal, or Medicare; cheapest route but may carry a reimbursement right.
- Auto MedPay coverage — optional in California, pays regardless of fault up to a set limit.
- A medical lien — provider treats you now and collects from your recovery later.
- A letter of protection — a contractual promise, often from your attorney, common when you have no health insurance.
How Liens Work
What a lien actually means for your settlement
A lien is a legal claim against your recovery. When your case settles, the lienholders generally get paid before you do, out of the same pot of money. A simplified payout often looks like this: start with the gross settlement amount, subtract attorney's fees and case costs, then subtract medical liens and reimbursement claims (health plan, hospital, lien-based providers), and what remains is your net recovery. This is why two people with the same one-hundred-thousand-dollar settlement can walk away with very different amounts. The more that's owed to medical lienholders, the less is left for you — which is exactly why negotiating those liens down matters so much. You can model this trade-off with the Settlement Calculator.
- Start with the gross settlement amount.
- Subtract attorney's fees and case costs.
- Subtract medical liens and reimbursement claims from health plans, hospitals, and lien-based providers.
- What remains is your net recovery.
The Statute
California's Hospital Lien Act
California has a specific statute that lets hospitals assert a lien for emergency and ongoing care they provide to someone injured by another's negligence, found at California Civil Code sections 3045.1 through 3045.6 (the Hospital Lien Act). The statute spells out several key points, though each should be verified with an attorney. A licensed hospital has a lien on the injured person's recovery for the reasonable and necessary charges of the care it provided. The lien reaches damages the injured person recovers from the at-fault party by judgment, settlement, or compromise. Before any payment is made to the injured person, the hospital must give written notice to the at-fault party and their insurer; a hospital that doesn't perfect its lien this way may lose the ability to enforce it. Under the 50 percent rule, a party that pays the injured person without satisfying a perfected hospital lien can be liable to the hospital, but the hospital's reach against that payer is limited to what can be satisfied out of 50 percent of the money due, after prior liens. The hospital generally must bring an enforcement action within one year after payment was made. Importantly, the Hospital Lien Act applies to hospitals; liens from other providers such as surgeons, chiropractors, and imaging centers typically arise from a contract you signed, not from this statute.
- Covers a licensed hospital's reasonable and necessary charges (Civ. Code § 3045.1).
- Attaches to recoveries by judgment, settlement, or compromise (Civ. Code § 3045.2).
- Requires written notice to the at-fault party and insurer to perfect the lien (Civ. Code § 3045.3).
- The 50% rule caps the paying party's exposure, not necessarily the patient's underlying debt (Civ. Code § 3045.4).
- The hospital generally has one year to bring an enforcement action (Civ. Code § 3045.5).
Government Programs
Medi-Cal and Medicare reimbursement
If a government program paid for your accident care, it usually has a right to be reimbursed from your recovery. For Medi-Cal, California law lets the state recover what it paid, but with built-in reductions: by statute, Medi-Cal's claim is commonly reduced by 25 percent to account for attorney's fees, plus a share of litigation costs, and overall the state generally cannot recover more than the beneficiary nets after fees and costs (see Welfare & Institutions Code sections 14124.72 and 14124.78). For Medicare, reimbursement rights arise under federal law (the Medicare Secondary Payer rules) and have their own resolution process. These rules are technical and the numbers can move, so confirm the specifics with an attorney. This is one of the strongest reasons to have a lawyer handle lien resolution rather than guessing.
- Medi-Cal can recover what it paid, but with statutory reductions for attorney's fees and costs.
- Medi-Cal generally cannot recover more than the beneficiary nets after fees and costs.
- Medicare reimbursement arises under the federal Medicare Secondary Payer rules.
- These technical rules are a strong reason to have a lawyer handle lien resolution.
Billed vs. Paid
Why billed charges aren't always what you owe: the Howell rule
Medical bills are notoriously inflated compared to what insurers actually pay. California's Supreme Court addressed this in Howell v. Hamilton Meats & Provisions, Inc. (2011) 52 Cal.4th 541. The court held that an injured plaintiff's recoverable past medical damages are generally limited to the amount actually paid — the discounted rate the insurer paid — not the higher sticker amount the provider originally billed. The holding and citation should be verified with an attorney. The practical upshot: the gap between billed charges and paid amounts is real, and it's part of why lien amounts are so often negotiable.
- Billed charges are often far higher than what insurers actually pay.
- Howell v. Hamilton Meats (2011) 52 Cal.4th 541 limits recoverable past medical damages to amounts actually paid.
- The gap between billed and paid amounts is part of why lien amounts are negotiable.
Reducing the Bill
Negotiating liens down
Lien amounts are frequently reduced before a case closes. Common reasons a provider or plan may accept less include: the settlement is too small to pay everyone in full, so lienholders take a proportional cut; the original charges exceed what's reasonable for the services, echoing the Howell dynamic; statutory reductions apply, such as the Medi-Cal attorney-fee reduction; and goodwill, or the lienholder's desire to get paid promptly rather than fight. Negotiating liens is detailed, deadline-sensitive work, and the savings often go straight into your pocket. An experienced attorney does this routinely; doing it yourself is risky. If you don't yet have representation, you can browse California injury attorneys or request a free case review.

Common mistakes
Avoid these claim-planning mistakes
Search results can make a complicated injury issue feel simple. These are the mistakes that most often create confusion later.
Assuming a $100,000 settlement means $100,000 in your pocket — attorney's fees, case costs, and medical liens all come out first.
Treating MedPay like a lien — MedPay is your own insurance paying regardless of fault, not a claim against your recovery.
Assuming all provider liens work the same way — hospital liens may arise under the Hospital Lien Act, while surgeon, chiropractor, and imaging liens typically arise from a contract you signed.
Believing the inflated billed charges are what you actually owe — under the Howell rule, recoverable past medical damages are generally limited to amounts actually paid.
Trying to resolve liens yourself instead of using an attorney — lien negotiation is detailed, deadline-sensitive work where mistakes can cost you money.

FAQ
Questions this page answers
Will I owe money even if I lose my case?Open
Possibly. A lien or letter of protection is still a bill. If there's no recovery, you may still be personally responsible to the provider depending on what you signed. This is a general statement, not advice about your situation — confirm with a licensed California attorney.
Can a hospital take my whole settlement?Open
The Hospital Lien Act limits what a payer must satisfy out of your recovery to 50 percent of the money due, after prior liens. But you may still owe the balance to the hospital separately — the 50 percent figure caps the paying party's exposure, which is distinct from your underlying debt. Confirm how this applies to your case with an attorney.
Is MedPay the same as a lien?Open
No. MedPay is your own insurance paying bills regardless of fault. It's not a claim against your recovery, though your auto insurer may seek reimbursement in some situations. Whether reimbursement applies in your case should be confirmed with an attorney.
How long do I have to bring my injury claim in the first place?Open
Most California personal injury claims have a two-year deadline, but there are important exceptions. You can check the California statute of limitations calculator, and confirm your specific deadline with a licensed California attorney.
