Letters of Protection in California Injury Cases: Getting Treatment When You Cannot Pay Up Front

A letter of protection lets an injured person get needed medical care now and pay from the settlement later. It is a powerful tool — and, after Pebley and Qaadir, a contested one at trial.

After a serious injury, the medical bills start before any settlement arrives — and many injured people have no health insurance, high deductibles, or providers who will not treat an accident victim on credit. A letter of protection (LOP) bridges that gap. It is a written promise, usually signed by

A letter of protection is a practical answer to a hard problem: an injured person needs medical care, but cannot pay for it until the case that caused the injury is resolved. Under an LOP, a treating provider agrees to render care and defer billing, accepting payment from the settlement or judgment rather than demanding it up front. In exchange, the provider typically takes a lien on the recovery. For many California plaintiffs — especially the uninsured — the LOP is the only realistic path to the surgery, imaging, or specialist care their injury requires. But the device sits at the intersection of several contested areas of California damages law, and recent decisions have changed both sides of the equation.

What a Letter of Protection Is

An LOP is a written assurance, ordinarily from the plaintiff’s attorney to the medical provider, that the provider will be paid for treatment out of any recovery in the case. It usually accompanies a medical lien, by which the provider claims a right to be paid from the settlement proceeds before the client receives the balance. The arrangement is contractual: the provider agrees to wait, the patient agrees to pay from the recovery, and the attorney agrees to honor the lien when funds arrive.

The LOP should not be confused with the statutory Hospital Lien Act under Civil Code § 3045.1 and following, which gives hospitals an automatic lien on a patient’s tort recovery for emergency and ongoing services. The statutory hospital lien arises by operation of law and carries its own rules and limits. An LOP, by contrast, is a voluntary contractual arrangement that can be used by physicians, surgical centers, imaging providers, and other practitioners who are not covered by the statutory scheme. Both devices secure payment from a recovery, but they come from different sources and follow different rules.

Why LOPs Matter: Access to Care

The central benefit of an LOP is access. An injured worker without health insurance, a patient whose plan will not cover accident-related care, or a client who needs a specialist unwilling to treat on credit may have no way to get necessary treatment while the case is pending. The LOP removes the up-front payment barrier, allowing the injury to be properly diagnosed and treated rather than left to worsen while liability is litigated. Delayed or forgone treatment harms the patient medically and, not incidentally, weakens the case; prompt, documented care serves both the client’s health and the claim.

LOPs also allow a plaintiff to choose providers who will document the injury thoroughly and stand behind their treatment, rather than being limited to whatever emergency care the patient could obtain in the immediate aftermath. The trade-off is that lien-based treatment becomes a subject of dispute at trial, because defendants argue that providers who are paid from recoveries have an incentive to over-treat and over-bill. California law now addresses both the recoverable amount and that bias argument directly.

How Much Can a Plaintiff Recover? Howell and Pebley

California limits recovery of past medical expenses to the reasonable value of the services, and under Howell v. Hamilton Meats & Provisions, Inc. (2011) 52 Cal.4th 541, an insured plaintiff whose provider accepted a negotiated, discounted amount as full payment cannot recover more than that amount — the undiscounted billed charge is not recoverable because it was never incurred. Howell tied recovery to the amount actually paid and accepted for insured plaintiffs.

LOP cases are different, and the Court of Appeal addressed that difference in Pebley v. Santa Clara Organics, LLC (2018) 22 Cal.App.5th 1266. The court held that a plaintiff who has health insurance but chooses to treat outside of it on a lien basis may be treated as an uninsured plaintiff for purposes of damages. Such a plaintiff is not limited to negotiated insurance rates; instead, the jury may consider the provider’s full billed charges as evidence of the reasonable value of the care, alongside other evidence of value. Pebley recognized that a plaintiff is not obligated to use available insurance and may elect lien-based treatment, with the reasonable value of that care determined on the evidence.

The practical significance is large. Under Pebley, a plaintiff treating under an LOP can put the provider’s actual charges before the jury as evidence of reasonable value, rather than being capped at discounted insurance rates. But billed charges are evidence of reasonable value, not conclusive proof of it, and the defense is entitled to contest both the reasonableness of the charges and the credibility of the providers who set them.

The Defense Response: Bias Evidence Under Qaadir

If a plaintiff can show full billed charges, defendants want to show the jury why those charges may be inflated. In Qaadir v. Figueroa (2021) 67 Cal.App.5th 790, the Court of Appeal held that a defendant may introduce evidence relevant to the bias of lien-based treating providers and retained experts — including the financial relationship between the provider and the plaintiff’s attorney, the existence of referral arrangements, and the fact that payment depends on the plaintiff’s recovery. This evidence goes to the credibility of the providers and the reasonableness of their charges.

The authority for this is ordinary impeachment law. Under Evidence Code § 780, the jury may consider the existence or nonexistence of any bias, interest, or other motive when weighing a witness’s credibility. Qaadir applied that principle to the LOP context: a provider whose payment comes out of the very recovery the provider’s testimony helps to inflate has an interest the jury is entitled to weigh. Qaadir thus did not forbid LOP-based recovery; it ensured that the jury hears both the charges and the reasons to scrutinize them.

The result is a balanced battleground. A plaintiff who treats under an LOP can recover the reasonable value of necessary care, supported by the provider’s charges. A defendant can test that value by exposing the financial incentives behind it. The plaintiff’s best protection is treatment that is genuinely necessary, well documented, and provided by practitioners whose charges reflect the market — because that is what survives cross-examination.

Protecting the Lien and the Client

An LOP creates obligations that outlast the trial. When the case resolves, the attorney must honor the lien from the settlement proceeds, and disputes over the amount owed to lienholders are common. Providers may bill at full rates, while the net recovery may not stretch to pay every lien in full after fees and costs. Experienced counsel negotiates lien reductions, coordinates competing liens, and ensures that the client is left with a fair share of the recovery rather than seeing it consumed by medical charges.

The attorney’s duties here are serious. An LOP is a binding commitment, and failing to satisfy a valid lien from the proceeds can expose both the client and the attorney to liability. The disbursement at the end of a case must account for every lien, which is why the lien strategy should be managed from the outset rather than improvised at settlement. Done well, the LOP delivers on its promise: the client gets the care they needed and keeps a meaningful portion of the recovery.

Practical Guidance for Injured Californians

If you are injured and cannot afford treatment, an LOP may make necessary care possible, but it is not a decision to make casually. Get care that is genuinely necessary and let the providers document it fully. Understand that the charges will be scrutinized and that the defense may tell the jury how the providers are paid. Keep your own records of symptoms and treatment. And work with counsel who will manage the liens so that the arrangement protects your health without swallowing your recovery. Used correctly, the LOP is one of the most valuable tools an injured person has.

Documenting Medical Necessity to Withstand Scrutiny

Because lien-based treatment draws defense scrutiny, the single most important protection a plaintiff has is documentation of medical necessity. The defense argument — that lien providers over-treat because they are paid from recoveries — loses force when the treatment is plainly necessary, consistently documented, and consistent with the objective findings. A surgery supported by positive imaging, a referral pattern that tracks the patient’s symptoms, and contemporaneous records explaining the clinical reasoning are far harder to attack than vague notes and treatment that seems driven by litigation rather than medicine.

This is why the choice of providers matters. Practitioners who document thoroughly, order tests when the clinical picture warrants them, and can explain their decisions on cross-examination strengthen both the patient’s care and the claim. Objective diagnostic evidence — MRI and CT findings, EMG studies, surgical findings — anchors the reasonableness of the treatment in something other than the provider’s say-so. A plaintiff whose treatment is objectively grounded can meet the Qaadir bias evidence head-on: yes, the provider is paid from the recovery, but the imaging and the surgical findings confirm the care was necessary regardless.

A further point on documentation: continuity and consistency across providers carry weight. When a primary physician, an imaging center, a surgeon, and a physical therapist all describe the same injury, order tests that follow logically from one another, and record consistent findings over time, the overall treatment picture reads as genuine medicine rather than litigation-driven billing. Gaps, contradictions, or treatment that appears disconnected from the objective findings give the defense openings. A coherent, well-sequenced treatment record is itself evidence that the care was necessary and its value reasonable, and it is the plaintiff’s strongest answer to the incentive argument the defense is entitled to make.

The reasonable value of the care is a separate question from its necessity, and it too benefits from evidence. Testimony about prevailing rates for comparable services, the provider’s customary charges, and what the care would cost in the market all support the reasonableness of the billed amounts. Pebley lets the jury consider full charges, but the jury must still find them reasonable, and a record that situates the charges within the market is what sustains them.

Coordinating Multiple Liens and the Net Recovery

Serious injury cases often generate multiple liens — several treating providers, perhaps a health plan asserting reimbursement, and sometimes a statutory hospital lien under Civil Code § 3045.1 as well. When the case resolves, all of these claims look to the same pool of money, and they can easily exceed what remains after attorney fees and costs. Managing that competition is a core part of protecting the client’s recovery, and it is governed by a mix of contract, statute, and equitable principles.

The attorney’s task is to negotiate reductions and to coordinate the competing claims so the client is not left with little or nothing. Statutory hospital liens carry their own cap — generally limiting the lien to a percentage of the recovery — which constrains how much a hospital can take. Contractual LOP liens are negotiable, and providers frequently accept reductions, particularly where the recovery is modest or liability was contested. Health-plan reimbursement claims have their own rules, including made-whole and common-fund principles that can reduce what the plan recovers. Fitting these pieces together so the client retains a fair share is detailed, high-stakes work.

The worst outcome is a recovery consumed entirely by liens, leaving an injured client with nothing after paying every provider in full. Experienced counsel prevents that by planning the lien strategy from the outset, negotiating reductions before disbursement, and ensuring that the economics of the case account for the liens that lien-based treatment creates. The LOP makes care possible; disciplined lien management makes sure the client actually benefits from the recovery that care helped produce.

Frequently Asked Questions

What is a letter of protection?

A letter of protection is a written promise, usually from the plaintiff’s attorney to a medical provider, that the provider will be paid for treatment out of the eventual settlement or judgment. It lets an injured person get care now and defer payment, typically in exchange for a lien on the recovery.

How is an LOP different from a hospital lien?

A hospital lien under Civil Code § 3045.1 arises automatically by statute for hospital services. An LOP is a voluntary contractual arrangement available to physicians, surgical centers, and other providers not covered by the statute. Both secure payment from a recovery but follow different rules.

Can I use a letter of protection if I have health insurance?

Yes. Under Pebley v. Santa Clara Organics (2018) 22 Cal.App.5th 1266, an insured plaintiff may choose to treat outside insurance on a lien basis and be treated as uninsured for damages purposes, meaning the jury may consider the provider’s full billed charges as evidence of reasonable value.

How much can I recover for lien-based treatment?

You can recover the reasonable value of necessary care. For lien-based treatment, Pebley allows the provider’s full billed charges to be presented as evidence of that value, rather than being capped at negotiated insurance rates. The charges are evidence of reasonable value, not automatic proof of it.

What can the defense tell the jury about my providers?

Under Qaadir v. Figueroa (2021) 67 Cal.App.5th 790 and Evidence Code § 780, the defense may introduce evidence of the financial relationship between lien providers and the plaintiff’s attorney, referral arrangements, and the fact that payment depends on the recovery, all to challenge the providers’ credibility and the reasonableness of their charges.

Does Howell limit my recovery?

Howell v. Hamilton Meats (2011) 52 Cal.4th 541 limits an insured plaintiff to the amount actually paid and accepted when the provider took a negotiated discount. Pebley distinguishes the lien-based plaintiff who treats outside insurance, who is not confined to those negotiated rates.

What happens to the lien when my case settles?

The attorney must satisfy valid liens from the settlement proceeds. Because full charges can exceed the net recovery after fees and costs, counsel often negotiates lien reductions and coordinates competing liens so the client retains a fair share.

Is a letter of protection a good idea for my case?

It depends on your medical needs, your insurance, and your case. An LOP can provide essential access to care, but the charges will be scrutinized and the defense may expose the payment arrangement. An attorney can help you decide and manage the liens so the arrangement works in your favor.
