In a California injury case, the number on your medical bill is usually not the number a jury sees. Three decisions control this. Howell v. Hamilton Meats (2011) held that a plaintiff whose care was paid by health insurance recovers the amount actually paid and accepted as full payment, not the higher amount the provider originally billed. Corenbaum v. Lampkin (2013) extended that logic and held the full billed amounts are inadmissible, not just for past medical expenses, but also as evidence of future medical costs and as a reference point for pain and suffering. Pebley v. Santa Clara Organics (2018) carved out the exception: a plaintiff who is uninsured, or who chooses to treat outside their insurance on a lien, is not held to negotiated insurance rates, and the full billed amounts can come in as evidence of the reasonable value of that care.
The practical consequence is one most people find strange the first time they hear it. Two people can suffer the same injury, receive the same surgery from the same surgeon, and have very different provable medical damages, because one of them handed over an insurance card and the other did not. That is not a loophole. It follows from what California actually compensates: Civil Code 3333 allows the amount that will compensate for the detriment caused, and Howell decided that a discount the plaintiff never had to pay is not a detriment they suffered. Understanding which side of that line your case sits on is the first thing we look at when we open a file.
Howell v. Hamilton Meats (2011)
The plaintiff in Howell was billed roughly $190,000 for her care. Her health insurer, under its negotiated contracts with the providers, paid about $60,000, and the providers accepted that as payment in full. The rest was written off.
The California Supreme Court held that she could recover the amount paid, not the amount billed. The reasoning was straightforward: an injured person recovers the reasonable value of medical care, but the recovery can never exceed what was actually incurred. Because the providers agreed by contract to accept the discounted rate, the plaintiff was never liable for the written off portion. Calling it a loss would be compensating her for money nobody spent.
The court was careful about what it was not deciding. It did not abolish the collateral source rule, which keeps a defendant from arguing that a plaintiff should recover less because someone else paid the bills. Howell is narrower: the negotiated write off was never a debt at all, so there is nothing for the collateral source rule to shield.
Corenbaum v. Lampkin (2013)
Corenbaum answered the obvious follow up question. If the full billed amount cannot be recovered as past medical expenses, can it still be shown to the jury for some other purpose?
The Court of Appeal said no, on three fronts. The full billed amounts are not admissible to prove past medical expenses. They are not admissible as a basis for an expert to project the cost of future medical care. And they are not admissible as evidence relevant to non-economic damages, meaning a plaintiff’s lawyer cannot put a $190,000 bill in front of a jury and ask it to reason from that figure toward a pain and suffering number.
That last holding is the one that changed how injury cases are actually tried. For years, the size of the medical bill functioned as an anchor. Corenbaum removed the anchor for insured plaintiffs, and moved the emphasis to what the treatment records, the treating physicians and the plaintiff’s own testimony show about the effect of the injury on a life.
Pebley v. Santa Clara Organics (2018)
Pebley involved a plaintiff who had health insurance but chose to treat with providers outside his plan, on a lien, meaning the providers agreed to be paid out of any recovery.
The Court of Appeal held that such a plaintiff is treated as uninsured for these purposes. A plaintiff is not required to use health insurance, and one who treats on a lien remains personally liable for the full billed charges, because no contract requires the provider to accept a discounted rate. On those facts, the full billed amounts are relevant evidence of the reasonable value of the services and are admissible.
Pebley did not hand plaintiffs a blank check. Reasonable value remains the measure, and the defense is entitled to challenge the amounts through its own evidence, including expert testimony about what providers in the community generally charge and accept for the same services. What Pebley established is that the lien patient gets to put the bills in front of the jury and argue their reasonableness, rather than being capped by rates negotiated by a plan they did not use.
What this means in a real case
Two paths, and the case is on one of them from the day treatment starts.
Insured treatment. Past medical damages are generally limited to amounts paid and accepted as full payment. The bills themselves stay out. The trade off is stability: the numbers are clean, defensible and hard to attack, and the case rarely gets sidetracked into a dispute over billing practices.
Lien or uninsured treatment. The full billed amounts become the evidence of reasonable value, which usually means a larger economic damages figure. The trade off is exposure: the defense will scrutinize the referral relationship between the lawyer and the providers, the rates charged, and whether the treatment was necessary. Those questions get asked in every lien case, and the answer needs to be a good one.
Neither path is right for everyone. What we tell clients is that this is a medical decision first and a legal one second. If a person has good insurance and a surgeon in network who is the appropriate doctor for the injury, they should see that surgeon. Where lien treatment genuinely makes sense is when someone has no coverage, when their plan will not authorize the care a treating physician says is necessary, or when the only specialist who can address the injury does not take the plan.
When the treatment is mixed
Most real files are not purely one or the other. Someone goes to the emergency room by ambulance and the hospital bills their health plan. Weeks later they see a chiropractor, then an orthopedist, on a lien. The result is a single case with two categories of medical damages governed by two different rules, and the presentation has to keep them separate: paid amounts for the insured portion, billed amounts supported by reasonable value evidence for the lien portion. That is ordinary and manageable. What causes trouble is a file where nobody sorted this out until the eve of trial and the records do not clearly show which providers were billed to whom.
The same care is needed with ambulance charges, emergency room facility fees and imaging, which are frequently billed by separate entities under separate arrangements. We ask for the full billing ledger from each provider, not just the summary statement, because the ledger shows what was billed, what was adjusted, what was paid and by whom. That single document answers most of the questions these three cases raise.
There is a further complication people rarely anticipate. Health insurers, Medi-Cal and Medicare generally assert a right to be reimbursed out of an injury recovery. So a plaintiff who used insurance may recover the paid amount and then owe a portion of it back through a lien or reimbursement claim, and those amounts can often be negotiated down. Working out the net result requires looking at the reimbursement side and the damages side together, not one at a time.
How these rules shape the evidence
Because the bill no longer speaks for the injury, other proof has to. In the files we handle, the medical damages presentation is built from the treating physicians rather than the billing department: what they observed, what they diagnosed, what the imaging showed, what they recommended and why, and what the person could not do afterward.
Future care follows the same rule. After Corenbaum, a life care planner or treating physician projecting future costs for an insured plaintiff cannot base the estimate on the historical billed rates. The projection has to rest on evidence of what the care will actually cost that person going forward.
This matters most in the cases where future care is the largest component: a brain injury requiring years of follow up, a spinal injury heading toward surgery, or a serious car accident where a person will need pain management indefinitely. It matters just as much in a slip and fall or a motorcycle collision where the treatment was substantial but the medical record is thin because the person stopped going.
An insurer’s letter in these cases usually says a version of the same thing: it will value your past medicals at the paid amounts, question anything above that, and quietly ignore future care. Answering that letter requires knowing which of these three cases governs your treatment and having the records that support it.
Key points
- Howell limits an insured plaintiff’s past medical damages to the amounts actually paid and accepted as full payment.
- Corenbaum keeps the full billed amounts out of evidence entirely, including for future care and as an anchor for pain and suffering.
- Pebley allows a plaintiff who is uninsured or treating on a lien to introduce the full billed amounts as evidence of reasonable value.
- The defense can still challenge the reasonableness of lien billed amounts with its own evidence.
- Health insurers, Medi-Cal and Medicare generally seek reimbursement from a recovery, so the paid amount is not always what a client keeps.
- Where the bill can no longer carry the case, the treating physicians and the treatment records have to.
Frequently asked questions
Why can’t the jury see my full medical bill?
If your care was paid by health insurance at a negotiated rate, Howell and Corenbaum treat the written off portion as an amount you never owed, so it is not a loss and the full bill is inadmissible. The jury sees the amounts actually paid instead. If you treated on a lien or had no insurance, Pebley generally allows the full billed amounts to be presented.
Should I use my health insurance or treat on a lien?
Get the right care first, and let the legal consequences follow the medical decision. Insurance usually produces cleaner, more defensible numbers but a smaller economic damages figure, while lien treatment supports a larger figure and invites scrutiny of the charges and the referral. Where a plan will not authorize necessary treatment, lien care is often the only realistic option.
Does Howell mean my case is worth less because I have insurance?
It limits the past medical expense component, which is only one part of the case. Non-economic damages, lost income, loss of earning capacity and future care are unaffected by how the past bills were paid. In practice we see cases with modest paid medicals and substantial value because the injury changed how someone lives.
Do I have to pay my health insurer back out of a settlement?
Often yes. Health plans, Medi-Cal and Medicare generally assert reimbursement or lien rights against an injury recovery, though the amounts are frequently reduced by negotiation and by rules that account for attorney fees and costs. This should be worked out before a settlement is finalized, not after.
