I. The Howell Rule: Amount Paid or Incurred
Howell v. Hamilton Meats & Provisions, Inc., 52 Cal.4th 541 (2011), held that a plaintiff’s recoverable past medical damages are limited to the amount actually paid or incurred for medical treatment, not the full “billed” amount. The Supreme Court reasoned that the difference between the billed amount and the accepted amount — the “negotiated discount” — was never a real economic loss to the plaintiff.
Before Howell, the collateral source rule prohibited defendants from introducing evidence that a plaintiff’s medical bills had been paid or reduced by insurance. Howell did not eliminate the collateral source rule, but it redefined the recoverable amount itself. The key distinction: evidence that bills were paid by insurance remains inadmissible; but evidence of what the provider actually accepted as full payment is admissible because it defines the measure of damages.
II. The Pebley Lien Problem
Pebley v. Santa Clara Organics, 22 Cal.App.5th 1266 (2018), addressed a gap in Howell: what happens when the plaintiff uses a lien-based provider? Lien-based treatment — common in personal injury cases — means the provider agrees to defer payment until case resolution, typically at full billed rates. Because no insurer has negotiated a discount, the “amount incurred” is the full billed amount.
Pebley held that the collateral source rule bars defendants from arguing that the plaintiff could have used insurance instead of a lien provider. If the plaintiff chose lien-based care, the billed amount is the recoverable amount — Howell’s cap does not apply because no discount was actually given.
III. Defense Tactics to Push the Cap Lower
Fifteen years of post-Howell litigation have produced a playbook of defense strategies. The most common include:
First, Howell motions in limine to exclude the billed amount entirely, arguing that only the paid-or-accepted amount is admissible. Second, challenging lien-based billing as unreasonable, using expert testimony to argue that the lien provider’s charges exceed the “reasonable value” of services. Third, requesting Howell hearings to determine the threshold amount before the jury hears the number.
Plaintiff’s counsel must be prepared to demonstrate the reasonableness of lien-based charges, typically through treating-physician testimony or healthcare economist experts, and to invoke Pebley to protect the full billed amount in lien cases.
IV. Future Medical Damages: A Separate Analysis
Critically, Howell applies only to past medical damages. Future medical damages are measured by the reasonable value of future care, not the amount a particular insurer would negotiate. The distinction matters because defendants increasingly try to extend Howell’s logic to future damages, arguing that anticipated insurance discounts should be applied prospectively.
California courts have consistently rejected this extension. The future-damages measure remains the reasonable cost of necessary future care, which the jury determines based on expert testimony about treatment plans, life-care plans, and prevailing medical costs.
