Billed vs. Paid Medical Damages

Measuring Past Medical Expenses When Providers Accepted Negotiated Insurance Rates Below Billed Charges

Courts divide over whether the measure of past medical damages is what providers billed or what they accepted as full payment. 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" Howell v. Hamilton Meats & Provisions, Inc., 52 Cal. 4th 541 (Cal. 2011). The negotiated rate differential, in the court’s view, is not a benefit the collateral source rule protects: the rule "precludes certain deductions against otherwise recoverable damages, but does not expand the scope of economic damages to include expenses the plaintiff never incurred." The holding carries an evidentiary corollary — "[w]here the provider has, by prior agreement, accepted less than a billed amount as full payment, evidence of the full billed amount is not itself relevant on the issue of past medical expenses," while "[e]vidence that such payments were made in whole or in part by an insurer remains, however, generally inadmissible under the evidentiary aspect of the collateral source rule."

The Utah Supreme Court adopted the same measure in 2025 as a matter of first impression. Gardner v. Norman, 2025 UT 47 (Utah 2025) held that "the collateral source rule does not require exclusion of the negotiated charges for Gardner's medical care" because "[t]he gross charge does not reflect Gardner's past medical expenses because neither he nor his insurance were ever obligated to pay that amount"; instead, "the amount of the negotiated charge reflects the actual loss incurred, which is the measure of special damages." The court stressed that its holding leaves the rule’s evidentiary protection intact — "evidence that an insurer paid any portion of the medical costs a plaintiff incurred is inadmissible" — and declined to hold gross charges categorically inadmissible: where the reasonableness of the negotiated charge is disputed they may be relevant, though "the risk of prejudice might substantially outweigh the probative value of that evidence," especially if admission risks revealing insurance coverage.

Texas reaches the paid-or-incurred result by statute. Tex. Civ. Prac. & Rem. Code § 41.0105 provides that "[i]n addition to any other limitation under law, recovery of medical or health care expenses incurred is limited to the amount actually paid or incurred by or on behalf of the claimant." Construing that language, Haygood v. De Escabedo, 356 S.W.3d 390 (Tex. 2011) held that "section 41.0105 limits a claimant’s recovery of medical expenses to those which have been or must be paid by or for the claimant" and extended the limit to the proof: "[s]ince a claimant is not entitled to recover medical charges that a provider is not entitled to be paid, evidence of such charges is irrelevant to the issue of damages." The court answered the collateral-source objection directly — "[t]o impose liability for medical expenses that a health care provider is not entitled to charge does not prevent a windfall to a tortfeasor; it creates one for a claimant" — while confirming that "the collateral source rule continues to apply to such expenses, and the jury should not be told that they will be covered in whole or in part by insurance. Nor should the jury be told that a health care provider adjusted its charges because of insurance."

Reasonable-value jurisdictions reach the opposite result by treating the write-off itself as a collateral benefit. Dedmon v. Steelman, 535 S.W.3d 431 (Tenn. 2017) held that "the collateral source rule applies in this personal injury case, in which the collateral benefit at issue is private insurance," so plaintiffs may submit the injured party’s "full, undiscounted medical bills as proof of reasonable medical expenses" while defendants are "precluded from submitting evidence of discounted rates accepted by medical providers from the insurer" to rebut their reasonableness; the value of reasonable medical expenses "is a fact question to be decided by the trier of fact." West Virginia agrees that "[w]here a person’s health care provider agrees to reduce, discount or write off a portion of the person’s medical bill, the collateral source rule permits the person to recover the entire reasonable value of the medical services necessarily required by the injury," because "[t]hose amounts written off are as much of a benefit for which the plaintiff paid consideration as are the actual cash payments made by his health insurer to the health care providers" Kenney v. Liston, 760 S.E.2d 434 (W. Va. 2014). In those states the recovery "is for the reasonable value of the services and not for the expenditures actually made or obligations incurred."

The measure of past medical damages therefore turns on how a jurisdiction characterizes the negotiated rate differential. Where courts treat the differential as an expense the plaintiff never incurred — California and Utah by common-law reasoning, Texas by the paid-or-incurred statute — recovery is capped at the amount providers accepted as full payment, and billed charges the provider had no right to collect are irrelevant to past medical expenses, an exclusion that rests on the definition of economic loss rather than on any curtailment of the collateral source rule. Where courts treat the write-off as a collateral benefit purchased with the plaintiff’s premiums — Tennessee and West Virginia — the full, undiscounted bill is admissible as evidence of reasonable value, the discount cannot reduce the award, and the defendant may not introduce the negotiated rates to rebut it. Both camps preserve the evidentiary core of the rule: whatever the measure, the jury is not told that an insurer paid any portion of the plaintiff’s medical costs or that providers adjusted their charges because of insurance.
