California does not determine the reasonable value of noncontracted emergency medical services from a hospital’s billed charges, a plan’s unilateral payment methodology, or any single benchmark. The governing question is market value: the amount a willing buyer would pay and a willing seller would accept in an arm’s-length transaction. Three published decisions define the modern framework.
Children’s Hospital establishes the market approach
In Children’s Hospital Central California v. Blue Cross of California, 226 Cal. App. 4th 1260, 1274–78 (2014), the Court of Appeal held that the factors in California Code of Regulations, title 28, section 1300.71(a)(3)(B) are minimum claims-payment criteria—not an exclusive damages formula for a later civil action.
The provider bears the burden of proving reasonable value. Relevant evidence includes the full range of amounts the provider charges and accepts for comparable services, including negotiated and government rates when they reflect useful market information. Billed charges are relevant, but they are not dispositive because they represent a unilateral asking price and are rarely paid in full. The court also rejected a cost-plus theory: quantum meruit measures the value of the services to the recipient, not the provider’s internal cost of delivering them.

Long Beach Memorial emphasizes actual transactions
Long Beach Memorial Medical Center v. Kaiser Foundation Health Plan, Inc., 71 Cal. App. 5th 323, 344–46 (2021), applied the same willing-buyer/willing-seller framework after a trial in which the jury found that Kaiser’s payments equaled or exceeded reasonable value.
The decision confirms that courts may consider a broad record of actual market transactions: contracted health-plan rates, rental-network rates, government payments, cash-pay amounts, billed charges, and other comparable evidence. It also illustrates the limits of adjustments to negotiated rates. A party may argue that a contract conveys steerage, marketing, volume, or other collateral benefits, but those asserted benefits must be proved; they do not automatically justify an out-of-network premium. A plan’s internal payment methodology likewise has, at most, marginal relevance compared with amounts actually offered and accepted in the market.

Pomona Valley adds two important clarifications
In Pomona Valley Hospital Medical Center v. Kaiser Foundation Health Plan, Inc., Nos. B337963 & B339448 (Cal. Ct. App. Mar. 12, 2026), the Court of Appeal distinguished the plan’s initial regulatory valuation from the separate quantum meruit valuation decided in court. A contractual provision restricting use of an expired agreement for regulatory payment calculations did not prevent the jury from considering the parties’ prior contract in the common-law action.
The prior agreement was relevant because it reflected an actual transaction between the same market participants for the same general services. The court also upheld a fact-intensive expert analysis that grouped market data, evaluated comparability, and accounted for claimed differences in network benefits. Disagreements about weighting and adjustments generally went to cross-examination and the weight of the evidence rather than categorical exclusion. The court reaffirmed that overall costs and profits are not the measure of market value and held that prejudgment interest on the quantum meruit recovery was seven percent.

Practical implications
A persuasive valuation record should be claim-specific and transaction-based. Parties should develop the full payment distribution, identify which comparators involve genuinely similar services and market conditions, explain any adjustments for volume or network benefits, and separate regulatory compliance evidence from the ultimate quantum meruit measure.
Neither side should expect a single percentage of charges to control. The strongest case explains why selected transactions reflect—or fail to reflect—the price that informed, uncoerced market participants would have negotiated for the services at issue.
