Overcoming the Daubert Challenge With Your Billing and Coding Expert

Defense Digest, Vol. 30, No. 3, September 2024

Key Points:

  • The Florida Standard Jury Instructions pertaining to plaintiff’s medical expenses instruct the jury to consider and award damages for the reasonable value or expense of medical care and treatment necessarily or reasonably obtained by plaintiff in the past or future. 
  • It is plaintiff’s burden at trial to prove the reasonableness of his or her medical expenses. Once he or she testifies to the amount of the medical bills and introduces them into evidence, it is a jury question whether the bills and charges represent reasonable and necessary medical expenses. 
  • If scientific technical or other specialized knowledge will assist the trier of fact in understanding the evidence or in determining a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education may testify about it in the form of an opinion or otherwise, if: the testimony is based on sufficient facts or data; the testimony is the product of reliable principles and methods; and the witness has applied the principles and methods reliably to the facts of the case.

In a recent slip and fall case we handled in Broward County, Florida, the plaintiff moved to strike a retail store’s billing and coding expert under Daubert from testifying at trial as to the usual, customary, and reasonable charges of the plaintiff’s medical-related expenses. Among other things, the plaintiff alleged the billing and coding expert relied on incomplete, unverifiable information, including her own opinion testimony, which the plaintiff averred would only confuse the jury.

In opposition, we argued the billing and coding expert had sufficient specialized knowledge, experience, and training and was adequately qualified to express her expert opinions regarding the plaintiff’s medical bills and how those bills compare to the prevailing and customary rates charged in the medical community and specific geographical location where the services were performed and that such testimony would assist the trier of fact in understanding the evidence related to those reasonable charges for the alleged treatment provided to the plaintiff. 

The plaintiff’s position would make it impossible for a defendant to contest whether the charges claimed are usual, customary, and reasonable. It would also be contrary to Florida law, which acknowledges a defendant’s right in personal injury litigation to argue to a jury that a plaintiff’s medical bills are unreasonable. See e.g., Katzman v. Rediron Fabrication, Inc., 76 So. 3d 1060, 1065 (Fla. 4th DCA 2011) (sufficiently explained below why certain hospital billing information was necessary as part of determining whether a treating doctor billed non-litigation patients at a lower rate for the same medical services is “admissible evidence regarding the reasonableness of medical expenses”); Giacalone v. Helen Ellis Mem'l Hosp. Found., Inc., 8 So. 3d 1232, 1235 (Fla. 2d DCA 2009) (stating that reasonableness of bills can be determined by looking at: (1) the relevant market for services, including the rates charged by other similarly situated providers for similar services; (2) the usual and customary rate the provider charges and receives for its services; and (3) the provider's internal cost structure). 

The plaintiff in our case also argued that the medical and billing coding expert did not employ a sufficiently reliable scientific methodology in forming the basis for her expert opinion. In pertinent part, the plaintiff cited testimony from the expert that, as part of her methodology, she would input data from the medical billing charges (CPT coding) into a nationally recognized data base in order to obtain what the usual, customary, and reasonable charges were, in her expert opinion, for the plaintiff’s medical treatment. This method, according to the plaintiff, was not sufficiently reliable under Daubert and was, therefore, inadmissible. Simply inputting data into a database, according to the plaintiff, does not survive Daubert.

In response, we cited Cordero v. Target Corporation, 2019 WL 13080580 (2019), where the federal court had already spoken on the same legal challenge under Rule 702 of the Federal Rules of Evidence as it relates to the admissibility of expert opinion testimony from a medical and billing coding expert. 

The Cordero court held that the medical billing and coding expert who specifically utilized the Context 4 Healthcare UCR database—the exact same database used by the billing and coding expert in our case—was qualified to render expert opinions on the reasonableness of the medical charges based on, among other things, the expert’s nine years of experience in reviewing the reasonableness of medical charges and nearly thirteen years of experience in establishing and reviewing “fee schedules using standards such as UCR databases and negotiating out-of-network reimbursement amounts (based on UCR data and commercial insurance allowable fees.” Id. at 23-24.

In applying Cordero and Daubert to our case, we referred the court to the testimony of our billing and coding expert, who testified at length as to the methodology utilized to determine the reasonable value of past medical bills uniformly employed by medical billing professionals based on proper CPT coding for the medical services performed, together with the sources and data obtained, which, in her expert opinion, were not arbitrary. It was further argued that our expert utilized the same methodology throughout her 30 years in the medical billing and coding industry. 

Our expert relied on nationally recognized medical billing and coding standards, federal regulations, and geographically specific modifiers based on the particular categories of medical care. The expert’s methodology was “based on billing rules and coding standards that dictate how medical services are billing in the United States, which are federally regulated, and the application of pricing databases specific to the category of care, community and year in which the service was provided.” As part of her methodology, as indicated above, the billing and coding expert utilized the nationally recognized and generally accepted UCR database (Context 4 Health Care) to review, analyze, and determine what the UCR charges should have been for the medical treatment and services provided to the plaintiff.
 
Additionally, our expert testified that she reviewed the plaintiff’s medical records and billing, including a review and verification of the CPT codes inputted by the providers, to determine if the providers listed and billed the services under the correct CPT codes. In essence, the methodology employed in our case was the same methodology utilized by thousands of medical providers throughout the United States inasmuch as those same or similar databases were used to establish and implement their fee schedules. 

Overall, we were able to successfully establish that our medical and billing coding expert relied on sufficient and reliable data, the testimony was based on reliable and verifiable methods, and the expert applied those nationally recognized scientific methods to the facts of our case. 

As a consequence, the Circuit Court denied the plaintiff’s motion in its entirety and ruled that our medical and billing coding expert was permitted to testify at trial and to provide expert opinion testimony on what the usual, reasonable, and customary charges should be for the plaintiff’s medical treatment and related expenses. The court’s decision led to a favorable settlement of the litigation shortly thereafter.

No-Cause Jury Verdict Secured in Wrongful Death Trial

We successfully obtained a no-cause jury verdict in a 13-day wrongful death trial. The decedent, a 59-year-old man, was admitted to the emergency room on February 15, 2019, with complaints of abdominal pain, decreased appetite, and constipation, despite the use of laxatives. The patient did not complain of any nausea, vomiting, or diarrhea. He had a significant medical history including diabetes, hypertension, prior coronary artery stenting, morbid obesity (with past gastric bypass surgery), longstanding ventral hernia, and back pain. A CT scan revealed multiple hernias and a potential closed-loop bowel obstruction, leading to a surgery consultation. Our client, an emergency general surgeon, interpreted that the patient did not have a closed loop or any significant obstruction and recommended non-surgical management. The patient was approved to have clear liquids, and had a vomiting incident shortly after, but our client was not notified. The patient was returned to NPO status, and after improving overnight, he was returned to “clears” and additional medical and renal consults were ordered. Our client did not receive any communications from the residents/nurses of any changes in the patient’s condition. On February 18, 2019, two rapid responses were called due to increased heart rate and vomiting. It is believed that the vomiting resulted in aspiration, causing sepsis, ultimately leading to the patient’s death. During the trial, the plaintiff’s sole medical expert highlighted imaging on the wrong hernia, which called into question all of his opinions in the case. We made key objections related to the expert testimony, limiting what the allegations were, and preventing new allegations from being made. After approximately two and a half hours of deliberating, the jury returned a no-cause verdict.

Featured Conversations... Key Takeaways from A.M. Best’s Webinar on the Misuse Defense in Product Liability Claims, Featuring Michael Salvati

Michael Salvati, shareholder in our Philadelphia office, was a panelist for the April A.M. Best webinar, “The Misuse Defense: Strategic Approaches to Defending Product Liability Claims for Insurers.” During the program, Michael and his fellow panelists offered practical, jurisdiction‑specific guidance on how misuse and failure‑to‑warn theories intersect in modern product liability litigation. Michael emphasized the unique challenges these claims present—particularly in states like Pennsylvania, where evidentiary rules diverge sharply from those applied in many other jurisdictions. Failure to Warn as the “Flip Side” of Misuse Salvati explained that failure‑to‑warn allegations often arise as a direct counter to a misuse defense. As he noted, “If our misuse defense is that the plaintiff didn't use a product properly or safely, then the failure to warn claim is that we didn't tell them how to use it properly.” He emphasized that these claims can stem from either the absence of warnings or criticisms of existing warnings, such as insufficient specificity or lack of clarity about risks. Pennsylvania’s Unique Evidentiary Landscape One of Salvati’s most notable points was the stark difference in how Pennsylvania treats evidence of compliance with industry standards. He highlighted that Pennsylvania is “one of the only states…where that evidence is not admissible” in strict liability cases. Manufacturers cannot rely on compliance with ANSI, UL, ISO, or even federal safety standards to defend the product against a strict liability claim—because the focus is solely on the product itself, not the manufacturer’s conduct. Salvati acknowledged the challenge this creates for defense counsel and clients who expect such compliance to carry weight. Understanding the Three Defect Theories Salvati also walked through the three primary defect theories recognized in many jurisdictions: - Design defect – a flaw in the product’s intended design - Manufacturing defect – a deviation affecting a specific unit - Failure to warn – inadequate instructions or warnings He noted that warnings claims are increasingly significant and sometimes stand alone when design or manufacturing theories are weak. As he put it, plaintiffs often default to warnings claims because “the default position seems to be, ‘If I got hurt, there must be something wrong.’” Warranties and State‑by‑State Variations Salvati addressed how breach‑of‑warranty claims fit into the broader framework, explaining that implied warranties—such as merchantability—often overlap with strict liability in Pennsylvania. He emphasized the importance of understanding local nuances, as warranty law and admissibility rules vary widely across states. Looking Ahead: The Growing Importance of Warnings In his closing remarks, Salvati stressed that warnings should never be treated as an afterthought in product liability defense. He observed that warnings‑only claims are becoming more common and urged manufacturers and insurers to continually evaluate the clarity and completeness of their instructions and warnings. His takeaway: “We should always be talking about what are the instructions that come with our products…to bolster a misuse defense.” Listen to the complete webinar here: https://www3.ambest.com/conferences/events/eventregister.aspx?event_id=WEB1074.

The Enforceability of Online Arbitration Agreements Remains Unresolved in Pennsylvania, But the Pennsylvania Superior Court has Provided Substantive Guidance on the Issue

Key Points: The Pennsylvania Supreme Court confirms that an order compelling arbitration is not immediately appealable as collateral orders. The outcome of Chilutti II has generally left the substantive enforceability issues with browsewrap agreements unresolved in Pennsylvania. Until this issue is resolved by the Pennsylvania courts, companies operating in the Commonwealth should strive to ensure that their registration websites and/or application screens conspicuously present arbitration agreements in manners which ensure their users and consumers assent to the terms of the agreements by following the standards set forth in Chilutti I. Browsewrap agreements have been defined as agreements “‘in which a website offers terms that are disclosed only through a hyperlink and the user supposedly manifests assent to those terms simply by continuing to use the website,’ and typically do not require an electronic signature.” See, Cobb v. Tesla, Inc., 2026 WL 458470, at *1 n. 2 (Pa. Super. Feb. 18, 2026) (citation omitted). They are largely regarded as the “if you keep using this, you agree to everything buried in this link” terms embedded into almost every online agreement consumers and users sign before proceeding with purchases of goods and/or services. While consumers are generally aware of them, many almost never click on the link, nor read them in their entirety. This leaves many consumers and users ignorant of the terms and impact of such agreements. However, one’s ignorance of the otherwise neatly-tucked-away terms rarely renders them unenforceable. The issue of the enforceability of browsewrap agreements has been up for debate for some time in many jurisdictions, including Pennsylvania. Indeed, Pennsylvania had a brief grip on this issue for a period in time. Specifically, in 2023, an en banc Superior Court set forth heightened standards for companies to meet in order to secure assent and enforce browsewrap arbitration agreements. See Chilutti v. Uber Techs., Inc., 300 A.3d 430 (Pa.Super. 2023) (en banc) (“Chilutti I”) Chilutti I involved a husband and wife who sued Uber and its subsidiaries after the wife, a wheelchair bound passenger using Uber’s rideshare service, fell, struck her head, and lost consciousness due to her uber driver failing to provide a seatbelt and making an aggressive turn during the trip. The Chilutti’s filed a negligence lawsuit against Uber and its subsidiaries. In response, the defendants moved to compel arbitration, arguing that “the couple’s conduct on the company’s website and application — when they registered for the ridesharing service — signified that they agreed to be bound by the mandatory arbitration provision found in the hyperlinked terms and conditions.” The trial court granted the defendants’ petition and stayed the proceedings pending the results of arbitration, and the Chilutti’s appealed. On appeal, the Superior Court addressed two issues. First, it addressed the issue of whether it had jurisdiction to hear the appeal. A divided Superior Court determined that it did, with its basis for the holding being that the order from which the Chilutti’s appealed was a collateral order. Next, the Superior Court set out to address the merits of the Chilutti’s substantive claim. The Superior Court concluded that the parties lacked a valid agreement to arbitrate. Its rationale was that Uber’s website and application did not provide reasonably conspicuous notice of the terms to the Chiluttis. In reaching this decision, the en banc Superior Court held that browsewrap arbitration agreements are enforceable in Pennsylvania only if the registration website and application screens explicitly inform consumers that they are waiving the right to a jury trial, the registration process cannot be completed until the consumer is fully informed of this waiver, and, when the agreement is available via hyperlink, the waiver appears at the top of the first page of the terms in bold, capitalized text. Since the ruling, Pennsylvania courts have applied Chilutti I to determine if browsewrap agreements are enforceable.  For instance, the Allegheny County Court of Common Pleas invoked Chilutti I to reject an agreement that lacked an express jury-trial waiver on the assent screen.  See Miller v. Festival Fun Parks, LLC, 92 WDA 2025 (C.P. Alleg. Cnty. Mar. 24, 2025). Similarly, the Superior Court has held that notice which failed to explicitly state the consumer was waiving a jury-trial right did not “me[e]t the strict burden set forth by our en banc Court in Chilutti I.” Pierce v. FloatMe Corp., 348 A.3d 1077, 1088 (Pa. Super. 2025). While the issue of enforceability of browsewrap agreements appeared to have been resolved by Chilutti I, Pennsylvania courts’ grip on this issue has been slackened by the Pennsylvania Supreme Court’s January 21, 2026, opinion in Chilutti II. See Chilutti v. Uber Techs., Inc., 349 A.3d 826 (Pa. 2026) (“Chilutti II”). Therein, the Supreme Court did not address the merits of the Chiluttis’ substantive claim, but rather the issue of whether the Superior Court had appellate jurisdiction to immediately review the orders staying litigation pending arbitration. The Court ultimately vacated the en banc opinion on jurisdictional grounds, holding that the Superior Court did not have appellate jurisdiction because the trial court’s order from which the Chiluttis appealed did not qualify as a collateral order and, thus, the Superior Court erred in holding to the contrary and lacked jurisdiction to entertain the merits” of the Chiluttis’ substantive claim. As such, Chilutti II has rendered Chilutti I nonbinding, and the issue of enforceability of online arbitration agreements remains unresolved. However, in light of the fact the Supreme Court did not address or comment on the merits of the Chiluttis’ appeal, Chilutti I is still meaningful. Specifically, it provides guidance as to the standards a company should strive to meet to ensure they have obtained users’ assent so that they are able to enforce online arbitration agreements. Additionally, it may serve as persuasive authority in judges’ evaluations of petitions and/or motions to compel browsewrap arbitration agreements until this particular issue is properly put before our appellate courts.
