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.

Appellate Court Rejects Horizontal Immunity Defense to Company Not Acting as Statutory Subcontractor

The First District Court of Appeal held that a property management company was not entitled to horizontal immunity under section 440.10(1)(e), Florida Statutes, in a negligence action brought by an employee of another company working on the property. The claimant was injured while servicing a swimming pool at an apartment complex. His employer had contracted with the property owner to maintain the pool. Following the accident, the claimant received workers' compensation benefits through his employer’s carrier. The claimant subsequently filed a negligence action against the property management company, alleging that it failed to maintain the premises in a reasonably safe condition and failed to warn him of a dangerous condition that caused his injuries. The property management company had been retained by the property owner to maintain the complex in good operating condition and to perform routine maintenance and repair work. The property management company argued that it was immune from suit under section 440.10(1)(e) of Florida’s Workers’ Compensation Law. That provision grants immunity to a subcontractor providing services in conjunction with a contractor on the same project or contract work from civil actions brought by employees of another subcontractor, subject to limited exceptions. According to the property management company, it qualified as a subcontractor working on the same project as the claimant’s employer and was therefore entitled to horizontal immunity. The trial court agreed and entered summary judgment in its favor. On appeal, however, the claimant argued, and the appellate court agreed, that horizontal immunity applies only when a contractor has sublet work arising from a contractual obligation owed to a third party. The court noted that prior decisions consistently held that an entity acting solely on its own behalf as the owner of property, rather than pursuant to a contract with a third party, is not a “contractor” under section 440.10(1), even when it hires other companies to perform work on the property. In Teed, the property management company could not establish that the property owner had a primary contractual obligation to a third party to maintain either the apartment complex or the swimming pool, which it then delegated to the claimant’s employer or the property management company. As a result, the property owner did not qualify as a statutory contractor, and the property management company was not a subcontractor entitled to horizontal immunity under section 440.10(1)(e). The First District therefore reversed the lower court’s ruling and remanded the case for further proceedings on the claimant’s negligence claim.

Commonwealth Court Holds That a Claimant Who Was Struck By a Car While Crossing the Street During an Unpaid Break Was In the Course and Scope of Employment

This case involved a claim petition filed by a claimant who sustained injuries after being struck by a vehicle while crossing the street in front of the employer’s premises. The employer denied the claim based on course and scope, as the accident occurred during one of two mandatory fifteen (15) minute breaks provided to the claimant. The claimant would punch out at the beginning of a break and punch back in when the break was over.  On the date of the incident, the claimant punched out and left the building to get lunch at a restaurant, which required her to cross the employer’s parking lot, and then a public street, where the injury occurred. The Workers Compensation Judge (WCJ) dismissed the petition, noting that that during the two mandatory fifteen-minute breaks per shift allowed by the employer, the claimant was free to leave the employer’s premises, and during breaks, permitted to engage in whatever activity she desired. The WCJ found that at the time of the accident, the claimant was on her own time, in the middle of the street, and going to get lunch.   The claimant filed an appeal with the Worker’s Compensation Appeal Board (Board), and the Board reversed.  According to the Board, the claimant’s location was still on the employer’s premises, as the claimant was taking her customary route while using a reasonable ingress/egress from the employer.  Further, the Board found that the “Personal Comfort Doctrine” applied, as the claimant was on a momentary departure to take care of her personal comfort, within the window of time she was allotted for her break.  The Board remanded the case, and a WCJ granted the claim petition.  The Board affirmed, and the employer appealed to the Commonwealth Court. Before the Court, the employer argued that the claimant was not in the course and scope of her employment, because the injury did not occur on its premises, and the claimant was outside the bounds of the Personal Comfort Doctrine. The Court, however, rejected these arguments, and dismissed the employer’s appeal.  The Court noted that the break given to the claimant was so cursory, when she set out to relieve her hunger for her own personal comfort,  she remained in the course of her employment when she sustained her injuries.  A Petition for Allowance of Appeal in the Supreme Court has been filed by the Employer, Giant Eagle.
