Limiting the Opinions of Plaintiff’s Non-Retained Expert Witnesses Regarding Injury Causation and Permanency

Defense Digest, Vol. 30, No. 1, March 2024

Key Points:

  • Plaintiff’s non-retained experts are treating physicians, and their testimony at trial should be limited to their scope of treatment, diagnosis, and prognosis with respect to the injuries alleged. 
  • Plaintiff’s treating physicians lack the proper foundation to provide expert opinion testimony on medical causation and permanency unless they take the plaintiff’s history relating to an incident and review the records of the plaintiff’s other physicians.

When a plaintiff discloses a treating physician as a non-retained medical expert, this non-retained expert’s testimony should be limited to exclude testimony regarding medical causation and permanency unless there is a proper predicate for such testimony. To lay the proper predicate, the physician must have reviewed the plaintiff’s medical records from other treating physicians, and the physician should obtain a history from the plaintiff that describes the manner in which the plaintiff was allegedly injured. 

For instance, in a slip and fall case, the history should include the manner in which the plaintiff allegedly slipped and fell. Where the treating physician fails to review the medical records from the plaintiff’s other medical providers and fails to obtain a history of how the plaintiff allegedly came to be injured, there is an argument that the non-retained expert/treating physician should be precluded from testifying about injury causation and permanency.

Pursuant to § 90.702, Fla. Stat., Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579 (1993), and other applicable Florida law, a trial court must make two preliminary factual determinations prior to permitting expert testimony: (1) whether the expert testimony will assist the trier of fact in understanding the evidence or in determining a fact in issue; and (2) whether the witness is qualified by knowledge, skill, experience, training, or education to express an opinion on the matter.

Under Daubert, the trial court is specifically assigned a gatekeeper task of ensuring that an expert’s testimony, whether scientific or non-scientific, rests on a reliable foundation and is relevant to the task at hand. Id. See also Kumho Tire Co. v. Carmichael, 526 U.S. 137, 141, 148-49 (1999); Corwin v. Walt Disney World Co., 475 F.3d 1239, 1250 (11th Cir. 2007). 

In Cooper v. Marten Transp., Ltd., 539 Fed. Appx. 963, 967 (11th Cir. 2013), the Eleventh Circuit explained that causation “could not be determined through a physical examination and the chronology of events alone.” The court further noted in that case that neither physician explained the basis for their opinions. Id. 

Courts frequently exclude causation opinion testimony of expert witnesses who base their opinions on a plaintiff’s account of the facts without consideration of other possible causes of injury. See Carmody v. State Farm Mut. Auto. Ins. Co., 2015 WL 5542534, at *3 (M.D. Fla. Sep. 18, 2015).

Moreover, even if an expert is qualified, the expert must have a sufficient factual predicate underlying those opinions. Florida Statute § 90.705(2), explicitly states: “[i]f the [opposing] party establishes prima facie evidence that the expert does not have a sufficient basis for the opinion, the opinions and inferences of the expert are inadmissible unless the party offering the testimony establishes the underlying facts or data.” 

The legislative history of the rule emphasizes that this subsection intends to provide protection for opposing counsel so that expert opinions that are completely unqualified will not be admitted and risk prejudicing the jury. See Florida Statute § 90.705, Law Revision Counsel Note (1976). “In this instance, the protection of using cross-examination to expose the flaws in the opinion is not sufficient in all cases.” Id.

In a recent slip and fall case in Broward County, Florida, the plaintiff disclosed a non-retained expert/treating physician who was a pain management specialist. This doctor had not been provided and had not otherwise reviewed any medical records regarding the plaintiff’s post-incident treatment, other than his own records. He had not obtained a history from the plaintiff of how the plaintiff had allegedly slipped and fallen or how the plaintiff was allegedly injured. In this particular case, the physician admitted in deposition that he was not retained to provide any opinion testimony regarding any permanent injury. 

The opinions of the physician regarding the plaintiff’s medical condition were based solely on subjective statements made by the plaintiff, that the alleged injuries occurred as a result of the incident (without any history of the incident itself or how the plaintiff came to be injured as a result of the incident), together with the medical treatment related to the physician’s care of the plaintiff (in a vacuum, without any medical treatment history related to the care and treatment provided by the plaintiff’s other treating physicians).
 
There was no record evidence of any attempt by the non-retained expert/treating physician to eliminate other possible causes of the plaintiff’s conditions. Additionally, there was no record evidence that this physician conducted a review of the plaintiff’s pre- or post-incident medical history. Accordingly, it was reasonable to conclude that the doctor intended to identify the condition for treatment purposes rather than to determine its exact source. See generally, Turner v. Iowa Fire Equipment, Co., 229 F.3d 1202, 1205 (8th Cir. 2000). Furthermore, none of the plaintiff’s medical records revealed information to demonstrate that the doctor made any “attempt to consider all the possible causes, or to exclude each potential cause until only one remained, or to consider which of two or more non-excludable causes was more likely to have caused the condition.” Id. at 1208 (holding that the trial court did not abuse its discretion in excluding treating physician causation opinion, based exclusively upon the medical history obtained from the plaintiff, which indicated no respiratory problems, and the temporal relationship between the incident and the onset of symptoms); see also, e.g., State, Div. of Risk Mgmt. v. Martin, 690 So.2d 651 (Fla. 1st DCA 1997) (holding that a doctor’s testimony did not constitute competent substantial evidence as to causation because it was based on speculation, made without knowledge of claimant’s relevant medical history, and based “virtually entirely” upon claimant’s false report of causal connection between the accident and a subsequent surgery); In re Paoli R. R. Yard PC’B Litigation, 35 F.3d 717 (3d Cir. 1994) (holding that for purposes of determining admissibility of expert medical testimony, part of differential diagnosis is using standard techniques to rule out alternative causes and, thus, where defendant points to a plausible alternative cause and the doctor offers no explanation for why he or she has concluded that was not the sole cause, the doctor’s methodology is unreliable); Berry v. CSX Transp. Inc., 709 So.2d 552, 571 (Fla. 1st DCA 1998) (holding that expert witness’ testimony regarding causation of a railroad employee’s malady was admissible in toxic tort litigation, as the expert employed a scientifically acceptable differential diagnosis method in an attempt to eliminate other possible causes of symptoms and his opinion was not based upon the employee’s personal history, medical records, physical examinations, and medical tests, but upon sufficient epidemiological data, facts, and personal observations); David v. Nat’l R.R. Passenger Corp., 801 So. 2d 223, 227 (Fla. 2d DCA 2001).

On the other hand, in the recent Broward County case, we argued that the defendants’ experts could opine regarding issues of causation because they actually applied standard techniques of differential diagnosis through the review of prior medical records, examinations, diagnostic films, discovery, depositions, investigation, statements, and photographs.

The Circuit Court in Broward County granted the defendants’ motion in limine to preclude causation opinions from the plaintiff’s treating non-retained physician. In our case, we had the perfect storm of the physician not having taken a history as to how the incident occurred or how the alleged injuries were caused by the incident, coupled with the plaintiff’s attorney not having provided any other treatment records to the physician, as well as the physician’s concession that he was not retained to provide an opinion on permanency. However, based on the case law, the argument to preclude opinion testimony by a treating physician as to causation and permanency should not hinge on whether the latter concession is made by the physician during deposition.

Pennsylvania Supreme Court Holds Self-Referral Prohibition Does Not Cover Prescriptions Written by Physicians with Ownership Interests in Dispensing Pharmacies

700 Pharmacy v. Bureau of Workers’ Compensation Fee Review Hearing Office (State Workers’ Insurance Fund); Nos. 97, 98, 99, 100, 101 MAP 2024; decided June 16, 2026; by Justice Mundy.   In this case, Drs. Miteswar Purewal and Shailen Jalali, treating physicians for workers’ compensation claimants, wrote prescriptions for various medications that were filled by 700 Pharmacy. The worker’s compensation insurer refused to pay for the prescriptions on the basis that they were illegal self-referrals under the Act. 700 Pharmacy subsequently filed fee review applications with The Bureau of Workers’ Compensation Medical Fee Review Office. At a fee review hearing, both physicians stipulated they had a financial interest in the pharmacy.  The physicians argued that the Anti-Referral Provision of the Act does not bar self-referrals on prescription drugs and pharmaceutical services, since the provision does not specifically identify prescription drugs. The Fee Review Hearing Officer rejected this argument and found that prescriptions for medications are prohibited under the “goods or services” language included in the provision. 700 Pharmacy appealed to the Commonwealth Court, and the court affirmed, agreeing with the Hearing Officer’s interpretation of “goods and services” as encompassing prescriptions. 700 Pharmacy appealed to the Supreme Court.  The Supreme Court reversed the decisions of the Hearing Officer and the Commonwealth Court, holding that the term “goods and services” in the Anti-Referral Provision of the Act did not include prescriptions. According to the Court, “goods and services” was not a catch-all, but simply explanatory as to the eight enumerated categories in the provision. The provision (Section 306(f.1)(3)(iii)) reads, in pertinent part: Notwithstanding any other provision of law, it is unlawful for a provider to refer a person for laboratory, physical therapy, rehabilitation, chiropractic, radiation oncology, psychometric, home infusion therapy  or diagnostic imaging, goods or services pursuant to this section if the provider has a financial interest with the person or in the entity that receives the referral. The Court said that if the General Assembly wanted to specifically include prescription drugs and pharmaceutical services in the Anti-Referral Provision, they would have done so. They pointed out that prescription drugs and pharmaceutical services were included by the legislature in Section 306 (f.1)(3)(vi) of the Act as to reimbursement, and claimed that their omission from the Anti-Referral Provision supports the conclusion that those services are not included in the Anti-Referral Provision’s self-referral prohibition.

Unanimous New Jersey Supreme Court Holds That Personal Emails of Public Employees and Officials are Subject to OPRA

In Rosetti v. Ramapo-Indian Hills Regional High School Board of Education, the New Jersey Supreme Court unanimously held that government-related emails, which are contained within personal email accounts, are government records under the Open Public Records Act (OPRA), and a log of those emails must be produced when requested. In reaching this decision, the court conducted an analysis of the OPRA and cited previous cases that held that emails do in fact fall within OPRA’s definition of a record and must be produced when requested pursuant to the Act. The court in Rosetti then had to answer the question as to whether public officials’ personal email accounts that are used for government purposes are subject to OPRA, and found that they are. Rosetti made an OPRA request to the Board of Education seeking email logs from Board members’ personal email accounts. The Board refused to produce the logs and indicated that it was not under any obligation to produce personal email account logs, only from government-related email accounts. The issue was whether a log had to be produced for Board members’ personal email accounts, which they used to conduct Board business. The Board argued that while it was possible to create a log for government-related email accounts through its IT Department, it was not possible to do so for personal email accounts. The court rejected this argument and ruled that Board members are required to search their personal email accounts and create a log of government-related emails housed in those accounts. Once completed, each Board member then must submit a certification detailing the searches that were conducted. The court went one step further with a suggestion to government employees and officials, stating, “[g]overnment agencies should strongly advise their employees, elected officials, and others engaged in government-related business to refrain from using their personal email accounts when conducting government-related business.”  Please do not hesitate to contact me with any questions regarding this case and others pertaining to the OPRA.

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.

Coverage Determined, Judgment Paid, Bad Faith Survives: Fourth DCA’s Opinion Highlights the Distinction Between Contractual and Extra-Contractual Damages

In Healthy Food Experts, LLC v. Amguard Ins. Co., No. 4D2025-0181 (4th DCA June 10, 2026), the Fourth District Court of Appeal explained that an insurer’s payment of a judgment in a breach of contract case does not automatically eliminate a later bad faith claim seeking extra-contractual damages. The decision provides guidance on when a first-party bad faith claim may still proceed after a coverage dispute has already been resolved by a judgment. Healthy Food Experts, LLC involved a dispute related to a property damage claim submitted under a commercial insurance policy issued by the insurer following a ceiling collapse at the insured’s restaurant. The insurer denied coverage for the insured’s losses for business personal property and business income, but extended coverage for the food spoilage losses. As a result, the insured filed a breach of contract action and ultimately obtained a jury verdict. The insurer appealed the verdict and, while the appeal was pending, the insured filed a Civil Remedy Notice (CRN) seeking payment for the judgment plus interest. The insurer failed to cure the CRN within the statutory sixty-day cure period, but paid the judgement in full with accrued interest following the appeals court’s per curiam affirmance. Nevertheless, the insured filed a first party bad faith lawsuit claiming to have suffered extra-contractual damages. In response to the bad faith suit, the insurer filed a Motion to Dismiss for failure to state a cause of action, relying on Fridman v. Safeco Insurance Co. of Illinois, 185 So. 3d 1214 (Fla. 2016) stating that damages were fixed by judgment of the breach of contract suit and the insured could not recover additional damages beyond those already awarded. The insurer also argued that the judgment did not exceed the insured’s policy limits, which was a required element of a first party bad faith claim. The trial court dismissed the bad faith action based on Fridman, concluding the insured could not seek any additional damages.  The insured appealed the court’s ruling to the Fourth DCA arguing the trial court’s order conflicts with Florida law and misapplies Fridman, as a contractual damage determination in the underlying suit establishes the “condition precedent to prosecute a first party bad faith action.” Cingari v. First Protective Ins. Co., 377 So. 3d 1169, 1174 (Fla. 4th DCA 2024). Further, the insured argued that the only purpose to the binding language in Fridman is to prevent the re-litigating of the same damages, which in this case are the contractual damages. The insured asserted the damages were not the “same” as they were seeking consequential damages from the insurer’s alleged bad faith. The Fourth District emphasized in its ruling that a first party bad faith claim is not ripe for litigation until there has been the following: a determination of the insurer’s liability for coverage; a determination of the extent of the insured’s contractual damages, and the required civil remedy notice is filed pursuant to §624.155(3)(a).  Demase v. State Farm Fla. Ins. Co., 239 So. 3d 218, 221 (Fla. 5th DCA 2018) The court concluded that the necessary conditions were satisfied as the jury verdict determined both coverage and the extent of the insured’s contractual damages, and the insured properly filed a civil remedy notice, so the bad faith claim was ripe for litigation. The Fourth DCA further explained the insured could not seek contractual damages in its bad faith action, which was previously litigated in its breach of contract suit. However, the court determined the insured could seek “extra-contractual damages,” which were not recoverable in the insured’s breach of contract suit, which may include interest, court cost, and reasonable attorney’s fees incurred by the insured. Further, the court held excess judgment is not essential in a first party bad faith claim and the insurer’s late payment of the judgment did not preclude the insured’s bad faith action. As a result, the Fourth District Court of Appeals reversed the trial court’s final dismissal order of the bad faith action. This opinion highlights the distinction between contractual and extra-contractual damages. Moreover, this case demonstrates that a judgment does not necessarily end the dispute in a first party property claim as it is could also serve as a prerequisite of a bad faith action. The decision serves as a reminder that insurers may face bad faith exposure notwithstanding the payment of a judgment in an underlying breach of contract action.
