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.

Commonwealth Court Reaffirms the Constitutionality of Act 111's IRE Provisions

In this case, the claimant sustained a work injury of January 6, 1994, which was acknowledged by Notice of Compensation Payable (NCP). After the claimant’s receipt of 104 weeks of temporary total disability benefits, the employer filed a Request for an Impairment Rating Examination (IRE). The IRE was performed in May 2023 and the IRE physician found that the claimant had a 5% whole person impairment, under the AMA Guides. The employer filed a Petition based on the IRE results, and the Petition was granted by the WCJ. During litigation, the claimant argued that the IRE provisions of Act 111 (Section 306(a.3) of the Act) were not applicable to her injury, since it predated June 24, 1996, the date Act 57 went into effect, and that the IRE provisions were unconstitutional. The Workers’ Compensation Judge (WCJ)) granted the Petition and the Board affirmed. On appeal to the Commonwealth Court, the claimant argued that Act 111 violated the nondelegation doctrine and that its retroactive application to the claimant’s injury was unconstitutional. The court rejected the arguments on the basis that they had already found the same arguments without merit in multiple, prior cases. The court also addressed an argument made by the claimant that Act 111 was procedurally defective under the Pennsylvania Constitution because it was only considered on two days in each House after having undergone amendments and reassignments. The court noted that the Pennsylvania Constitution requires every bill to be considered on three different days in each House. The claimant maintained that, according to the legislative history, the bill did not receive three separate days of consideration from each House when it was assigned a new bill number. The court pointed out, however, that the bill number, H.B. 1840 remained constant and was considered on three occasions by the House. Further, the court concluded that minor amendments to the bill were germane to its original subject, which was to modify the Act’s IRE process, in accordance with Protz II.

WCJ Improperly Refused to Conduct C&R Hearing and Erroneously Required Settlement of All Pending Petitions

In this case, the claimant sustained injuries in the course and scope of her employment as a registered nurse. The employer acknowledged the injury by a Notice of Compensation Payable (NCP).  Subsequently, a Workers’ Compensation Judge (WCJ) expanded the description of injury. The employer then filed a Termination Petition, alleging the claimant was fully recovered from the injuries. Providers filed Utilization Review (UR) Petitions, challenging UR determinations finding their chiropractic treatment to be not reasonable and necessary. A settlement of the claim was eventually reached, and the employer filed a Petition to Seek Approval of a Compromise and Release (C&R) Agreement. The C&R outlined that the agreement fully resolved all future workers’ compensation claims except for the termination and UR Petitions. Briefs were filed and one day later, the WCJ issued an Interlocutory Order which stated if instructions were not followed regarding filing of a C&R, a settlement hearing date would not be given. The employer complied with the order, and filed the C&R. Subsequently, the WCJ notified the parties that the C&R must resolve all issues in the petitions, or would not be entertained. A settlement hearing was never held, and the WCJ then issued a decision, granting the Termination Petition and dismissing the UR Petitions. The WCJ also said that the Petition for Approval of a C&R was dismissed without prejudice, as the issues in the Termination and UR Petitions went to a decision. The claimant appealed to the Workers’ Compensation Appeal Board (Board). The Board granted the claimant’s appeal, finding that the WCJ violated the requirement of Section 449 that an expedited hearing be held when a Petition for Approval of a C&R is filed.  The Board further held that it was legally incorrect for the WCJ to insist that the C&R resolve all issues raised by the pending Petitions. The Board remanded the case to a new WCJ, and Employer appealed to the Commonwealth Court. The court affirmed the Board and held that the WCJ erred, as a matter of law, by refusing to hold an expedited hearing within 30 days, once the Petition for Approval of a C&R was filed.  The court noted that the language of Section 449(b) is mandatory, and a settlement hearing is not discretionary or dependent on a party’s separate request for a stay, or whether the record has been closed. The court further rejected Employer’s argument that the case should not be remanded to a new WCJ for a new decision on the termination and and UR Petitions, as the Board passed no judgment on whether the C&R Agreement resolved the termination and UR Petitions, and left it for the WCJ to decide in connection with the Petition for Approval of a C&R.

Appellate Division Reversed Trial Judge's Orders Granting a Plaintiff's Section 40 Summary Judgement Motion

In Haskins v. Casey, et al., the plaintiff Dane Haskins worked for defendant Ekornes, Inc. (Ekornes) as a material handler. In June 2021, he filed a workers’ compensation claim petition for benefits due to a left shoulder injury in December 2020. He then resolved his workers’ compensation claim in November 2022 under an Order Approving Settlement. In January 2023, he filed a lawsuit against Ekornes and later amended to add additional claims and name other defendants, including the Ekornes president, chief financial officer, and director of human resources. In May 2025, a second amended complaint alleged that after he filed the workers compensation claim, Ekornes placed him on leave under the Family and Medical Leave Act (FMLA), denied his request for a work accommodation, and ultimately terminated him from employment in December 2021. He pleaded several causes of action asserting violations of the New Jersey Law Against Discrimination (LAD) as well as fraudulent concealment and wrongful discharge. The plaintiff then moved for partial summary judgment, seeking an order enforcing Section 40 of the Workers’ Compensation Act (WCA) as well as summary judgment on his FMLA claims. The defendants opposed the motions and cross-moved for summary judgment on the FMLA claims. After arguments, the court entered an order in December 2025, denying the FMLA motion and cross motion and granting the plaintiff’s Section 40 motion. In the order, the court permitted the plaintiff to pursue compensatory damages at trial in connection with the bodily injury claim. The court also allowed the plaintiff to present evidence of any workers’ compensation benefits to support his claim. The court then denied the defendant's subsequent reconsideration motion in February 2026. The defendants that appealed the Section 40 aspect of the orders. In reviewing the appeal de novo, the Appellate Division rejected the plaintiff's argument that the work-related injury arose out of his discrimination claims under the LAD. The plaintiff argued that he should be able to pursue a personal injury claim as a part of his LAD claim, noting that the employer’s compensation carrier would be able to assert a lien against any recovery against his LAD claims. In distinguishing between the Richter vs. Oakland Board of Education, 246 N.J. 507 (2021) case, in which the Court found that any recovery would be subject to a Section 40 lien as the allegation was that the defendants failed to accommodate her pre-existing diabetic condition, which resulted in bodily injury. In this case, the Appellate Division indicated that there was no bodily injury caused by Ekornes’ failure to accommodate a pre-existing disability. Rather, the shoulder injury was a result of a workers compensation claim, for which he received appropriate benefits previously. The Appellate Division noted that if the plaintiff was successful in proving his LAD claims, he would be entitled to damages caused by the discriminatory discriminatory conduct such as lost wages and emotional distress damages and that there will be no Section 40 lien. In addition, the Appellate Division disagreed that the petitioner could present evidence about and seek damages for his shoulder injury at trial. Although the petitioner argued that a defendant who retaliated against an employee for filing a workers’ compensation claim should not benefit from the exclusivity provision of the WCA, the Appellate Division noted that the Legislature did not include this type of scenario in the statue nor did any of the case law recognize this type of claim as a remedy. As such, the Appellate Division reversed the December 2025 order granting the the plaintiff’s Section 40 summary judgment motion as well as the February 2026 reconsideration motion order. The Appellate Division noted that they did not intend to limit the plaintiff in his pursuit of his other claims on under the LAD, FMLA, and workers’ compensation retaliation causes of action.
