Motion to Exclude Expert Witness
Motions to exclude an expert witness are tactics by an opposing party to prevent the admissibility of testimony in court or to a jury. In other words, these motions may focus on alleged deficiencies in an Expert’s qualifications, Expert methodology, Expert’s basis for opinions, and other factors. Accordingly, if an Expert survives a motion to exclude his or her testimony, it is favorable for their reputation. Consequently, if the motion to exclude is DENIED, this is a favorable outcome for the expert, and usually for the side that retained the expert.
A motion in limine, Hallmark, or Frye motion or Daubert Challenge may be introduced to exclude an expert witness. Importantly, a Chief U.S. District Judge, a U.S. District Judge, one State Judge, and an arbitrator denied motions to exclude Michael Arrigo. Another Arbitrator consented to a stipulation of Arrigo’s expert qualifications.
To elaborate, here are the cases and the summary of Rulings by Federal Judges, State Judges and Arbitrators involving Michael Arrigo as an expert witness:
Medicare Fraud Case (Federal), Local Coverage Determinations (LCDs), National Coverage Determinations (NCDs), Medically Necessary Care, Damages
- DENIED – UNITED STATES of AMERICA v. Clifford Shoemake et al. CRIMINAL CASE NO. 16-00002. Order from the bench. Chief District Judge Frances Marie Tydingco-Gatewood of the U.S. District Court of Guam April 2018.Denied motion to exclude. Arrigo is retained by Defendant in alleged $30 million Medicare fraud case. When Defendant’s opposition prevailed, the Prosecution withdrew Daubert challenge.

To elaborate, Senior District Judge Ronald S.W. Lew of the U.S. District Court, Central District of California noted “…Mr. Arrigo is a damages expert…,” “…Mr. Arrigo clearly has the relevant qualifications necessary …” and noted Arrigo’s expertise in medical coding, billing, electronic health records and as a Medicare fraud damages. “…Accordingly, the Court finds that Mr. Arrigo has sufficient specialized knowledge to provide an opinion…” Feb. 2018. The motion to exclude the expert witness was denied.

Personal Injury Case (State of California), Usual Customary and Reasonable Cost of Medical Care, Affordable Care Act Out of Pocket Maximum, Essential Health Benefits
- DENIED (2) – Allure Nichols v. Eskaton, Inc., et al., CASE NO.: CVPO-2017-916 Order after hearing on Parties’ in Limine Motions. California Superior Court Judge Peter M. Williams. March 28, 2019. Retained by Plaintiff, in a personal injury case. To explain, Defendants argue the medical care was paid by a capitated Medicare Part C plan, and regardless of the services provided, there was, in effect no payment made for Plaintiff’s hospital care. The Court ruled that the reasonable value of the medical services is at issue – not the amount incurred—must be used instead. “This value is generally determined by expert testimony.” The motion to exclude the expert witness was denied.
(1) To elaborate, the Motion was granted in part, denied in part, based on procedural grounds, not the expertise or methods of the Expert (in that Judge Lew’s ruling permitted Arrigo to give testimony and found that his specialized knowledge and methodology were sound, but precluded Arrigo from stating how many hours a physician might have spent performing specific procedures). “Relator fails to allege in the Amended Complaint that Dr. Khossoussi was unable to work the time he billed to Medicare. Further, Dr. Khossoussi argues that Mr. Arrigo’s opinions regarding the possibility of Dr. Khossoussi working the time he billed are unfounded and irrelevant to Relator’s remaining claims. Because Relator has failed to offer any opposition to these arguments, any opposition is waived.”
(2) Denied, subject to voir dire. However, after Arrigo’s testimony at his deposition that an Economist retained by the Defendant had put forth a flawed methodology and unreliable conclusions, the Defendant did not call the opposing expert as a witness at trial. Therefore Arrigo was not called as a witness since he had been disclosed only as a rebuttal expert only. Therefore, there was no voir dire.
