Continuing, here is another excerpt from the ruling by U.S. District Judge Lew regarding Michael F Arrigo as an expert witness:
“…Mr. Arrigo clearly has the relevant qualifications necessary to provide an opinion regarding the potential damages from submission of allegedly false claims. Mr. Arrigo has experience in both state and federal court providing expert opinions that involved medical billing, coding, Medicare, and Medi–Cal. See Arrigo Report, Ex. F. Mr. Arrigo also has training in medical coding and billing reimbursement, and he has spoken on the topic of electronic health records. See Grover Mot. to Exclude Opp’n Decl., Ex. 2. Accordingly, the Court finds that Mr. Arrigo has sufficient specialized knowledge to provide an opinion on the potential Medicare damages. See United States v. Abonce– Barrera, 257 F.3d 959, 964 (9th Cir. 2001)(“[I]n considering the admissibility of testimony based on some ‘other specialized knowledge,’ Rule 702 generally is construed liberally.” (internal quotations omitted)).”
“…Accordingly, the Court finds that Mr. Arrigo’s opinions regarding the potential damages attributable to the alleged kickback scheme and Triggiani’s provision of services in violation of her Medicare exclusion are admissible.”
