Edward H. Arens

Mr. Arens has represented clients under the qui tam, SEC, and IRS whistleblower programs including one whistleblower case that returned over $108.75 million lost to fraud in connection with the Iraq War and another that recovered $95.5 million lost to fraud related to California’s Medicaid expansion.

Edward “Ned” Arens, a partner at Phillips & Cohen, has extensive experience in representing whistleblowers, focusing on “qui tam” whistleblower cases and claims filed with the Securities and Exchange Commission and the Internal Revenue Service.

Recognized as one of Lawdragon’s “500 Leading Plaintiff Financial Lawyers” and one of the “Best Lawyers in America®,” Arens has returned hundreds of millions of dollars to the U.S. Treasury.

Mr. Arens has represented whistleblowers in a number of significant victories under the False Claims Act and SEC whistleblower program, spanning a wide range of industries.  Recent successes include a whistleblower case against KBR for allegedly defrauding the United States Army in connection with a contract to supply troops in Iraq and Afghanistan. The case returned $108.75 million to the U.S. government in 2023.  Mr. Arens also successfully represented a whistleblower in a managed care case related to California’s Medicaid expansion that resulted in settlements totaling $95.5 million.  Mr. Arens also recently secured significant victories in cases against Lincare Holdings, which paid $29 million for overcharging the Medicare Advantage program for oxygen equipment, and NextGen Healthcare, a large EHR software vendor, which paid $31 million to settle claims of fraud under the Meaningful Use program.

Mr. Arens’ other successes include a whistleblower case against Prime Healthcare, its CEO, and a cardiologist over alleged Anti-Kickback Statute (AKS) and Stark Law violations. The case is likely the largest settlement ($37.5 million) by a hospital in a case involving alleged kickbacks paid to a single physician.  Mr. Arens also settled ($32.5 million) a qui tam case against two Medicare Part C plans, Freedom Health and Optimum Healthcare, over alleged risk adjustment fraud.

Under the SEC and CFTC whistleblower programs, Mr. Arens has secured awards for whistleblowers on several multi-million-dollar SEC recoveries, including one case that resulted in a pathbreaking SEC enforcement action under the Dodd-Frank Act.

Other victories include a whistleblower case against Office Depot for allegedly overcharging more than 1,000 cities, counties, school districts, and other government entities for office supplies that settled for $68.5 million and a lawsuit against Alliant Techsystems for selling the U.S. Air Force defective flares that settled for $37 million.

Mr. Arens’ areas of expertise include fraud against Medicare and Medicaid managed care programs, including Medicare Advantage and Medicare Part D.  For over a decade, Mr. Arens has handled complex cases involving risk adjustment fraud, medical loss ratio (MLR) fraud, and fraud in securing Medicare Advantage and Medicare Part D contracts.  He is responsible for several pathbreaking recoveries in the area, including the first successful case against a healthcare supplier for overcharging Medicare Advantage plans for its services.

Mr. Arens has similarly deep experience with other types of healthcare fraud cases, including AKS violations by hospitals and pharmaceutical companies, violations of the Medicaid Drug Rebate Program, and fraud involving the government’s certification and subsidization of EHR technology.

Mr. Arens’ experience under the False Claims Act also includes numerous cases involving procurement fraud, including cases against defense contractors for overcharging the U.S. military for supplies, as well as evasion of customs duties.

Under the securities and commodities laws, Mr. Arens has represented whistleblowers in a wide range of matters, including claims relating to accounting fraud, disclosure failures, misleading financial products, Foreign Corrupt Practices Act violations, and violations of U.S. sanctions laws.

Mr. Arens also has extensive experience with IRS whistleblower claims, including claims involving complex tax shelters used by the financial industry and wealthy taxpayers.  He is co-author of Tax Whistleblower Laws and Programswhich is part of Bloomberg BNA’s Tax Management Portfolios. The portfolios are considered the gold standard in the legal world for those dealing with tax matters.  He won an important victory in US Tax Court for an IRS whistleblower client that will benefit other IRS whistleblowers who challenge IRS award determinations.

Mr. Arens graduated magna cum laude from the University of California, Hastings College of the Law, where he was a senior production editor of the Hastings Law Journal. While in law school, he was a legal intern with the U.S. Department of Health and Human Services, Office of the General Counsel, and with the U.S. Department of Justice, Antitrust Division.

Mr. Arens is admitted to the bar in California.
