Stephen Hasegawa, a partner at Phillips & Cohen, represents whistleblowers in qui tam cases and whistleblower submissions involving numerous industries, such as healthcare, defense, aerospace, financial services and government procurement.
He was named to Lawdragon’s “500 Leading Lawyers in America” list for 2019 based on his work representing whistleblowers.
Mr. Hasegawa has played a key role in a number of whistleblower cases that have gotten significant results, including:
- A whistleblower case against a subsidiary of Community Health Systems and three CHS hospitals, which recovered $75 million for the federal government. The qui tam lawsuit alleged the hospitals engaged in a scheme to improperly increase federal payments intended for indigent patient care.
- A qui tam case against Office Depot that the company paid $68.5 million to settle. More than 1,000 California cities, counties, school districts and other government entities that allegedly were overcharged for office supplies shared in the recovery.
- A whistleblower lawsuit alleging the sale of substandard water distribution parts. That case resulted in more than $60 million recovered and three important appellate decisions, all in favor of Phillips & Cohen’s clients.
- A whistleblower case brought by a doctor against Freedom Health, Optimum Healthcare and their affiliates that settled for $32.5 million. It was the largest settlement so far of a false claims case against a Medicare Advantage plan.
- A qui tam case against U.S. Renal Care that alleged a company it acquired overcharged Medicare for an anemia drug used to treat dialysis patients. The case recovered $7.3 million for the government.
Mr. Hasegawa is co-counsel in a case against UnitedHealth Group and other defendants alleging use of fraudulent risk-adjustment data in Medicare Advantage plans. It is one of the first significant whistleblower cases alleging risk adjustment fraud by a Medicare Advantage plan run by a major health insurer.
Based partially on the results that Mr. Hasegawa obtained in two of his whistleblower cases, Phillips & Cohen was named to the National Law Journal’s “Elite Trial Attorneys” list in the employment law practice area.
Mr. Hasegawa joined Phillips & Cohen after eight years with Irell & Manella LLP in Los Angeles. He litigated numerous securities matters, including matters involving private securities litigation, SEC actions and inquiries, criminal investigations, internal investigation and state securities laws. Mr. Hasegawa’s practice also covered a diverse range of commercial disputes, including litigation under the California False Claims Act, entertainment-industry litigation, class actions and numerous cases concerning copyright, trademark, trade secrets and contracts.
Mr. Hasegawa graduated with honors from the University of Chicago Law School, where he was Articles Editor of the University of Chicago Legal Forum. He was named a “Super Lawyers Rising Star” in both Northern and Southern California.
Mr. Hasegawa serves as Phillips & Cohen LLP’s General Counsel. He is admitted to the bar in California.
