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 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 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.
- A qui tam case against Hawthorn Pharmaceuticals alleging Medicaid fraud that settled for $2.8 million.
- A whistleblower lawsuit that claimed a general contractor had fraudulently obtained government construction business that was intended for small businesses owned by disabled military veterans. The case settled for $1.1 million.
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.
