Stephen S. Hasegawa
Stephen Hasegawa 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 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.
