Behn noted that whistleblowers, known as " qui tam relators ," can receive between 15 and 30 percent of the governments' recovery. Behn has represented whistleblowers in several successful multi-state qui tam actions, which obtained large recoveries for Medicaid fraud. Behn garnered national attention for representing a pharmacist-whistleblower in the $179 million multi-state Medicaid fraud settlement with Johnson & Johnson for alleged fraud involving kickbacks paid to nursing homes (D. Mass. 07 CV 10288-RGS). The nursing homes' pharmacy, Omnicare, also paid $99 million for its alleged role (D.Mass., No. 07-10026-RGS). Behn and his client also recovered over $120 million in multi-state Medicaid fraud settlements of drug switching allegations against Walgreens, CVS, and Omnicare.
