Quest Diagnostics set a record in April 2009 when it paid $302 million to the government to settle a Medicare fraud case alleging the company sold faulty medical testing kits. It was the largest qui tam (whistleblower) settlement paid by a medical lab for manufacturing and distributing a faulty product. In May 2011, Quest paid $241 million to the state of California to settle a False Claims Act case that alleged the company had overcharged Medi-Cal, the state’s Medicaid program, and provided illegal kickbacks as incentives for healthcare providers to use Quest labs.
