Zimmer Holdings, one of several orthopedics companies under fire for making payments to doctors that raised conflict-of-interest issues, said it has banned company personnel from making gifts to doctors. The firm said it is also banning physician endorsements, suspending payments to some of its consultants, reviewing royalty payments, and taking steps to prevent sales and marketing employees from having contact with doctors that consult for the firm, reports Bloomberg News. The company will also conduct its charitable giving through independent third parties.

Zimmer was one of four orthopedics firms that paid a combined $311 million to the U.S. government to settle claims of antikickback violations. It is one of five that agreed to have its physician-payment practices undergo federal monitoring. In exchange, the Department of Justice will not pursue criminal charges.
