DaVita HealthCare Partners said Tuesday it will pay $389 million to settle criminal and civil anti-kickback investigations and plans to end joint ventures with kidney doctors involving 28 dialysis clinics. Denver-based DaVita's CEO, Kent Thiry, announced in an earnings call with shareholders that the company has "agreed to a framework" for settling federal investigations into some of the company's relationships with kidney doctors' offices. He said the exact settlement still is being finalized, but that both he and federal attorneys expect to hammer out the details in coming months.
