DaVita's mounting government probes

DaVita recently disclosed a new investigation from federal attorneys in Florida, who are questioning whether the dialysis conglomerate submitted federal claims for blood, urine and fecal lab tests without ensuring the tests were accurate.

The big picture: This marks DaVita's sixth federal investigation. The other probes include alleged overbilling of Medicare Advantage patients and the company's relationships to a charity that helps dialysis patients sign up for generous-paying insurance. DaVita said it "is cooperating with the government."
