Dialysis provider DaVita Inc. announced that the United States Attorney's Office (USAO) for St. Louis has completed its investigation and is not taking any action against the company.

In March 2005, the St. Louis USAO initiated its inquiry with a subpoena and subsequent document requests in connection with a joint civil and criminal investigation. The requests covered a range of topics including financial relationships with physicians and joint ventures. They also covered other services provided to patients, including the administration and billing of the dialysis patient anemia drug Epogen.

DaVita said it cooperated with the government investigation and provided hundreds of thousands of documents. The USAO closed its investigation without filing any charges, without demanding any payments, and without seeking any changes in company policies, DaVita said.
