Dialysis services provider DaVita announced that the U.S. attorney's office in Colorado has opened a grand jury investigation that appears to overlap at least partly with previously announced investigations by U.S. attorney's offices in St. Louis and Beaumont, Texas, and HHS' inspector general's office in Dallas.
DaVita announces federal probe in Colorado
Denver-based DaVita said it understands the Colorado investigation is very preliminary and it will cooperate.
The related Texas investigation concerns a February 2007 request for information from the inspector general for records relating to claims for erythropoietin, or EPO, submitted to Medicare, according to a DaVita filing. In August 2007, DaVita also received a subpoena from the inspector general seeking similar documents. The requested documents relate to services provided from 2001 to 2004 by a number of DaVita centers.
The Missouri investigation began with a subpoena to DaVita in March 2005 and required production of a wide range of documents relating to operations, including documents related to pharmaceutical and other services provided to patients, relationships with pharmaceutical companies, and financial relationships with physicians and joint ventures, according to DaVita.
