Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

DaVita Inc. (the “Company”) has been advised that it will be receiving a request for documents, which could include an administrative subpoena from the Office of Inspector General for the U.S. Department of Health and Human Services. The request is in connection with an inquiry by the United States Attorney’s office for the Eastern District of New York regarding payment for infusion drugs covered by the New York Medicaid composite payment system for dialysis. We believe this inquiry is civil in nature. We do not know the time period covered by the inquiry.

We understand that certain other providers that operate dialysis clinics in New York and provide services to New York Medicaid patients also may be receiving or have received a similar request for documents. We intend to cooperate with the government to provide responsive documents. To the Company’s knowledge, no proceedings have been initiated against it at this time, although the Company cannot predict whether proceedings might be initiated. Any negative findings could result in substantial financial penalties against the Company, exclusion from future participation in the Medicare and Medicaid programs, and criminal penalties.

(d) Exhibits.

Neither this Form 8-K nor the attached Exhibit are to be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, nor shall this Form 8-K nor the attached Exhibit be deemed incorporated by reference in any filing under the Securities Act of 1933 (except as shall be expressly set forth by specific reference in such filing).
