On April 10, 2012, the Department of Justice (“DOJ”) announced that Tenet Healthcare Corporation agreed to pay $42.75 million to settle a False Claim Act lawsuit involving Medicare overbilling claims.  See Press Release, Dep’t of Justice, Dallas-based Tenet Healthcare Pays More Than $42 Million to Settle Allegations of Improperly Billing Medicare (Apr. 10, 2012), http://www.justice.gov/opa/pr/2012/April/12-civ-446.html.  Tenet runs several inpatient rehabilitation facilities (IRFs) that are able to receive higher reimbursement rates from Medicare because they typically provide more intensive rehabilitation services that other facilities such as nursing homes.  The DOJ alleged that between May 15, 2005, and December 31, 2007, Tenet overbilled Medicare for the treatment of patients who did not in fact qualify for admission to their IRFs.  The settlement is notable because it resulted from Tenet’s decision to voluntarily self-disclose the IRF violations under the terms of a 5-Year Corporate Integrity Agreement that Tenet previously entered into with the OIG in September 2006 (unrelated to this settlement).
