The government has intervened in a lawsuit against IPC The Hospitalist Co., and its subsidiaries, alleging that IPC submitted false claims to federal health care programs, the Justice Department announced. The lawsuit alleges that IPC physicians sought payment for higher and more expensive levels of medical service than were actually performed – a practice commonly referred to as “upcoding.” Specifically, the lawsuit alleges that IPC encouraged its physicians to bill at the highest levels regardless of the level of service provided, trained physicians to use higher level codes and encouraged physicians with lower billing levels to “catch up” to their peers. The lawsuit was filed by Dr. Bijan Oughatiyan, a former IPC physician, under the qui tam, or whistleblower, provisions of the False Claims Act, which permit private parties to sue for false claims on behalf of the government and to share in any recovery. The Act also allows the government to intervene or take over the lawsuit, as it has done in this case, and to recover three times its damages plus civil penalties. The government has asked the U.S. District Court in Chicago for 120 days to file its own complaint stating its allegations.
