Plus: One RAC reveals information about how it will evaluate claims during its review process. The physician-owned practice will pay $2 million to resolve allegations that it submitted false claims to Medicare, the OIG announced in a March 25 press release. The settlement -- one of the largest ever negotiated under the OIG's Civil Monetary Penalties authority -- will resolve the following allegations against the practice: • Improperly providing diagnostic tests to Medicare beneficiaries without the required treating physicians' orders • Billing for certain tests under CPT codes not supported by the medical records • Failing to satisfy "certain other Medicare billing and coverage requirements," the OIG noted in its press release. "OIG will investigate and pursue enforcement actions against health practitioners who engage in a pattern of billing Medicare for services that were not ordered by the patients' treating physicians," said Inspector General Daniel Levinson in a statement.
