The US Attorney’s Office alleges that many of Mercy Health’s sleep tests were inaccurately scored, did not qualify for Medicare reimbursement, and resulted in medically unnecessary claims for machines used to treat sleep apnea.

The case began as a federal complaint filed under the False Claims Act. It alleged Mercy Health inaccurately reported test results and created reports from sleep tests with diagnoses made by non-certified sleep technologists.

Kenneth Parker, U.S. Attorney for the Southern District of Ohio, announced the settlement Friday.
