Medicare Compliance Review of University of Washington Medical Center

University of Washington Medical Center (the Medical Center), located in Seattle, Washington, complied with Medicare billing requirements for 94 of the 157 inpatient claims we reviewed. However, the Medical Center did not fully comply with Medicare billing requirements for the remaining 63 claims, resulting in net overpayments of approximately $2.2 million for calendar years (CYs) 2010 through 2012 (60 claims) and CY 2013 (3 claims). These overpayments occurred primarily because the Medical Center did not have adequate controls to prevent the incorrect billing of Medicare claims within the selected risk areas that contained errors.
