Medicare Compliance Review of Mayo Clinic Florida for 2013 and 2014 

Mayo Clinic Florida (the Hospital) complied with Medicare billing requirements for 185 of the 199 inpatient and outpatient claims that we reviewed. However, the Hospital did not fully comply with Medicare billing requirements for the remaining 14 claims, resulting in net overpayments totaling $71,000. These errors occurred primarily because the Hospital did not have adequate controls to prevent the incorrect billing of Medicare claims within the selected risk areas that contained errors. On the basis of our sample results, we estimated that the Hospital received overpayments of at least $103,000 for the audit period.
