Medicare Paid New England Providers Twice for Nonphysician Outpatient Services Provided Shortly Before or During Inpatient Stays During Calendar Years 2013 and CY 2014 

Medicare payments to New England providers were not always correct for nonphysician outpatient services provided within 3 days prior to the date of admission, on the date of admission, or during Inpatient Prospective Payment System stays. For 75 of the 129 services we sampled, Medicare paid providers twice, resulting in total overpayments of $288,000. Based on our sample results, we estimated that the Medicare contractor made approximately $1.3 million in overpayments to hospital outpatient providers during calendar years 2013 and 2014.
