Review of Acute Care Inpatient Same-Day Readmissions at St. Mary's Hospital

St. Mary's Hospital did not always bill same-day readmissions in accordance with Federal requirements. For 17 of the 53 same-day readmissions in our review, St. Mary's Hospital incorrectly billed the second admission as a separate inpatient stay instead of a continuous stay based on the first admission, resulting in $89,000 in overpayments. These overpayments occurred because St. Mary's Hospital did not have adequate training to review same-day readmissions and prevent incorrect billings.
