    24. Wellmark, Inc. 2006 24 Transfers Acute care patient is admitted to one hospital and subsequently transferred and admitted to another acute care hospital Transferring hospital will be paid the lesser of the per diem times the number of days or the APR-DRG payment Receiving hospital will be paid the APR-DRG payment Transfer per diems have been established for Level 1 & 2 and Level 3 & 4 for each APR-DRG

    25. Wellmark, Inc. 2006 25 Short Stays Acute care cases assigned to an APR-DRG severity level = 15 and the Patient Status Code is a 20, 40, 41 or 42, patient expired Relative weights were adjusted to be monotonic Case will be paid the lesser of the per diem times the number of days or the APR-DRG payment

    26.
