When the stay at the transferring hospital is a diagnosis-related-group (DRG) paid by the department, and does not qualify as a low outlier, the transferring hospital is paid a graduated per diem rate for each day of care allowed by the department. If the case qualifies as a low cost outlier, the hospital will be paid the graduated per diem amount or low cost outlier payment amount, whichever is lower. The per diem rate is determined by dividing that hospital's rate for the appropriate DRG by that DRG's average length of stay as determined by the department. Payment for the first day of service will be two times the per diem rate. For subsequent allowed days, the basic per diem rate will be paid up to the full DRG payment amount. Unless the case qualifies as a high outlier, payment to the transferring hospital will not exceed the appropriate DRG rate that would have been paid had the injured worker not been transferred to another hospital.
