Per CMS Transmittal 1981, the new Inpatient Psych PPS rates for discharges of 7/1/10 through 6/30/01 will be computed as follows:

• The Federal per diem base rate is $665.71. (This gets adjusted by DRG group , age and for which day in the inpatient stay)
• The fixed dollar loss threshold amount (for outliers) is $6,372.00.
• The labor-related share is 75.400 percent (i.e. 75.4% of the per diem rate is adjusted by the hospital’s wage index)
• The ECT rate is $286.60 (add-on for ECT shock treatment)

As before, the Medicare Cost Report of the hospital will impact the outlier calculation.
