On April 30, 2010, CMS published a notice on that updates Medicare prospective payment system (PPS) payment rates for inpatient psychiatric hospital services provided by inpatient psychiatric facilities (IPFs) for discharges occurring during the rate year beginning July 1, 2010 through June 30, 2011. CMS estimates that the rule will increase Medicare payments by $91 million, resulting from a 2.4% market basket increase, partially offset by a 0.25% reduction mandated by the PPACA, and an update to the outlier fixed dollar loss threshold amount.
