On March 7, 2013, CMS published a notice announcing changes to certain Medicare payment adjustments under the Medicare hospital inpatient prospective payment systems (IPPS) for fiscal year (FY) 2013, in accordance with the American Taxpayer Relief Act of 2012 (ATRA). Specifically, the ATRA extends changes to the payment adjustment for low-volume hospitals and extends the Medicare-dependent hospital (MDH) program for an additional year, through FY 2013, which is projected to increase FY 2013 payments to IPPS hospitals by $509 million.
