On January 27, 2011, CMS published a proposed rule that would update prospective payment rates for Medicare inpatient hospital services provided by inpatient psychiatric facilities (IPFs) for discharges occurring July 1, 2011 through September 30, 2012 and make other changes to the IPF PPS. The proposed rule also would rebase and revise the Rehabilitation, Psychiatric, and Long-Term Care (RPL) market basket, and make certain clarifications and corrections to terminology and regulations text. Comments will be accepted until March 22, 2011.
