FOOTNOTES:	* This variable was used in the calculation of the LTCH PPS payments under the site neutral payment rate (412.522) and under the short-stay outlier payment adjustment ( 412.529(d)(4)).
	**MS-LTC-DRG relative weights are multiplied by an adjustment factor calculated as the total estimated LTCH PPS payment amount divided by the estimated MS-LTC-DRG inlier payment amount. Cases that are projected to be paid the estimated MS-LTC-DRG inlier payment amount are adjusted by a factor equal to 1.  Cases that are high cost outliers are adjusted by a factor greater than 1.  Cases that are short-stay outliers are adjusted by a factor less than 1. The case-mix-index is then calculated as the average of these adjusted MS-LTC-DRG relative weights.
