FOOTNOTES:	* This variable was used in the calculation of the LTCH PPS adjusted payment amount for a short-stay outlier (SSO) case for an amount payable under subpart O based on an amount comparable to the hospital inpatient prospective payment system per diem amount under the SSO policy as discussed at § 412.529(c)(2)(iv).
	"**The most recent available cost report data were used (FYs 2006 - 2007). A ""zero"" value may indicate unavailable or incomplete data. "
	"*** Equivalent cases are determined based on the total estimated LTCH PPS payment amount divided by the estimated MS-LTC-DRG inlier payment amount.  Cases that are projected to receive the estimated MS-LTC-DRG inlier payment amount are counted as 1 full case.  Cases that are high cost outliers are counted as more than a full case (for example, 1.2 cases)  Cases that are low cost/short-stay outliers are counted as less than a full case (for example, 0.8 cases).  In determining equivalent cases for this impact analysis, cases with covered days of 7 days or fewer were removed."
