CMS has released the FY 2011 SSI data for IPPS hospitals, LTCHs, and IRFs.  This data will be used to determine the disproportionate share adjustment for hospitals and the low-income payment adjustment for IRFs for cost reporting periods beginning in FY 2011.  The change in SSI ratios for IPPS hospitals ranged from -0.30373 to 0.36215 (with one provider receiving a much larger increase of 0.94778).  According to our calculations, the average change across all providers from FY 2010 to FY 2011 is -0.00038.

The FY 2011 SSI Ratios are available from the CMS website by clicking here.  The Medicare Learning Network Matters article discussing the SSI Ratios can be accessed here.
