  CASE MIX INDEX SETS FOR USE WITH VERSION 5.12 of M3PI


The following 4 Case Mix Index (CMI) Sets are appropriate for use
with version 5.12 of M3PI.  The 4 sets are designated by CMI Set
Control Codes (A01, A02, B01, and B02).

CMI Set Codes starting with an "A" are Medicare PPS sets, and these 
sets are based on nursing time, rehabilitation time, and ancillary
costs.  CMI Set Codes starting with a "B" are Medicaid or Research 
Sets, and these sets are based on nursing time only.

  SET CODE:  A01
  SET NAME:  Medicare PPS Rural--07/01/98  
  SET DATE:  03/29/1998

  Description:  Set A01 is appropriate for RUG-III classification
                of Medicare residents in Rural facilities.  This 
                set is a provisional set for use with the Medicare
                Prospective Payment System (PPS) to be implemented
                nationally on 07/01/1998.  

                Set A01 is based on provisional Medicare PPS payment 
                rates that include nursing time, rehabilitation time,
                and selected ancillary costs.  This set is based on
                calculations for a large representative sample of 
                Medicare residents.

                Set A01 gives the ordinal position of each group 
                rather than the actual numeric index.  At this 
                time, the underlying numeric indices are still 
                under review and subject to change before PPS 
                implementation on 07/01/1998.  A future set will
                provide the actual numeric indices when available.

                CAUTION:  Set A01 is a provisional Medicare PPS
                set and the ordinal positions of the groups and
                the resulting Medicare PPS RUG-III classifications
                may change before actual PPS implementation.

                large multistate research studies conducted in 1995
                and 1997.  This set is based on a Medicare-oriented
                sample of residents in selected Skilled Nursing 
                Facilities in several states in 1995 and 1997.
