HIPPS Code Calculation Change

A change was made in version 5186 to the OASIS HIPPS calculation to allow the 1st secondary diagnosis code (M1022 b.)  to be scored as primary if the preceding diagnosis code (M1020 a.)  is a non-case mix ‘V’ code and the 1st secondary diagnosis code (M1022 b.) group is [4] Diabetes, [19] Skin 1, or [10] Neuro 1.  This change relates to another change requiring that only certain fracture (Fx) ICD9 codes entered into M1024 will score points and they must match with specific ‘V’ codes in the preceding M0120 or M0122 fields.   This refers to the Federal Register Vol. 77, No. 217, page 61117 and the matching ‘V’ code and related Fx codes are found in Table 25 in the same section of the register .  These changes became effective January 1, 2013.  It is our understanding that this change was done to minimize the use of M0124 and is also a move towards ICD10 which will probably eliminate the M1024 fields.
