What CMS assigns to B96
None of the 16 codes is assigned a clinical group. 2 of the 16 count toward the C-diff, MRSA, E-coli, Sepsis comorbidity subgroup; 14 are assigned none. None can lead a claim.
- C-diff, MRSA, E-coli, Sepsis: counts toward the high comorbidity tier only in an interaction pair.
