What CMS assigns to B02
All 16 codes group to MMTA - Infectious Disease, Neoplasms, and Blood-Forming Diseases (13) and Neuro Rehabilitation (3). 5 of the 16 count toward the C-diff, MRSA, E-coli, Sepsis comorbidity subgroup; 11 are assigned none. Every code can lead a claim.
- C-diff, MRSA, E-coli, Sepsis: counts toward the high comorbidity tier only in an interaction pair.
