What CMS assigns to B16
All 4 codes group to MMTA - Infectious Disease, Neoplasms, and Blood-Forming Diseases. 2 of the 4 count toward the C-diff, MRSA, E-coli, Sepsis comorbidity subgroup; 2 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.
