What CMS assigns to E83
30 of the 31 codes group to MMTA - Other; 1 is assigned no clinical group. 15 of the 31 count toward the Obesity, and Disorders of Metabolism and Fluid Balance comorbidity subgroup; 16 are assigned none. 30 of the 31 can lead a claim.
- Obesity, and Disorders of Metabolism and Fluid Balance: counts toward the high comorbidity tier only in an interaction pair.
