10 of the 12 codes group to MMTA - Other (9) and MMTA - Gastrointestinal tract and Genitourinary system (1); 2 are assigned no clinical group. 1 of the 12 counts toward the Other disorders of the kidney and ureter, excluding chronic kidney disease and ESRD comorbidity subgroup; 11 are assigned none. 10 of the 12 can lead a claim.
- Other disorders of the kidney and ureter, excluding chronic kidney disease and ESRD: counts toward the high comorbidity tier only in an interaction pair.
