What CMS assigns to E64
None of the 6 codes is assigned a clinical group. 1 of the 6 counts toward the Other Combined Immunodeficiencies and Malnutrition, includes graft-versus-host-disease comorbidity subgroup; 5 are assigned none. None can lead a claim. CMS attaches a code-first note to all 6.
- Other Combined Immunodeficiencies and Malnutrition, includes graft-versus-host-disease: can award the low comorbidity tier as a secondary diagnosis.
