What CMS assigns to D63
None of the 3 codes is assigned a clinical group. All 3 count toward the Hemolytic, Aplastic, and Other Anemias comorbidity subgroup. None can lead a claim. CMS attaches a code-first note to all 3.
- Hemolytic, Aplastic, and Other Anemias: can award the low comorbidity tier as a secondary diagnosis.
