What CMS assigns to D56
All 8 codes group to MMTA - Infectious Disease, Neoplasms, and Blood-Forming Diseases. All 8 count toward the Hemolytic, Aplastic, and Other Anemias comorbidity subgroup. Every code can lead a claim.
- Hemolytic, Aplastic, and Other Anemias: can award the low comorbidity tier as a secondary diagnosis.
