About coding Dyshematopoietic congenital anemia
The ICD-10-CM code for Dyshematopoietic congenital anemia is D64.4 (Congenital dyserythropoietic anemia).
Within D64 (other anemias), D64.4 is specifically for congenital dyserythropoietic anemia. Related codes cover hereditary sideroblastic anemia (D64.0), secondary sideroblastic anemia due to disease (D64.1), secondary sideroblastic anemia due to drugs and toxins (D64.2), other sideroblastic anemias (D64.3), other specified anemias (D64.8) and anemia, unspecified (D64.9).
Don't report D64.4 together with the conditions in its Excludes1 note: Blackfan-Diamond syndrome (D61.01) and Di Guglielmo's disease (C94.0).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
