Other codes that can never be billed with D64.0
These codes carry an Excludes1 note pointing at D64.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D64.0 alone.

Risk adjustment
D64.0 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 109 Acquired Hemolytic, Aplastic, and Sideroblastic Anemias1.144 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
