Non-billable headerICD-10-CM

D64 is a non-billable header ICD-10-CM code for other anemias. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

refractory anemia (D46.-)
refractory anemia with excess blasts in transformation [RAEB T] (C92.0-)

Other codes that can never be billed with D64

These codes carry an Excludes1 note pointing at D64. 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 alone.

E53.1Pyridoxine deficiency
E83.1Disorders of iron metabolism
R71Abnormality of red blood cells
D53.9Nutritional anemia, unspecified

Risk adjustment

D64 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
