What D64.9 covers
D64.9 is for anemia when the record does not give the type or cause. It is common in primary care, internal medicine and hospital settings.
Specific anemias have their own codes: iron deficiency anemia is D50.-, acute posthemorrhagic anemia D62, and anemia in chronic kidney disease or neoplastic disease D63.1 and D63.0. Siblings in D64 cover sideroblastic anemias (D64.0-D64.3), congenital dyserythropoietic anemia (D64.4) and other specified anemias (D64.8-).
Billing and coding notes
D64.9 is billable but unspecified. When the provider documents the type or the cause, the specific anemia code replaces it.
The D64 category has an excludes1 for refractory anemia (D46.-) and refractory anemia with excess blasts in transformation (C92.0-). Those are coded with the myelodysplastic and leukemia codes, never with D64.9.
