About D64

D64 is the ICD-10-CM diagnosis code for other anemias. It belongs to block D60-D64 (aplastic and other anemias and other bone marrow failure syndromes) and chapter 3 (diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D64.0 (anemia), D64.1 (disease), D64.2 (toxins), D64.3 (anemias), D64.4 (anemia), D64.8 (anemias) and D64.9 (unspecified).

Don't report D64 together with the conditions in its Excludes1 note: refractory anemia (D46.-) and refractory anemia with excess blasts in transformation [RAEB T] (C92.0-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
