About D63

D63 is the ICD-10-CM diagnosis code for anemia in chronic diseases classified elsewhere. 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 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D63.0 (disease), D63.1 (disease) and D63.8 (elsewhere).

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