About D59

D59 is the ICD-10-CM diagnosis code for acquired hemolytic anemia. It belongs to block D55-D59 (hemolytic anemias) 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 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D59.0 (anemia), D59.1 (anemias), D59.2 (anemia), D59.3 (syndrome), D59.4 (anemias), D59.5 ([Marchiafava-Micheli]), D59.6 (causes), D59.8 (anemias) and 1 more.

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