D75Other and unspecified diseases of blood and blood-forming organs

D75 is the ICD-10-CM diagnosis code for other and unspecified diseases of blood and blood-forming organs. It belongs to block D70-D77 (other disorders of blood and blood-forming organs) 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D75.0 (erythrocytosis), D75.1 (polycythemia), D75.8 (organs), D75.9 (unspecified) and D75.A (anemia).

The conditions in its Excludes2 note aren't part of D75, but may be coded alongside it if the patient has both: acute lymphadenitis (L04.-), chronic lymphadenitis (I88.1), enlarged lymph nodes (R59.-), hypergammaglobulinemia NOS (D89.2) and 2 more.

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