D75.8Other specified diseases of blood and blood-forming organs

D75.8 is the ICD-10-CM diagnosis code for other specified diseases of blood and blood-forming organs. It belongs to category D75 (other and unspecified diseases of blood and blood-forming organs), 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.

Within D75, choose D75.8 (Other specified diseases of blood and blood-forming organs) only when documentation doesn't support a more specific option: familial erythrocytosis (D75.0), secondary polycythemia (D75.1), disease of blood and blood-forming organs, unspecified (D75.9) and glucose-6-phosphate dehydrogenase (G6PD) deficiency without anemia (D75.A).

To report this condition, pick the subcode that matches the documentation: D75.81 (myelofibrosis), D75.82 ((HIT)), D75.83 (thrombocytosis), D75.84 (disorders) and D75.89 (organs).

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