Other and unspecified diseases of blood and blood-forming organs (D75) ICD-10-CM
The D75 code range covers other and unspecified diseases of blood and blood-forming organs with 17 ICD-10-CM diagnosis codes. 13 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the D75 range.
Cytopenia
A deficiency in or reduction of the number of blood cells.
Familial Polycythemia
Polycythemia that occurs in groups of related individuals.
Heparin Induced Thrombocytopenia
A life-threatening complication of heparin therapy. It results in immune-mediated thrombocytopenia and, in 25-50 percent of the patients, thrombotic complications.
Polycythemia
An increase in the total red cell mass of the blood. (Dorland, 27th ed)
Primary Myelofibrosis
A de novo myeloproliferation arising from an abnormal stem cell. It is characterized by the replacement of bone marrow by fibrous tissue, a process that is mediated by CYTOKINES arising from the abnormal clone.
Thrombocytosis
Increased numbers of platelets in the peripheral blood. (Dorland, 27th ed)
About the D75 Code Range
These diseases affect blood or the organs that form it. The category includes named conditions and a disease left unspecified.
D75.0 and D75.1 distinguish familial and secondary red blood cell conditions. D75.8 groups other specified diseases. Within it, D75.82 separates heparin-related platelet conditions by immune involvement and whether a type is specified. D75.83 distinguishes other high platelet counts from unspecified high platelet counts.
D75.9 is for an unspecified disease of blood or blood-forming organs. D75.A identifies glucose-6-phosphate dehydrogenase deficiency without anemia.
