About the D70–D77 Code Range
These conditions affect blood cells, the spleen, or blood-forming organs. They also include blood disorders associated with diseases classified elsewhere.
D70 is neutropenia, meaning fewer neutrophils in the blood. Its subdivisions distinguish congenital, drug-related, infection-related, cyclic, and other forms. D71 addresses how neutrophils function, while D72 groups other white blood cell disorders.
D73 separates spleen diseases by the condition named, such as a cyst or enlargement. D74 is methemoglobinemia, in which methemoglobin in the blood cannot carry oxygen normally. Its subdivisions distinguish congenital, other, and unspecified forms.
D75 groups other specified and unspecified blood disorders, including G6PD deficiency without anemia. D76 groups specified disorders involving blood-related tissues, including an infection-associated syndrome. D77 addresses blood and blood-forming organ disorders in diseases classified elsewhere.
FY 2027 changes: The FY 2027 ICD-10-CM update, effective October 1, 2026, deleted D71.
