About the D70–D77 Code Range
ICD-10 codes D70 through D77 cover a wide variety of disorders affecting blood and blood-forming organs, including specific conditions related to white blood cell abnormalities, spleen diseases, methemoglobinemia, and rare hematologic syndromes.
This code range includes D70 for neutropenia, encompassing congenital forms such as Kostmann syndrome (D70.0), drug-induced and chemotherapy-related neutropenia, and cyclic neutropenia. It also covers white blood cell functional disorders (D71) like chronic granulomatous disease and genetic leukocyte anomalies (D72.0). Disorders of white blood cells including eosinophilia and related hypersensitivity syndromes are coded from D72.1 to D72.19, with detailed subtypes such as hypereosinophilic syndrome and drug rash with eosinophilia. Codes D73 address various spleen diseases like hyposplenism and hypersplenism, while D74 relates to methemoglobinemias, including congenital and acquired forms. Other specified and unspecified blood disorders fall under D75 and D76, including familial erythrocytosis (D75.0), thrombocytosis, heparin-induced thrombocytopenia, and hemophagocytic lymphohistiocytosis (D76.1). The range concludes with D77 for blood disorders linked to other diseases, such as secondary cytopenia. These codes aid precise classification of complex hematologic conditions for clinical documentation and coding accuracy.
