There are eight different ICD-9 codes for anemia, according to the Centers for Medicare & Medicaid Services. They range from 285.0, the code for sideroblastic anemia, to 285.9, the code for anemia unspecified.
The Centers for Disease Control and Prevention defines the International Classification of Diseases as a system used to assign specific codes to medical procedures and diagnoses. ICD-9 refers to the ninth revision of the system. The World Health Organization says that ICD-9 codes are used to store and retrieve medical information. These codes are also used to prepare morbidity and mortality statistics.
There are ICD-9 codes for sideroblastic anemia, acute posthemorrhagic anemia, anemia in neoplastic disease, anemia of other chronic disease, anemia unspecified, other specified anemias, anemia in chronic kidney disease and antineoplastic chemotherapy-induced anemia, according to CMS.
