List of ICD-9 codes 280–289: diseases of the blood and blood-forming organs

The List of ICD-9 codes 280–289 includes a range of diseases related to the blood and blood-forming organs. These codes are used to classify and categorize various conditions and disorders that affect the blood cells, bone marrow, and other components of the circulatory system. Here are some examples of the diseases covered in this category:

• 1. Anemias (280–285): These codes encompass different types of anemia, including iron deficiency anemia, megaloblastic anemia, hemolytic anemia, and aplastic anemia. Anemia is characterized by a decrease in the number of red blood cells or a decrease in the amount of hemoglobin in the blood.
• 2. Coagulation defects (286–287): These codes are used to identify disorders of blood clotting, such as hemophilia, von Willebrand disease, and other clotting factor deficiencies. These conditions can lead to excessive bleeding or abnormal clotting.
• 3. Purpura and other hemorrhagic conditions (287–288): This category includes codes for disorders characterized by bleeding or bruising, such as idiopathic thrombocytopenic purpura (ITP), thrombotic thrombocytopenic purpura (TTP), and other platelet disorders.
• 4. Diseases of white blood cells (288–289): These codes cover various conditions affecting white blood cells, including leukemias, lymphomas, and other disorders of the lymphatic system. Leukemia is a cancer of the blood-forming tissues, while lymphomas are cancers that originate in the lymphatic system.

It is important to note that the ICD-9 codes have been replaced by the ICD-10 codes, which provide a more detailed and comprehensive classification system. The ICD-10 codes offer greater specificity and accuracy in documenting and diagnosing diseases of the blood and blood-forming organs.
