ICD-10-CM Code(s):        D61.3 Idiopathic aplastic anemia

Rationale:   The codes for anemia in ICD-10-CM are located in code blocks D50-D53 for nutritional anemias, D55-D59 for hemolytic anemia, and D60-D64 for aplastic and other anemias and other bone marrow failure syndromes. Aplastic anemia is located in code block D60-D64 with the codes broken down by type. Idiopathic means that the cause is unknown or arises suddenly. Pancytopenia is an abnormal reduction in the number of red blood cells, white blood cells, and blood platelets in the blood. It is a common sign/symptom/manifestation of aplastic anemia, so it would not be reported separately.
