Secondary sideroblastic anemia due to disease

This code represents a type of anemia characterized by the presence of ring sideroblasts in the bone marrow, which are red blood cell precursors with iron granules accumulated around the nucleus. This specific form of sideroblastic anemia is not inherited but rather develops as a consequence of another underlying medical condition.

Use this code when documentation clearly indicates sideroblastic anemia that is secondary to another disease process, such as myelodysplastic syndromes, chronic infections, inflammatory conditions, or certain malignancies. The physician's diagnosis must explicitly state "secondary sideroblastic anemia" or link the sideroblastic anemia to a specific underlying disease.

• Ensure the documentation specifies the underlying disease causing the secondary sideroblastic anemia; code the underlying disease first if it is the primary reason for the encounter.
• Distinguish this from primary (idiopathic) sideroblastic anemia (D64.0) or other specified sideroblastic anemias.
• Do not use this code for sideroblastic anemia due to drugs or toxins (D64.2) or other causes (D64.3).
