Constitutional (pure) red blood cell aplasia

This code identifies a rare, inherited disorder characterized by a severe deficiency in red blood cell production, leading to anemia. It specifically refers to a congenital form of red blood cell aplasia, often presenting in infancy or early childhood.

Assign this code when documentation clearly indicates a diagnosis of constitutional or pure red blood cell aplasia, such as Diamond-Blackfan anemia. Supporting documentation should specify the congenital or inherited nature of the red blood cell aplasia, distinguishing it from acquired forms.

• Do not code with D60.9 (Acquired pure red cell aplasia) as per the Excludes1 note.
• Ensure documentation specifies "constitutional" or "pure" red blood cell aplasia to differentiate from other aplastic anemias.
• Consider additional codes for associated symptoms or genetic conditions if documented.
