Aplastic anemia, unspecified

This code represents a severe form of bone marrow failure where the body stops producing enough new blood cells (red, white, and platelets) without a known cause. It signifies a pancytopenia resulting from hypoplastic or aplastic bone marrow.

Assign this code when documentation indicates a diagnosis of aplastic anemia without further specification of its type (e.g., congenital, secondary, or other specified aplastic anemias). This code is appropriate when the etiology of the aplastic anemia is not documented or is unknown.

• Avoid using this code if a more specific type of aplastic anemia is documented (e.g., D61.0- for constitutional, D61.1 for drug-induced).
• Ensure the documentation clearly states "aplastic anemia" and lacks further specificity regarding its cause or type.
• Do not confuse with other types of anemia that do not involve bone marrow failure, such as iron deficiency anemia (D50.-) or vitamin B12 deficiency anemia (D51.-).
