Other constitutional aplastic anemia

This code signifies a rare bone marrow failure disorder characterized by pancytopenia resulting from hypoplastic or aplastic bone marrow. It encompasses various congenital or inherited forms of aplastic anemia that do not fit into more specific categories like Fanconi anemia. Patients typically present with symptoms related to anemia, thrombocytopenia, and neutropenia.

Use this code for documented cases of constitutional aplastic anemia where the specific type (e.g., Fanconi, Diamond-Blackfan) is not identified or is explicitly ruled out, but an inherited etiology is suspected or confirmed. Documentation should clearly state "constitutional aplastic anemia, other" or similar terminology, indicating a non-acquired form.

• Ensure documentation differentiates constitutional aplastic anemia from acquired forms (D61.9).
• Always review for more specific constitutional aplastic anemia codes (e.g., D61.01 for Fanconi anemia) before assigning this code.
• Code any associated manifestations or complications (e.g., infections, bleeding) separately.
