ICD-10 Code D61 – Other aplastic anemias and other bone marrow failure syndromes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D61 – Other aplastic anemias and other bone marrow failure syndromes
What it is
D61 identifies aplastic anemia and related bone marrow failure disorders not described by a more specific code. Use it when the marrow does not make enough blood cells and the documentation supports a broader bone marrow failure diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include anemia, infection risk, and bleeding tendency from reduced blood cell production, but the exact pattern depends on the specific marrow failure syndrome.
When to use this code
Use D61 when the provider documents aplastic anemia or another bone marrow failure syndrome without a more specific subtype. It also fits cases where the record confirms marrow failure but does not name a distinct inherited or acquired cause. Check documentation if the chart suggests a different hematologic disorder.
Do not use for
Do not use D61 for anemia with a known non-marrow cause, such as blood loss or nutritional deficiency. Also avoid it when the documentation supports a more specific diagnosis, such as a defined congenital marrow failure syndrome.
Coding tip
Code the most specific marrow failure diagnosis documented; if the record only says “aplastic anemia” or “bone marrow failure,” D61 is appropriate.
