ICD-10 Code D61.9 – Aplastic anemia, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D61.9 – Aplastic anemia, unspecified
What it is
D61.9 identifies aplastic anemia when the specific cause or type is not documented. It is used for a bone marrow failure condition that leads to reduced production of blood cells.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include fatigue, pallor, easy bruising, bleeding, or infections related to low blood cell production.
When to use this code
Use D61.9 when the record states aplastic anemia but does not specify an underlying cause, severity, or subtype. It also fits when the provider documents bone marrow failure consistent with aplastic anemia and no more specific code is supported. Verify that the diagnosis is confirmed in the chart.
Do not use for
Do not use this code for other anemias, such as iron deficiency or hemolytic anemia. If the documentation identifies a specific aplastic anemia type or cause, check documentation for a more precise code.
Coding tip
Code D61.9 only when the provider documents aplastic anemia without further detail.
