ICD-10 Code D61.09 – Other constitutional aplastic anemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D61.09 – Other constitutional aplastic anemia
What it is
D61.09 identifies a constitutional, inherited form of aplastic anemia that is not classified elsewhere. It describes bone marrow failure causing reduced blood cell production.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include anemia, easy bruising or bleeding, recurrent infections, and other signs of low blood counts.
When to use this code
Use D61.09 when the record documents other constitutional aplastic anemia or a congenital marrow-failure disorder with aplastic anemia. It is appropriate when the provider specifies an inherited cause rather than an acquired aplastic anemia. Check documentation if the chart only says “aplastic anemia” without a constitutional or hereditary qualifier.
Do not use for
Do not use this code for acquired aplastic anemia, drug-induced marrow suppression, or anemia from blood loss. If the documentation does not clearly support a constitutional form, check documentation.
Coding tip
Confirm the provider’s wording for hereditary or constitutional disease before assigning D61.09.
