ICD-10 Code D61.03 – Fanconi anemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D61.03 – Fanconi anemia
What it is
D61.03 identifies Fanconi anemia, an inherited bone marrow failure disorder. It is used when documentation specifies this diagnosis, often linked to congenital anomalies and progressive blood cell production problems.
Clinical signs
Clinical features vary; refer to documentation. Common findings include pancytopenia, easy bruising, fatigue, recurrent infections, short stature, and congenital abnormalities such as thumb or renal defects.
When to use this code
Use D61.03 when the provider documents Fanconi anemia as the confirmed diagnosis. This code fits outpatient, inpatient, or problem-list documentation that clearly identifies the inherited aplastic anemia syndrome. If the record only says bone marrow failure or aplastic anemia without naming Fanconi anemia, check documentation.
Do not use for
Do not use this code for acquired aplastic anemia, unspecified anemia, or other inherited marrow failure syndromes unless Fanconi anemia is documented. Check documentation if the chart uses a family history only.
Coding tip
Code the condition only when Fanconi anemia is explicitly stated; otherwise, query for clarification.
