ICD-10 Code D55.3 – Anemia due to disorders of nucleotide metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D55.3 – Anemia due to disorders of nucleotide metabolism
What it is
This code identifies anemia caused by an inherited or acquired disorder that affects nucleotide metabolism. Use it when documentation links the anemia to that specific metabolic problem.
Clinical signs
Patients may show general anemia findings such as fatigue, pallor, weakness, or reduced exercise tolerance. Clinical features vary; refer to documentation.
When to use this code
Use D55.3 when the provider documents anemia due to a disorder of nucleotide metabolism, or when the condition is clearly stated as the cause of the anemia. It may apply in genetic or metabolic disorders where the anemia is part of the recorded diagnosis.
If the record only says “anemia” without a cause, do not assume this code. Check documentation for the specific metabolic disorder and its relationship to the anemia.
Do not use for
Do not use this code for anemia due to iron deficiency, vitamin deficiency, blood loss, hemolysis, or chronic disease. Check documentation if the cause is not explicitly linked to nucleotide metabolism.
Coding tip
Code the underlying disorder and the anemia only when the provider documents the causal relationship clearly.
