ICD-10 Code D72.824 – Basophilia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D72.824 – Basophilia
What it is
Basophilia means an increased number of basophils in the blood. Use this code when the record documents basophilia as a finding, not a specific underlying disease.
Clinical signs
Clinical features vary; refer to documentation. It is usually identified on a complete blood count with differential and may appear with other abnormal white blood cell findings.
When to use this code
Use D72.824 when the provider documents basophilia as the diagnosis or a notable lab finding. It may be appropriate during evaluation of an abnormal blood count, especially when the chart does not identify a more specific cause.
If the record links basophilia to another confirmed condition, code the underlying condition as directed by documentation and coding rules. Check documentation when the cause is unclear or when the finding is incidental.
Do not use for
Do not use this code for eosinophilia, neutrophilia, or other white blood cell abnormalities. Do not assign it when basophils are normal or when the chart only says “abnormal CBC” without basophilia.
Coding tip
Confirm that basophilia is explicitly documented; if the abnormality is only implied by lab results, check documentation before coding.
