ICD-10 Code D72.89 – Other specified disorders of white blood cells (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D72.89 – Other specified disorders of white blood cells
What it is
D72.89 is used for white blood cell disorders that do not fit a more specific ICD-10 category. It captures a documented abnormality of leukocytes when the record names another specified disorder.
Clinical signs
Clinical features vary; refer to documentation. You may see abnormal white blood cell findings, atypical cell descriptions, or a specified leukocyte disorder noted by the clinician without a better-defined code.
When to use this code
Use this code when the provider documents a specific white blood cell disorder that is not indexed elsewhere in ICD-10-CM. It is appropriate when the record clearly identifies the condition but does not support a more precise code. Check documentation if the term is vague.
Do not use for
Do not use D72.89 for nonspecific leukocytosis, leukopenia, or anemia-related findings unless the documentation supports a specified white blood cell disorder. Do not code it when another, more specific diagnosis is documented.
Coding tip
Match the provider’s exact wording to the index and confirm that no more specific leukocyte code applies before assigning D72.89.
