ICD-10 Code D72.8 – Other specified disorders of white blood cells (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D72.8 – Other specified disorders of white blood cells
What it is
D72.8 is used for white blood cell disorders that do not fit a more specific ICD-10 category. It captures documented abnormalities of leukocytes when the chart names a specific disorder outside the standard code set.
Clinical signs
Clinical features vary; refer to documentation. You may see abnormal white blood cell findings, unexplained leukocyte-related disorder descriptions, or a clinician’s diagnosis of a specified white blood cell condition not otherwise classified.
When to use this code
Use D72.8 when the provider documents a named disorder of white blood cells and no more specific code applies. It is appropriate for clearly specified leukocyte conditions that are not covered by another D72 code. If the record is vague, check documentation before assigning this code.
Do not use for
Do not use D72.8 for nonspecific abnormal blood test results without a diagnosed disorder. Also avoid it when a more specific leukocyte code, such as one for a defined white blood cell count abnormality or other classified disorder, is documented.
Coding tip
Code the exact provider wording and confirm whether a more specific D72 diagnosis is available before defaulting to D72.8.
