ICD-10 Code D72 – Other disorders of white blood cells (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D72 – Other disorders of white blood cells
What it is
D72 identifies disorders of white blood cells that do not fit a more specific category. Use it for documented abnormalities affecting leukocytes when the record does not support a narrower code.
Clinical signs
Clinical features vary; refer to documentation. Records may note abnormal white blood cell findings, unexplained leukocyte changes, or a diagnosed white cell disorder without a more specific subtype.
When to use this code
Use D72 when the provider documents an unspecified or other disorder of white blood cells and no more detailed diagnosis is available. It may apply when the chart confirms a leukocyte disorder but does not identify the exact cell line or cause.
Code from the provider’s wording, not from isolated lab abnormalities alone. If the record supports a specific leukocyte condition, choose that code instead of D72.
Do not use for
Do not use D72 for routine abnormal blood counts without a diagnosed white blood cell disorder. Do not use it when documentation supports a more specific leukocyte condition.
Coding tip
Check the assessment and final diagnosis carefully; D72 is a fallback code, not a substitute for a more precise white blood cell diagnosis.
