ICD-10 Code D72.828 – Other elevated white blood cell count (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D72.828 – Other elevated white blood cell count
What it is
D72.828 identifies a documented increase in white blood cells that does not fit a more specific leukocytosis code. Use it when the record states an elevated white blood cell count and no clearer cause is provided.
Clinical signs
Clinical features vary; refer to documentation. The chart may note leukocytosis on laboratory testing, sometimes alongside signs of infection, inflammation, stress, or other underlying conditions.
When to use this code
Use this code when the provider documents other elevated white blood cell count and does not specify a more exact diagnosis. It may also fit when the abnormal count is recorded as a finding during evaluation and the underlying reason is not yet established. Check documentation if a more specific leukocyte disorder is named.
Do not use for
Do not use this code for a clearly documented specific leukocytosis type or a confirmed underlying condition that better explains the lab result. Do not assign it if the record only shows a normal count or a different hematologic disorder.
Coding tip
Code the documented abnormality, but always look for a more specific diagnosis before defaulting to D72.828.
