ICD-10 Code D72.82 – Elevated white blood cell count (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D72.82 – Elevated white blood cell count
What it is
This code identifies an elevated white blood cell count, also called leukocytosis. Use it when the record documents increased white blood cells without a more specific underlying diagnosis.
Clinical signs
Clinical features vary; refer to documentation. It is usually identified on a complete blood count and may be noted during evaluation for infection, inflammation, stress, or other causes.
When to use this code
Use this code when the clinician documents elevated white blood cell count as a finding and does not name a more specific condition. It may also support coding when the abnormal count is being monitored or evaluated. If the cause is known and documented, code the cause instead when appropriate.
Do not use for
Do not use this code for a confirmed infection, hematologic disorder, or other documented cause of the abnormal count when a more specific diagnosis applies. Check documentation if the record is unclear.
Coding tip
Assign the abnormal lab code only when the elevated count is clinically relevant and specifically documented by the provider.
