D72.828 ICD-10-CM Code: Other elevated white blood cell count

D72.828 is the ICD-10-CM diagnosis code for other elevated white blood cell count. This code describes an abnormally high number of white blood cells in the blood that doesn't fit into other specific categories of elevated white blood cell counts. It's used when a patient has more white blood cells than normal but the specific type or cause isn't classified elsewhere. D72.828 sits in the ICD-10-CM chapter for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (d50-d89), within the section covering other disorders of blood and blood-forming organs (d70-d77).

D72.828 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

Use this code only after ruling out more specific white blood cell elevation codes (like leukocytosis due to infection, medication, or specific cell types).
