Leukocytosis ICD-10-CM Codes

A leukocytosis ICD code should be used when a documented increase in white blood cell count requires clinical attention, especially when the exact cause is unspecified. It is commonly applied in infection, inflammation, or other disorders involving the immune system or blood-forming organs.

Treatment for leukocytosis depends on the underlying cause and may include antibiotics for infections, anti-inflammatory drugs, or medications to address immune or blood disorders. In some cases, managing related conditions like spleen disorders or functional immune abnormalities is also necessary.

A diagnosis code for leukocytosis indicates an abnormally high white blood cell count in the patient’s blood or body fluid. It helps healthcare providers identify potential immune or hematologic disorders and ensures accurate documentation for treatment and billing.
