ICD-10: D72.82

ICD-10 code D72.82 refers to a specific diagnosis of elevated white blood cell count, also known as leukocytosis. This condition is characterized by an increase in the number of white blood cells (WBCs) in the bloodstream, which can be indicative of various underlying health issues.

Clinical Description of Elevated White Blood Cell Count (D72.82)

Definition and Significance

Elevated white blood cell count is defined as a WBC count that exceeds the normal range, which is typically between 4,000 and 11,000 cells per microliter of blood. A count above this threshold can signal the body’s response to various stimuli, including infections, inflammation, stress, or more serious conditions such as leukemia or other hematological disorders[1][2].

Causes of Elevated WBC Count

The increase in white blood cells can be attributed to several factors, including:

• Infections: Bacterial, viral, or fungal infections can trigger an immune response, leading to leukocytosis.
• Inflammation: Conditions such as rheumatoid arthritis or inflammatory bowel disease can cause elevated WBC counts.
• Stress Responses: Physical or emotional stress can temporarily increase WBC levels.
• Allergic Reactions: Allergies can also lead to an increase in certain types of white blood cells, particularly eosinophils.
• Bone Marrow Disorders: Diseases such as leukemia or myeloproliferative disorders can result in significantly elevated WBC counts.
• Medications: Certain medications, including corticosteroids, can cause an increase in white blood cell production.

Symptoms and Diagnosis

Patients with elevated WBC counts may not exhibit specific symptoms directly related to the leukocytosis itself. However, symptoms may arise from the underlying condition causing the elevated count. Common symptoms associated with infections or inflammatory conditions include:

• Fever
• Fatigue
• Weakness
• Pain or discomfort in specific areas

Diagnosis typically involves a complete blood count (CBC) test, which measures the number of white blood cells and can help identify the type of WBCs that are elevated. Further diagnostic tests may be necessary to determine the underlying cause of the leukocytosis, including blood cultures, imaging studies, or bone marrow biopsies[3][4].

Treatment and Management

Management of elevated white blood cell count focuses on treating the underlying cause rather than the leukocytosis itself. Treatment options may include:

• Antibiotics for bacterial infections.
• Anti-inflammatory medications for inflammatory conditions.
• Chemotherapy or targeted therapy for hematological malignancies.
• Supportive care for stress-related leukocytosis.

Regular monitoring of blood counts may be necessary to assess the effectiveness of treatment and to ensure that the WBC count returns to normal levels[5].
