Other elevated white blood cell count

This code signifies an elevated white blood cell count (leukocytosis) that is not otherwise specified as neutropenia, eosinophilia, or lymphocytosis. It indicates an increase in the total number of leukocytes in the peripheral blood, without specifying which particular type of white blood cell is predominantly elevated. This finding often suggests an underlying inflammatory, infectious, or stress response.

Use this code when documentation indicates an elevated WBC count, but the specific type of leukocytosis (e.g., neutrophilic, eosinophilic, lymphocytic) is not identified or is not the primary focus. This code is appropriate when the physician notes "elevated WBC" or "leukocytosis" without further differentiation. Supporting documentation would include laboratory results showing a high total WBC count without a detailed differential or when the differential is not explicitly abnormal for a specific cell line.

• Do not use this code if a more specific type of leukocytosis (e.g., D72.820 for lymphocytosis, D72.821 for eosinophilia) is documented.
• Always sequence this code after the definitive diagnosis or condition causing the elevated WBC, if known.
• Ensure the medical record clearly states an elevated WBC count; avoid coding based solely on abnormal lab values without physician interpretation.
