Other decreased white blood cell count

This code signifies a reduction in the total number of white blood cells (leukocytes) in the peripheral blood, excluding specific conditions like neutropenia, lymphocytopenia, or eosinopenia. It indicates a general decrease in white blood cell count that doesn't fit more specific classifications.

Use this code when documentation indicates a low white blood cell count without specifying which particular type of leukocyte is decreased, or when multiple types are decreased but not meeting criteria for a more specific cytopenia. This code is appropriate when the provider explicitly diagnoses "decreased white blood cell count, not otherwise specified" or similar generalized terms.

• Do not use this code if a more specific type of leukopenia (e.g., neutropenia, lymphocytopenia) is documented; use the appropriate specific code instead.
• Always review the complete blood count (CBC) results and physician's interpretation to ensure the decrease is not attributable to a more specific condition.
• Consider sequencing this code after the underlying cause of the decreased white blood cell count, if known and documented.
