Neutropenic splenomegaly

This code signifies an enlarged spleen (splenomegaly) occurring in a patient with neutropenia, which is an abnormally low count of neutrophils, a type of white blood cell. It indicates a specific hematologic condition where the spleen's enlargement is associated with or caused by the neutropenic state.

Use this code when documentation clearly states both splenomegaly and neutropenia are present and clinically linked. This diagnosis is appropriate when the physician explicitly identifies the splenomegaly as being related to the patient's neutropenic condition. Supporting documentation would include CBC results showing neutropenia and imaging or physical exam findings confirming splenomegaly.

• Ensure documentation explicitly links the splenomegaly to the neutropenia; do not assume a relationship if not stated.
• Do not use this code for isolated splenomegaly (R16.1) or isolated neutropenia (D70.x) without the combined diagnosis.
• Consider sequencing this code after the underlying cause of neutropenia, if known and documented, such as a specific type of anemia or bone marrow disorder.
