Lymphocyte-rich Hodgkin lymphoma, intra-abd lymph nodes

This code signifies a specific subtype of Hodgkin lymphoma, characterized by a predominance of lymphocytes, affecting lymph nodes located within the abdominal cavity. It represents a malignant neoplasm originating from lymphocytes, specifically the B-cell lineage, with a distinct histological pattern.

This code is appropriate when documentation confirms a diagnosis of lymphocyte-rich Hodgkin lymphoma, and imaging or pathological reports specify involvement of intra-abdominal lymph nodes. It should be used for initial diagnosis, active treatment, or follow-up of this specific malignancy.

• Ensure the pathology report explicitly states "lymphocyte-rich" subtype of Hodgkin lymphoma.
• Verify that the anatomical site of involvement is clearly documented as "intra-abdominal lymph nodes" to differentiate from other nodal sites.
• Do not confuse with other Hodgkin lymphoma subtypes or non-Hodgkin lymphomas; precise histological and anatomical documentation is crucial.
