Nodular lymphocyte predom Hodgkin lymphoma, intra-abd nodes

This code identifies a specific subtype of Hodgkin lymphoma, characterized by a nodular growth pattern and a predominance of lymphocytes, affecting lymph nodes located within the abdominal cavity. This is a distinct and less aggressive form of Hodgkin lymphoma compared to classical types.

Apply this code when documentation explicitly states a diagnosis of nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) and specifies involvement of intra-abdominal lymph nodes. This diagnosis is typically confirmed by biopsy and histopathological examination.

• Ensure the pathology report specifically identifies "nodular lymphocyte predominant" and not other Hodgkin lymphoma subtypes.
• Verify that the affected lymph nodes are clearly documented as "intra-abdominal" to differentiate from other anatomical sites.
• Do not use this code for classical Hodgkin lymphoma affecting intra-abdominal nodes; a different C81 subcategory would be appropriate.
