Other Hodgkin lymphoma, intra-abdominal lymph nodes

This diagnosis code signifies a type of Hodgkin lymphoma that does not fit into the classic or nodular lymphocyte-predominant categories, specifically affecting the lymph nodes located within the abdominal cavity. This includes involvement of mesenteric, retroperitoneal, and other intra-abdominal lymph node groups.

Apply this code when the pathology report confirms a diagnosis of Hodgkin lymphoma that is not otherwise specified (e.g., "other Hodgkin lymphoma") and imaging or surgical findings clearly indicate primary or metastatic involvement of intra-abdominal lymph nodes. Documentation should specify the type of Hodgkin lymphoma as "other" and the anatomical location as intra-abdominal.

• Ensure the pathology report explicitly states "other Hodgkin lymphoma" to differentiate from classic or nodular lymphocyte-predominant types.
• Verify that documentation clearly identifies intra-abdominal lymph node involvement, such as mesenteric, retroperitoneal, or periaortic nodes.
• Do not use if the Hodgkin lymphoma type is specified as classic or nodular lymphocyte-predominant, even if intra-abdominal nodes are involved; use the appropriate subcategory for those types.
