Other Hodgkin lymphoma, lymph nodes of multiple sites

This code signifies a diagnosis of Hodgkin lymphoma that does not fit into the classic or nodular lymphocyte-predominant subtypes, and involves lymph nodes in multiple, non-contiguous anatomical regions. It represents a less common or unclassifiable form of Hodgkin lymphoma with widespread lymphatic involvement.

Apply this code when the pathology report confirms Hodgkin lymphoma, but the specific subtype is documented as "other" or unclassifiable, and imaging or physical examination indicates involvement of lymph nodes in more than one body region (e.g., cervical and inguinal). Documentation must clearly state the "other" subtype and multi-site lymph node involvement.

• Ensure the pathology report explicitly states "other Hodgkin lymphoma" or a similar unclassifiable subtype.
• Verify documentation of multiple, non-contiguous lymph node regions affected.
• Do not use for Hodgkin lymphoma localized to a single site or for specified subtypes like classic or nodular lymphocyte-predominant.
