Mixed cellularity Hodgkin lymphoma, lymph nodes mult site

This code identifies a specific subtype of Hodgkin lymphoma, characterized by a heterogeneous cellular infiltrate including lymphocytes, eosinophils, histiocytes, and Reed-Sternberg cells. It indicates that this mixed cellularity type of Hodgkin lymphoma is present in multiple lymph node regions throughout the body.

Use this code when diagnostic pathology reports confirm mixed cellularity Hodgkin lymphoma and imaging or clinical examination indicates involvement of lymph nodes in more than one anatomical region. Documentation should clearly specify the subtype of Hodgkin lymphoma and the widespread nature of lymph node involvement.

• Ensure the pathology report explicitly states "mixed cellularity" and not another Hodgkin lymphoma subtype.
• Confirm that multiple lymph node sites are documented as affected, not just a single region.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any associated symptoms or complications.
