Mixed cellular Hdgkn lymph, nodes of ing rgn and lower limb

This diagnosis code signifies a specific subtype of Hodgkin lymphoma, mixed cellularity, affecting the lymph nodes located in the groin area and extending into the lower extremities. Mixed cellularity Hodgkin lymphoma is characterized by a heterogeneous cellular infiltrate including Reed-Sternberg cells, lymphocytes, eosinophils, and plasma cells.

Apply this code when documentation confirms a pathological diagnosis of mixed cellularity Hodgkin lymphoma. The medical record must explicitly state involvement of lymph nodes within the inguinal region or any part of the lower limb. This code is appropriate for both initial diagnosis and subsequent encounters related to this specific site involvement.

• Ensure the pathology report specifically identifies "mixed cellularity" as the subtype of Hodgkin lymphoma.
• Verify that the documentation clearly indicates involvement of inguinal or lower limb lymph nodes, not other sites.
• Do not confuse with other Hodgkin lymphoma subtypes or non-Hodgkin lymphomas.
