Hodgkin lymphoma, unsp, nodes of ing region and lower limb

This code signifies a diagnosis of Hodgkin lymphoma where the specific subtype is not documented, and the disease is located in the lymph nodes of the inguinal region or the lower limb. It indicates a primary lymphatic malignancy affecting these particular anatomical sites.

Use this code when the medical record confirms Hodgkin lymphoma in the inguinal or lower limb lymph nodes, but the pathologist or clinician has not specified the exact histological subtype (e.g., nodular sclerosis, mixed cellularity). Documentation should clearly state "Hodgkin lymphoma" and specify involvement of inguinal or lower limb lymph nodes without further subtyping.

• Ensure the documentation explicitly states "unspecified" or lacks information regarding the specific Hodgkin lymphoma subtype.
• Verify that the affected lymph nodes are definitively in the inguinal region or lower limb; do not use for other anatomical sites.
• If a specific subtype of Hodgkin lymphoma is identified, a more precise code from the C81 series should be used.
