Nodular scler Hodgkin lymph, nodes of axilla and upper limb

This diagnosis code identifies a specific subtype of Hodgkin lymphoma, characterized by the presence of nodular sclerosis, and specifically located in the lymph nodes of the axilla and/or upper limb. It indicates a malignant neoplasm originating from lymphocytes, with distinct histological features.

Apply this code when documentation confirms a diagnosis of nodular sclerosis Hodgkin lymphoma affecting the lymph nodes of the armpit or upper extremity. Supporting documentation includes pathology reports detailing the nodular sclerosis subtype and imaging or physical exam findings specifying involvement of axillary or upper limb lymph nodes.

• Ensure the pathology report explicitly states "nodular sclerosis" and not another Hodgkin lymphoma subtype.
• Verify the anatomical site of involvement is limited to the axilla and/or upper limb; do not use if other sites are documented.
• Code additional sites of involvement with the appropriate C81.1- subcategory if multiple regions are affected.
