Nodular scler Hodgkin lymph, nodes of head, face, and neck

This code identifies a specific subtype of Hodgkin lymphoma, nodular sclerosis, affecting the lymph nodes located in the head, face, and neck regions. This is a malignant neoplasm characterized by the presence of Reed-Sternberg cells within a fibrotic background.

Apply this code when documentation confirms a diagnosis of nodular sclerosis Hodgkin lymphoma with primary involvement or metastasis specifically to the lymph nodes of the head, face, or neck. This diagnosis is typically established through biopsy and histopathological examination.

• Ensure the pathology report explicitly states "nodular sclerosis" and specifies involvement of head, face, or neck lymph nodes.
• Do not use this code for other subtypes of Hodgkin lymphoma or for involvement of lymph nodes outside the specified anatomical regions.
• Sequence this code as the primary diagnosis when the patient is receiving treatment for this specific lymphoma.
