Nodular sclerosis Hodgkin lymphoma, lymph nodes mult site

This code identifies a specific subtype of Hodgkin lymphoma, nodular sclerosis, affecting lymph nodes in more than one anatomical region. Nodular sclerosis is the most common histological subtype of Hodgkin lymphoma, characterized by collagen bands that divide the lymphoid tissue into nodules.

Use this code when the pathology report confirms nodular sclerosis Hodgkin lymphoma and imaging or clinical examination indicates involvement of lymph nodes in multiple, non-contiguous sites (e.g., cervical and inguinal lymph nodes). Documentation must clearly specify the nodular sclerosis subtype and multifocal lymph node involvement.

• Ensure the pathology report explicitly states "nodular sclerosis" as the subtype.
• Verify that the medical record documents involvement of lymph nodes in at least two distinct anatomical regions.
• Do not use this code for single-site lymph node involvement; refer to site-specific codes for nodular sclerosis Hodgkin lymphoma.
