Nodular lymphocy predom Hodgkin lymphoma, intrathorac nodes

This code identifies a specific subtype of Hodgkin lymphoma, characterized by a nodular growth pattern and a predominance of lymphocytes, affecting lymph nodes located within the chest cavity. This is a less common and generally more indolent form of Hodgkin lymphoma compared to classical types.

Assign this code when documentation clearly specifies a diagnosis of nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) and explicitly states involvement of intrathoracic lymph nodes (e.g., mediastinal, hilar, or tracheobronchial lymph nodes). Pathological confirmation of NLPHL is essential for accurate coding.

• Ensure the pathology report confirms "nodular lymphocyte predominant" subtype, not classical Hodgkin lymphoma.
• Verify the anatomical site of involvement is specifically "intrathoracic lymph nodes" to differentiate from other nodal or extranodal sites.
• Do not confuse with codes for classical Hodgkin lymphoma subtypes, which are classified separately.
