Nodular sclerosis Hodgkin lymphoma, intrathorac lymph nodes

This code identifies a specific subtype of Hodgkin lymphoma, nodular sclerosis, when the disease is located within the intrathoracic lymph nodes. Nodular sclerosis is the most common histological subtype of Hodgkin lymphoma, characterized by collagen bands forming nodules and lacunar cells.

Assign this code when diagnostic pathology reports confirm nodular sclerosis Hodgkin lymphoma and imaging or biopsy definitively localizes the disease to lymph nodes within the chest cavity (e.g., mediastinal, hilar). This code is appropriate for initial diagnosis and subsequent encounters where the intrathoracic involvement is still present.

• Ensure documentation explicitly states "nodular sclerosis" and "intrathoracic lymph nodes."
• Do not confuse with other Hodgkin lymphoma subtypes or extrathoracic involvement.
• Sequence as the primary diagnosis when this is the reason for the encounter, followed by any associated signs/symptoms or complications.
