Oth types of non-Hodgkin lymphoma, intrathoracic lymph nodes

This code signifies a diagnosis of non-Hodgkin lymphoma that doesn't fit into more specific categories, with its primary manifestation or involvement located within the intrathoracic lymph nodes. This includes lymphomas with unusual histologies or those that are not otherwise classifiable but are confirmed to be non-Hodgkin type and affecting lymph nodes within the chest cavity.

Use this code when documentation clearly specifies a diagnosis of "other specified non-Hodgkin lymphoma" and explicitly states involvement of intrathoracic lymph nodes (e.g., mediastinal, hilar, or tracheobronchial lymph nodes). This code is appropriate when a more precise sub-type of non-Hodgkin lymphoma (e.g., diffuse large B-cell, follicular) cannot be assigned, but the intrathoracic location is confirmed.

• Ensure the pathology report confirms a non-Hodgkin lymphoma diagnosis and specifies "other specified" or a similar non-specific classification.
• Verify that imaging or biopsy reports definitively identify intrathoracic lymph node involvement.
• Do not use this code if a more specific type of non-Hodgkin lymphoma (e.g., C83.32 for diffuse large B-cell lymphoma of intrathoracic lymph nodes) is documented.
