Mantle cell lymphoma, intrathoracic lymph nodes

This code signifies a diagnosis of mantle cell lymphoma (MCL) specifically affecting lymph nodes located within the thoracic cavity. MCL is a rare, aggressive B-cell non-Hodgkin lymphoma characterized by the translocation t(11;14)(q13;q32). Intrathoracic involvement indicates the disease is present in mediastinal, hilar, or other lymph nodes within the chest.

Apply this code when documentation confirms a pathological diagnosis of mantle cell lymphoma with explicit mention of involvement of intrathoracic lymph nodes. This typically follows biopsy and histopathological examination of affected lymph nodes, often identified via imaging studies like CT or PET scans.

• Ensure the pathology report specifically identifies "mantle cell lymphoma" and "intrathoracic lymph nodes."
• Do not use this code if the lymphoma type is unspecified or if the intrathoracic involvement is not explicitly documented.
• Consider additional codes for any associated symptoms or complications, such as pleural effusion or airway obstruction, if documented.
