Other non-follicular lymphoma, intrathoracic lymph nodes

This code signifies a malignant lymphoma that originates from lymphoid tissue, excluding follicular lymphoma, and is specifically located within the intrathoracic lymph nodes. This includes various subtypes of non-follicular lymphomas affecting lymph nodes in the chest cavity, such as mediastinal or hilar lymph nodes.

Apply this code when documentation confirms a diagnosis of a non-follicular lymphoma with primary involvement of lymph nodes within the thorax. This typically follows a biopsy and pathological confirmation of the lymphoma subtype and its intrathoracic location.

• Ensure the pathology report explicitly states "non-follicular" and specifies intrathoracic lymph node involvement.
• Do not use this code if the lymphoma is identified as follicular; a different C82.x code would be appropriate.
• Sequence this code as the primary diagnosis when the lymphoma is the reason for the encounter, followed by codes for any associated symptoms or complications.
