Anaplstc lg cell lymph, ALK-pos, nodes of axla and upr limb

This code signifies a specific type of non-Hodgkin lymphoma characterized by the presence of anaplastic large cells and a positive anaplastic lymphoma kinase (ALK) protein rearrangement. It specifically indicates that this aggressive cancer is located within the lymph nodes of the axilla and/or upper limb.

Use this code when documentation confirms a diagnosis of ALK-positive anaplastic large cell lymphoma affecting the lymph nodes of the armpit or upper extremity. Pathological reports confirming ALK positivity and the specific anatomical location are essential for accurate coding.

• Ensure the pathology report explicitly states "ALK-positive" for anaplastic large cell lymphoma.
• Verify the anatomical site is limited to the axillary or upper limb lymph nodes; other sites require different codes.
• Do not confuse with ALK-negative anaplastic large cell lymphoma (C84.7-) or other types of non-Hodgkin lymphoma.
