Anaplstc lg cell lymph, ALK-pos, nodes of ing rgn & low lmb

This code represents a specific type of non-Hodgkin lymphoma characterized by large, anaplastic cells and the presence of the anaplastic lymphoma kinase (ALK) protein. The disease primarily affects the lymph nodes located in the inguinal region and the lower limbs. It is an aggressive form of lymphoma requiring specific diagnostic and treatment approaches.

This code is appropriate for patients diagnosed with ALK-positive anaplastic large cell lymphoma where the primary site of involvement is documented as the lymph nodes of the inguinal region and/or lower limb. Documentation should clearly specify the ALK-positive status and the anatomical location of the affected lymph nodes.

• Ensure documentation explicitly states "ALK-positive" to differentiate from ALK-negative anaplastic large cell lymphoma.
• Verify the specific anatomical location of lymph node involvement; this code is specific to inguinal region and lower limb.
• Do not use this code if the lymphoma is ALK-negative or if the primary site of involvement is outside the specified anatomical regions.
