Mantle cell lymphoma, nodes of ing region and lower limb

This code signifies a specific type of non-Hodgkin lymphoma, mantle cell lymphoma, affecting the lymph nodes located in the groin area and/or the lower extremities. Mantle cell lymphoma is an aggressive B-cell lymphoma characterized by the proliferation of small to medium-sized lymphocytes.

Apply this code when documentation explicitly states a diagnosis of mantle cell lymphoma with confirmed involvement of inguinal lymph nodes or lymph nodes within the lower limb. This diagnosis is typically established through biopsy and histopathological examination.

• Ensure the documentation clearly specifies "mantle cell lymphoma" and not another subtype of non-Hodgkin lymphoma.
• Verify that the anatomical site of involvement is precisely documented as inguinal lymph nodes or lymph nodes of the lower limb.
• Do not use this code if the lymphoma is localized to other regions; instead, select the appropriate site-specific code.
