Cutan folicl cntr lymph, nodes of ing region and lower limb

This diagnosis code signifies a specific type of non-Hodgkin lymphoma, cutaneous follicle center lymphoma, when it affects the lymph nodes located in the groin area (inguinal region) or anywhere in the lower limbs. This is a primary lymphoma of the skin that has metastasized or presented in these regional lymph nodes.

Use this code when documentation clearly indicates a diagnosis of cutaneous follicle center lymphoma with confirmed involvement of lymph nodes in the inguinal region or any part of the lower extremity. This typically follows a biopsy and pathological confirmation of the lymphoma type and its spread to these specific nodal sites.

• Ensure the pathology report explicitly identifies the lymphoma as "cutaneous follicle center lymphoma" and confirms involvement of inguinal or lower limb lymph nodes.
• Do not use this code for primary cutaneous follicle center lymphoma confined to the skin without nodal involvement; a different code for primary cutaneous lymphoma would be appropriate.
• Verify laterality (left, right, bilateral) if specified in the documentation, as some codes offer laterality options, though this specific code does not.
