Cutan folicl center lymphoma, nodes of axilla and upper limb

This code signifies a diagnosis of cutaneous follicle center lymphoma that has metastasized to or originated in the lymph nodes located in the axilla and/or upper limb. This is a specific subtype of non-Hodgkin lymphoma primarily affecting the skin, but in this case, involving regional lymph nodes.

Apply this code when documentation explicitly states cutaneous follicle center lymphoma with involvement of axillary or upper limb lymph nodes. This is appropriate for both initial diagnoses and subsequent encounters where this specific site of involvement is confirmed. Pathological reports confirming the lymphoma subtype and imaging or biopsy confirming lymph node involvement are essential.

• Ensure documentation clearly distinguishes between primary cutaneous involvement and secondary lymph node involvement.
• Do not confuse with other types of cutaneous lymphomas or other non-Hodgkin lymphomas affecting these lymph nodes.
• Always sequence this code after the primary malignancy if the lymph node involvement is metastatic.
