Mycosis fungoides, nodes of inguinal region and lower limb

This code signifies a diagnosis of mycosis fungoides, a type of cutaneous T-cell lymphoma, specifically when it has metastasized or primarily involves the lymph nodes located in the inguinal region and the lower extremities. It indicates nodal involvement of this specific non-Hodgkin lymphoma.

Use this code when pathology reports confirm mycosis fungoides affecting the lymph nodes of the groin or leg. Documentation should clearly state the diagnosis of mycosis fungoides and specify involvement of these particular lymph node sites, often confirmed by biopsy.

• Ensure the documentation differentiates between primary cutaneous involvement and nodal involvement.
• Do not confuse with other types of cutaneous lymphomas or other non-Hodgkin lymphomas affecting these nodes.
• Sequence this code after the primary diagnosis of mycosis fungoides if the nodal involvement is a secondary manifestation.
