Non-follic lymph, unsp, nodes of ing region and lower limb

This code signifies a diagnosis of lymphoma that is not of follicular origin and is broadly distributed (diffuse), with its primary manifestation located in the lymph nodes of the groin area and the lower extremities. It indicates a type of non-Hodgkin lymphoma where the specific subtype is not further identified.

Use this code when documentation confirms a diagnosis of diffuse non-follicular lymphoma affecting the inguinal and/or lower limb lymph nodes, and the pathologist has not specified a more precise subtype (e.g., diffuse large B-cell lymphoma). This code is appropriate when the medical record explicitly states "unspecified non-follicular lymphoma" or "diffuse lymphoma, unspecified type" with involvement of these specific anatomical sites.

• Always seek more specific documentation regarding the lymphoma subtype (e.g., B-cell, T-cell, or specific histological type) before resorting to an "unspecified" code.
• Ensure the documentation clearly identifies the involvement of inguinal region and/or lower limb lymph nodes; otherwise, a more general site code may be appropriate.
• This code should not be used if the lymphoma is explicitly stated as follicular or if the primary site is elsewhere.
