Foliclar lymphoma, unsp, nodes of ing region and lower limb

This code signifies a diagnosis of follicular lymphoma, a type of non-Hodgkin lymphoma, when the specific subtype is not documented. The disease is localized to the lymph nodes within the inguinal region (groin) and/or the lower limbs. This indicates a primary or metastatic involvement of these specific lymphatic sites.

Use this code when documentation confirms follicular lymphoma affecting the lymph nodes of the inguinal region or lower limb, and the specific grade or subtype of follicular lymphoma is not specified. This code is appropriate when pathology reports confirm follicular lymphoma but lack further detail regarding its classification.

• Ensure documentation explicitly states "follicular lymphoma" and involvement of inguinal or lower limb lymph nodes.
• Avoid using this code if a more specific subtype (e.g., grade I, II, III, diffuse) of follicular lymphoma is documented; instead, use the more specific C82 subcategory.
• Always review the pathology report for the most precise diagnosis and anatomical site.
