Oth types of foliclar lymph, nodes of ing rgn and lower limb

This code signifies a diagnosis of follicular lymphoma, a type of non-Hodgkin lymphoma, specifically when the primary or most significant involvement is observed in the lymph nodes located in the inguinal region (groin) and/or the lower limbs. It covers follicular lymphoma subtypes not classified as grade I, II, III, or diffuse.

Apply this code when documentation confirms a diagnosis of follicular lymphoma, specified as "other types" (e.g., not otherwise specified grade, or a rare variant not fitting other categories), with documented involvement of lymph nodes in the inguinal region or lower extremities. This code requires clear pathological confirmation of follicular lymphoma and anatomical site specificity.

• Ensure the pathology report explicitly states "follicular lymphoma, other types" or a similar non-specific grade, and clearly identifies inguinal or lower limb lymph node involvement.
• Do not use this code if a specific grade (e.g., Grade I, II, III) of follicular lymphoma is documented; instead, select the appropriate grade-specific code.
• Sequence this code as the primary diagnosis when it represents the reason for the encounter or the most significant condition being treated.
