Foliclar lymph grade III, unsp, nodes of ing rgn and low lmb

This diagnosis code signifies a specific type of non-Hodgkin lymphoma, follicular lymphoma, which is characterized by a grade III cellular differentiation. The "unspecified" aspect indicates that further subtyping of the grade III follicular lymphoma (e.g., with or without diffuse areas) is not documented. The disease is located in the lymph nodes of the inguinal region and/or the lower limb.

This code is appropriate for patients diagnosed with grade III follicular lymphoma where the primary or metastatic site is documented as the lymph nodes in the groin or leg. Documentation should clearly state the histological type as follicular lymphoma, the grade as III, and specify the affected anatomical region.

• Ensure documentation explicitly states "grade III" for follicular lymphoma; otherwise, a less specific code may be required.
• Verify the anatomical site is precisely documented as inguinal lymph nodes or lymph nodes of the lower limb.
• Do not use this code if the documentation specifies follicular lymphoma, grade III, with diffuse areas, as a more specific code exists.
