Follicular lymphoma grade II, intra-abdominal lymph nodes

This code signifies a specific type of non-Hodgkin lymphoma, follicular lymphoma, which is characterized by a grade II cellular differentiation. The disease is located within the lymph nodes found inside the abdominal cavity. This indicates a moderate-grade malignancy originating from B-lymphocytes.

Assign this code when diagnostic pathology reports confirm follicular lymphoma, grade II, and imaging or surgical findings specify involvement of intra-abdominal lymph nodes. Documentation should clearly state both the histological grade and the anatomical location of the affected lymph nodes.

• Ensure the pathology report explicitly states "grade II" for follicular lymphoma; do not assume the grade.
• Verify the anatomical site is "intra-abdominal lymph nodes" and not other abdominal organs or extra-abdominal sites.
• This code requires confirmation of the specific lymphoma type and grade, typically from a biopsy.
