Follicular lymphoma grade II, intrapelvic lymph nodes

This code signifies a specific type of non-Hodgkin lymphoma, follicular lymphoma, which is characterized by a grade II cellular differentiation. The diagnosis further specifies the anatomical location of the cancerous lymph nodes as intrapelvic. This indicates involvement of lymph nodes situated within the pelvic cavity.

This code is appropriate when documentation confirms a diagnosis of follicular lymphoma, specifically graded as II, and the disease is localized to lymph nodes within the pelvis. Supporting documentation would include pathology reports confirming the follicular lymphoma and grade, along with imaging or surgical reports detailing intrapelvic lymph node involvement.

• Ensure the pathology report explicitly states "follicular lymphoma, grade II." Do not assume the grade if not documented.
• Verify the anatomical site of involvement is clearly documented as "intrapelvic lymph nodes" to differentiate from other nodal sites.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, unless another condition is clearly identified as the principal diagnosis.
