0.000What This Code Means
A type of non-follicular lymphoma affecting the lymph nodes within the pelvis.
Coding Tips
- •Intrapelvic lymph nodes include iliac, obturator, and other pelvic lymph nodes
- •Ensure documentation confirms pelvic lymph node involvement before assigning this code
Clinical Significance
Other non-follicular lymphoma of intrapelvic lymph nodes involves iliac, obturator, presacral, or other pelvic lymph node chains. Pelvic lymphoma can mimic or coexist with gynecologic or urologic malignancies, making accurate pathologic diagnosis essential. Intrapelvic presentations may cause urinary or bowel obstruction requiring urgent intervention.
Documentation Requirements
- ✓Pathology confirming non-follicular lymphoma subtype
- ✓Pelvic imaging (CT, PET/CT, or MRI) documenting intrapelvic lymph node involvement
- ✓Specification of pelvic lymph node chain (iliac, obturator, presacral) if documented
- ✓Assessment for complications such as ureteral obstruction or venous compression
- ✓Staging and treatment plan documentation
Commonly Confused Codes
C83.85 — Other non-follicular lymphoma, inguinal/lower limb: Inguinal nodes are superficial to the pelvis; intrapelvic nodes are within the pelvic cavity — distinct anatomic locationsC83.96 — Non-follicular (diffuse) lymphoma, unspecified, intrapelvic: C83.86 indicates a known 'other' subtype; C83.96 is for unspecified subtypeC83.83 — Other non-follicular lymphoma, intra-abdominal: Abdominal nodes are above the pelvic brim; intrapelvic nodes are below
