0.000What This Code Means
A type of blood cancer (non-follicular lymphoma) that has spread to the lymph nodes in the pelvis area.
Coding Tips
- •Verify the pathology report confirms non-follicular (diffuse) lymphoma type before coding
- •The '6' indicates intrapelvic lymph node involvement; ensure imaging or clinical documentation supports this specific site
Clinical Significance
Non-follicular (diffuse) lymphoma, unspecified type, of intrapelvic lymph nodes represents lymphoma within the pelvic cavity involving iliac, obturator, or presacral lymph nodes, without specific subtype determination. Pelvic lymphoma may present with lower abdominal or pelvic symptoms and can be challenging to diagnose without cross-sectional imaging. This code captures the site while indicating the need for further pathologic subtyping.
Documentation Requirements
- ✓Pelvic imaging (CT, MRI, or PET/CT) documenting intrapelvic lymphadenopathy
- ✓Biopsy results confirming lymphoma — query for specific subtype
- ✓Distinction between intrapelvic and inguinal lymph node involvement
- ✓Assessment for local complications (ureteral obstruction, nerve compression)
- ✓Staging and treatment documentation
Commonly Confused Codes
C83.86 — Other non-follicular lymphoma, intrapelvic: C83.86 is for a known 'other' subtype; C83.96 is for unspecified subtypeC83.95 — Non-follicular lymphoma, unspecified, inguinal/lower limb: Inguinal nodes are superficial; intrapelvic nodes are deep within the pelvisC83.93 — Non-follicular lymphoma, unspecified, intra-abdominal: Abdominal nodes are above the pelvic brim; intrapelvic are below
