0.000What This Code Means
A type of cancer affecting B-cells in the lymph nodes located within the pelvis.
Coding Tips
- •Ensure documentation clearly indicates intrapelvic (within the pelvis) lymph node involvement
- •Do not confuse with inguinal lymph nodes which are in the groin area
Clinical Significance
Mantle cell lymphoma of intrapelvic lymph nodes involves deep pelvic node chains including iliac, obturator, and sacral nodes. These are typically identified on cross-sectional imaging rather than physical examination and may cause urological or gynecological symptoms through mass effect on adjacent pelvic organs.
Documentation Requirements
- ✓Pathology-confirmed mantle cell lymphoma diagnosis
- ✓CT or MRI pelvis documenting intrapelvic lymph node involvement
- ✓Specific pelvic node groups identified (iliac, obturator, sacral)
- ✓Assessment for mass effect on pelvic organs (bladder, ureters, rectum)
- ✓Complete staging workup documenting extent of disease
Commonly Confused Codes
C83.15 — Mantle cell lymphoma, inguinal/lower limb; inguinal nodes are superficial groin nodes, not deep pelvic nodesC83.13 — Mantle cell lymphoma, intra-abdominal; the pelvic brim divides abdominal from pelvic node classificationC83.19 — Extranodal/solid organ sites; pelvic organ (bladder, prostate) involvement is extranodal, not nodal
