0.000What This Code Means
Hodgkin lymphoma with nodular lymphocyte predominance located in the lymph nodes within the pelvis.
Coding Tips
- •Confirm intrapelvic location is documented; this includes pelvic lymph nodes but not inguinal nodes
- •Distinguish from C81.05 which includes inguinal region involvement
Clinical Significance
Nodular lymphocyte predominant Hodgkin lymphoma involving intrapelvic lymph nodes indicates disease in deep pelvic lymph node groups (iliac, obturator, sacral). This is an uncommon presentation for NLPHL and may be discovered on cross-sectional imaging rather than physical exam. Intrapelvic disease is typically classified as infradiaphragmatic and may indicate Stage II or higher depending on other sites of involvement.
Documentation Requirements
- ✓Pathology confirming NLPHL subtype
- ✓Cross-sectional imaging (CT or PET/CT) documenting intrapelvic lymph node involvement
- ✓Distinction from inguinal (superficial groin) lymph nodes
- ✓Specific pelvic lymph node groups involved (iliac, obturator, sacral)
- ✓Complete staging workup including above-diaphragm assessment
- ✓Treatment plan reflecting pelvic involvement
Commonly Confused Codes
C81.05 — NLPHL, inguinal region and lower limb: Inguinal nodes are superficial groin nodes; intrapelvic are deep pelvic nodesC81.03 — NLPHL, intra-abdominal lymph nodes: Pelvic nodes are anatomically distinct from abdominal nodesC81.16 — Nodular sclerosis Hodgkin lymphoma, intrapelvic: Different subtype; confirm pathologyC81.00 — NLPHL, unspecified site: Use C81.06 when pelvic lymph node involvement is documented
