0.000What This Code Means
A specific type of Hodgkin lymphoma affecting the lymph nodes inside the abdominal cavity.
Coding Tips
- •Confirm documentation specifies intra-abdominal lymph node involvement rather than other abdominal organs
- •Verify imaging or pathology reports document lymph node location within the abdomen
Clinical Significance
Nodular lymphocyte predominant Hodgkin lymphoma involving intra-abdominal lymph nodes indicates disease affecting mesenteric, retroperitoneal, or other abdominal lymph node groups. Abdominal involvement in NLPHL is relatively uncommon and may suggest more advanced disease requiring systemic therapy rather than localized radiation. Abdominal NLPHL may present with vague abdominal symptoms or be discovered incidentally on imaging.
Documentation Requirements
- ✓Pathology confirming NLPHL subtype
- ✓Cross-sectional imaging (CT abdomen/pelvis or PET/CT) documenting specific abdominal lymph node groups involved
- ✓Ann Arbor staging classification
- ✓Assessment of whether abdominal involvement represents infradiaphragmatic disease only or combined with supradiaphragmatic disease
- ✓Treatment plan reflecting the stage and extent of disease
Commonly Confused Codes
C81.13 — Nodular sclerosis Hodgkin lymphoma, intra-abdominal: Different subtype; verify pathologyC81.00 — NLPHL, unspecified site: Use C81.03 when abdominal lymph node involvement is documentedC81.06 — NLPHL, intrapelvic lymph nodes: Distinguish between intra-abdominal and intrapelvic locationsC82.03 — Follicular lymphoma, intra-abdominal: Different lymphoma subtype entirely
