0.000What This Code Means
A type of Hodgkin lymphoma (blood cancer) with nodular sclerosis pattern that has spread to lymph nodes in the abdomen.
Coding Tips
- •The fifth character '3' specifically indicates intra-abdominal lymph node involvement; ensure imaging or pathology confirms abdominal location
- •This code requires a seventh character for remission status (A for initial encounter, D for subsequent encounter, S for sequela)
Clinical Significance
Nodular sclerosis Hodgkin lymphoma of intra-abdominal lymph nodes indicates disease affecting mesenteric, retroperitoneal, or para-aortic lymph nodes in the abdomen. Abdominal involvement is less common than cervical or mediastinal disease in nodular sclerosis Hodgkin lymphoma and typically indicates Stage III or higher disease requiring systemic chemotherapy. Infradiaphragmatic-only presentation is uncommon and warrants careful staging.
Documentation Requirements
- ✓Pathology confirming nodular sclerosis subtype
- ✓Cross-sectional imaging documenting specific abdominal lymph node groups
- ✓Assessment of whether abdominal disease is isolated or combined with supradiaphragmatic disease
- ✓Ann Arbor staging reflecting abdominal involvement
- ✓Treatment plan appropriate for advanced stage disease
- ✓B-symptoms assessment
