Hodgkin lymphoma of unspecified type affecting lymph nodes in the abdominal cavity.
Coding Tips
- •Ensure documentation specifies intra-abdominal lymph nodes, not solid organ involvement
- •If spleen is involved, consider whether C81.77 might be more appropriate
Clinical Significance
Hodgkin lymphoma of unspecified type involving intra-abdominal lymph nodes captures an abdominal presentation without histologic subtype information. Infradiaphragmatic Hodgkin lymphoma is less common than supradiaphragmatic and may present with nonspecific abdominal symptoms. The site specificity is documented but the histologic subtype requires pathology review for classification.
Documentation Requirements
- ✓Confirmed Hodgkin lymphoma diagnosis
- ✓Imaging documenting intra-abdominal lymph node involvement
- ✓Distinction from intrapelvic and splenic involvement
- ✓Plan to determine histologic subtype from pathology
- ✓Encounter-specific provider assessment
