What This Code Means

A type of slow-growing blood cancer (follicular lymphoma) that is grade III and located in the lymph nodes inside the abdominal cavity.

Coding Tips

  • Intra-abdominal lymph nodes include mesenteric, retroperitoneal, and other abdominal nodes
  • Imaging studies (CT or PET scan) should document the specific abdominal lymph node involvement

Clinical Significance

Follicular lymphoma grade III unspecified in intra-abdominal lymph nodes indicates high-grade disease in the mesenteric, retroperitoneal, or para-aortic chains. Grade III abdominal disease may present with abdominal pain, early satiety, or bowel symptoms and typically requires treatment rather than observation. This is a more aggressive clinical scenario than low-grade abdominal disease.

Documentation Requirements

  • Pathology confirming grade III follicular lymphoma
  • Cross-sectional imaging with specific abdominal node measurements
  • Assessment for GI complications (obstruction, perforation risk)
  • Query for IIIa vs. IIIb specification
  • Treatment plan reflecting grade III aggressiveness
