0.000What This Code Means
A type of blood cancer (non-follicular lymphoma) affecting the lymph nodes in the abdominal cavity.
Coding Tips
- •Confirm abdominal imaging documents lymph node involvement
- •Specify if retroperitoneal, mesenteric, or other abdominal lymph nodes are affected
Clinical Significance
Non-follicular (diffuse) lymphoma, unspecified type, of intra-abdominal lymph nodes represents lymphoma within the abdominal cavity where the specific subtype has not been classified. Abdominal lymphoma may present with vague symptoms such as abdominal pain, weight loss, or bowel changes. This code captures the site specificity while indicating a need for further pathologic characterization.
Documentation Requirements
- ✓Abdominal imaging documenting lymphadenopathy
- ✓Pathology report — query for specific subtype if available
- ✓Specification of abdominal lymph node chain involved if documented
- ✓Clinical presentation and symptom documentation
- ✓Staging and treatment plan
