A type of non-follicular lymphoma affecting the lymph nodes in the armpits and upper arms.
Coding Tips
- •This includes axillary lymph nodes and lymph nodes of the upper extremities
- •Document whether involvement is unilateral or bilateral for complete clinical picture
Clinical Significance
Other non-follicular lymphoma involving axillary and upper limb lymph nodes represents disease affecting a common lymph node drainage basin. Axillary lymphadenopathy from lymphoma must be distinguished from reactive lymphadenopathy or metastatic disease from breast or upper extremity malignancies. This site-specific code supports accurate staging and treatment planning documentation.
Documentation Requirements
- ✓Pathology confirming non-follicular lymphoma subtype from axillary or upper limb node biopsy
- ✓Physical examination or imaging confirming axillary or upper limb lymph node involvement
- ✓Laterality documentation (unilateral vs. bilateral) if available
- ✓Staging information and whether disease extends beyond this region
- ✓Current treatment status
