0.000What This Code Means
A type of non-follicular lymphoma affecting the lymph nodes in the groin area and lower legs.
Coding Tips
- •This includes inguinal lymph nodes and lymph nodes of the lower extremities
- •Specify if involvement is in the groin, thigh, or lower leg area when possible
Clinical Significance
Other non-follicular lymphoma of inguinal region and lower limb lymph nodes affects the groin and lower extremity lymphatic drainage. Inguinal lymphoma is less common than axillary or cervical presentations and must be differentiated from reactive inguinal lymphadenopathy or metastatic disease from pelvic or lower extremity malignancies. Accurate coding supports proper staging and risk assessment.
Documentation Requirements
- ✓Pathology report confirming non-follicular lymphoma from inguinal or lower limb lymph node biopsy
- ✓Physical exam or imaging documenting inguinal or lower limb lymph node involvement
- ✓Laterality if specified (right vs. left)
- ✓Assessment for concurrent pelvic or abdominal lymph node involvement
- ✓Treatment status and staging documentation
