0.000What This Code Means
A type of blood cancer (non-follicular lymphoma) affecting the lymph nodes in the groin and lower legs.
Coding Tips
- •Confirm inguinal and lower limb lymph node involvement through examination or imaging
- •Note if involvement is unilateral or bilateral for staging documentation
Clinical Significance
Non-follicular (diffuse) lymphoma, unspecified type, of inguinal region and lower limb lymph nodes captures lymphoma involving the groin and lower extremity lymph nodes without a specified subtype. Inguinal lymphoma is less common and must be distinguished from reactive lymphadenopathy or metastatic disease from pelvic or lower extremity primary cancers. Subtype determination through biopsy is important for treatment selection.
Documentation Requirements
- ✓Physical examination or imaging confirming inguinal or lower limb lymphadenopathy
- ✓Biopsy confirming lymphoma — query for specific non-follicular subtype
- ✓Laterality if documented
- ✓Assessment for concurrent pelvic disease
- ✓Staging and treatment plan
Commonly Confused Codes
C83.85 — Other non-follicular lymphoma, inguinal/lower limb: C83.85 is for a known 'other' subtype; C83.95 is for unspecified subtypeC83.96 — Non-follicular lymphoma, unspecified, intrapelvic: Distinct from inguinal; intrapelvic nodes are within the pelvic cavityC77.4 — Secondary malignant neoplasm, inguinal lymph nodes: Use for metastatic disease, not primary lymphoma
