0.000What This Code Means
A type of cancer of the lymph system (follicular lymphoma) that is grade IIIa and located in the lymph nodes of the groin and lower leg area.
Coding Tips
- •Ensure the grade (IIIa) and specific anatomical site (inguinal region and lower limb) are documented in the medical record before coding
- •This code is more specific than unspecified site codes; verify documentation supports the inguinal/lower limb location
Clinical Significance
Follicular lymphoma grade IIIa involving inguinal and lower limb lymph nodes combines a specific high-grade subtype with a common peripheral nodal site. Grade IIIa in the inguinal region may present with significant lymphadenopathy but retains the centrocyte component that distinguishes it from the more aggressive IIIb pattern. Treatment decisions should reference the grade subtype.
Documentation Requirements
- ✓Pathology confirming grade IIIa follicular lymphoma
- ✓Physical exam or imaging documenting inguinal/lower limb involvement
- ✓Laterality
- ✓Ann Arbor staging
- ✓Treatment plan with rationale for intensity level
