Follicular lymphoma affecting lymph nodes in the groin and lower leg region.
Coding Tips
- •This code includes inguinal and lower limb lymph node involvement
- •Document whether involvement is unilateral or bilateral for complete clinical picture
Clinical Significance
Follicular lymphoma, unspecified type, involving inguinal and lower limb lymph nodes captures follicular lymphoma in the groin and leg region without grade specification. Inguinal lymphadenopathy must be differentiated from the common reactive inguinal adenopathy and metastatic disease from lower extremity or genitourinary cancers. The unspecified grade designation should prompt a pathology query for grade information to support more precise coding.
Documentation Requirements
- ✓Pathology confirming follicular lymphoma
- ✓Documentation of inguinal and/or lower limb lymph node involvement
- ✓Laterality of involvement
- ✓Imaging confirmation with measurements
- ✓Query for grade determination
- ✓Assessment for lower extremity edema or deep vein thrombosis
