A less common type of Hodgkin lymphoma affecting lymph nodes in the groin and lower legs.
Coding Tips
- •Confirm inguinal and/or lower limb node involvement through imaging or pathology
- •Document unilateral vs. bilateral involvement for complete staging information
Clinical Significance
Other Hodgkin lymphoma involving inguinal and lower limb lymph nodes is a rare presentation combining an uncommon subtype with an infradiaphragmatic site. Inguinal lymphadenopathy has a broad differential diagnosis, and biopsy confirmation is essential. The 'other' Hodgkin variant designation indicates the histology does not match any standard classical Hodgkin subtype.
Documentation Requirements
- ✓Pathology confirming Hodgkin lymphoma with 'other' subtype from inguinal or lower limb node biopsy
- ✓Physical exam or imaging documenting inguinal or lower limb node involvement
- ✓Documentation of unilateral versus bilateral involvement
- ✓Staging workup including assessment for additional nodal and extranodal disease
- ✓Provider assessment and management plan
