0.000What This Code Means
A type of non-Hodgkin lymphoma affecting the skin and follicle center cells in the lymph nodes within the abdomen.
Coding Tips
- •Ensure documentation specifies intra-abdominal lymph node involvement
- •Confirm cutaneous component is present to justify this specific code
Clinical Significance
Cutaneous follicle center lymphoma involving intra-abdominal lymph nodes represents an atypical spread pattern for a primary cutaneous lymphoma. This should raise clinical suspicion that the disease may have been misclassified and may actually represent systemic follicular lymphoma with secondary cutaneous involvement. Proper classification is important because primary cutaneous and systemic follicular lymphomas have markedly different prognoses and treatment approaches.
Documentation Requirements
- ✓Skin biopsy with pathology confirming primary cutaneous follicle center lymphoma
- ✓Abdominal imaging documenting intra-abdominal lymph node involvement
- ✓Clinical rationale for maintaining primary cutaneous classification despite abdominal nodal disease
- ✓Immunohistochemistry results supporting cutaneous origin
- ✓Staging documentation reflecting both cutaneous and abdominal findings
