0.000What This Code Means
A type of non-Hodgkin lymphoma affecting the skin and follicle center cells in the lymph nodes within the chest cavity.
Coding Tips
- •Verify intrathoracic (within chest) lymph node involvement is documented
- •Differentiate from other thoracic lymphomas by confirming cutaneous follicle center origin
Clinical Significance
Cutaneous follicle center lymphoma with intrathoracic lymph node involvement is an unusual presentation suggesting potential systemic spread of what is typically a localized primary cutaneous lymphoma. Intrathoracic nodal disease in the setting of a cutaneous lymphoma should prompt reconsideration of whether this is truly primary cutaneous disease or secondary cutaneous involvement by a systemic follicular lymphoma, as the distinction affects treatment and prognosis.
Documentation Requirements
- ✓Skin biopsy confirming cutaneous follicle center lymphoma origin
- ✓Chest imaging documenting intrathoracic lymph node involvement
- ✓Clinical correlation establishing the skin as the primary site of disease
- ✓Immunohistochemistry supporting cutaneous origin (BCL2 status)
- ✓Complete staging evaluation to assess extent of systemic disease
Commonly Confused Codes
C82.52 — Diffuse follicle center lymphoma, intrathoracic lymph nodes: Use when the lymphoma is systemic (not cutaneous origin)C82.82 — Other types of follicular lymphoma, intrathoracic lymph nodes: Use only when the specific follicular lymphoma type differsC82.68 — Cutaneous follicle center lymphoma, lymph nodes of multiple sites: If intrathoracic nodes are one of several involved sites, consider the multi-site code
