What This Code Means

A type of skin cancer (mycosis fungoides) that has spread to lymph nodes in multiple different areas of the body.

Coding Tips

  • Use this code only when mycosis fungoides involves lymph nodes at two or more distant sites
  • Document which specific lymph node regions are involved for complete clinical picture

Clinical Significance

Mycosis fungoides involving lymph nodes at multiple sites indicates widespread nodal disease representing advanced-stage cutaneous T-cell lymphoma. Multi-site lymph node involvement significantly worsens prognosis and necessitates systemic therapy. This presentation reflects transformation from localized cutaneous disease to disseminated lymphoma requiring intensive management.

Documentation Requirements

  • Skin biopsy confirming mycosis fungoides
  • Imaging documenting lymph node involvement at two or more distinct anatomic regions
  • Pathologic confirmation of lymphomatous involvement in at least one site
  • TNMB staging reflecting multi-site nodal disease
  • Systemic treatment plan
