0.000What This Code Means
A type of blood cancer (non-follicular lymphoma) that has spread to lymph nodes in multiple different areas of the body.
Coding Tips
- •Use this code when lymphoma involves lymph nodes at two or more distinct anatomical regions
- •Document which specific regions are involved in the medical record for clinical clarity
Clinical Significance
Non-follicular (diffuse) lymphoma, unspecified type, involving multiple lymph node sites indicates widespread nodal disease without a specified subtype. Multi-site involvement typically corresponds to advanced staging and requires systemic therapy. This code captures both the disseminated nature of the disease and the need for further pathologic classification.
Documentation Requirements
- ✓Imaging documenting lymph node involvement at two or more distinct anatomic regions
- ✓Pathology — query for specific non-follicular subtype
- ✓List of involved lymph node regions
- ✓Staging reflecting multi-site disease (typically Ann Arbor Stage III or IV)
- ✓Treatment plan for advanced-stage lymphoma
Commonly Confused Codes
C83.88 — Other non-follicular lymphoma, multiple sites: C83.88 is for a known 'other' subtype; C83.98 is for unspecified subtypeC83.91-C83.97 — Single-site codes: Use only when disease is limited to one lymph node regionC83.99 — Non-follicular lymphoma, unspecified, extranodal: C83.98 is for multiple nodal sites; C83.99 is for solid organ involvement
