A type of cancer of the lymph system (follicular lymphoma) affecting multiple lymph node regions throughout the body without specification of grade or stage.
Coding Tips
Clinical Significance
Follicular lymphoma, unspecified type, involving lymph nodes at multiple sites represents widespread follicular lymphoma without grade determination. Multi-site nodal disease indicates at least stage III disease and generally requires systemic treatment. The unspecified grade is a documentation gap that should prompt a pathology query, as follicular lymphoma grade directly impacts prognosis and treatment approach (watchful waiting for grade I-II vs. immediate treatment for grade IIIb).
Documentation Requirements
- ✓Pathology confirming follicular lymphoma
- ✓Imaging documenting involvement of at least two distinct anatomic nodal regions
- ✓Specification of all involved nodal regions
- ✓Query for grade determination from pathology
- ✓Staging documentation reflecting multi-site involvement
- ✓Treatment plan
Commonly Confused Codes
C82.88 — Other types of follicular lymphoma, lymph nodes of multiple sites: Use when a specific variant is identifiedC82.99 — Follicular lymphoma, unspecified, extranodal and solid organ sites: Distinguish nodal multi-site from extranodal involvementC82.90 — Follicular lymphoma, unspecified, unspecified site: Even less specific; use C82.98 when multiple sites are documented
