What This Code Means

A type of cancer of the lymph system (follicular lymphoma) that is grade IIIa and affects lymph nodes in multiple different areas of the body.

Coding Tips

•Use this code when the lymphoma involves two or more separate lymph node regions
•Document all affected sites in the medical record to support the 'multiple sites' designation

Clinical Significance

Follicular lymphoma grade IIIa involving multiple lymph node sites represents widespread high-grade disease with centrocytes present. This presentation is common and typically requires systemic chemoimmunotherapy. The IIIa subtype identification is clinically relevant as some centers may offer different treatment intensities for IIIa versus IIIb.

Documentation Requirements

✓Pathology confirming grade IIIa follicular lymphoma
✓PET/CT documenting all involved lymph node regions
✓Complete list of involved anatomic sites
✓FLIPI score and performance status
✓Treatment plan with chemoimmunotherapy regimen selected

Commonly Confused Codes

C82.28 — Grade III unspecified, multiple sites; use C82.38 when IIIa is confirmed C82.39 — Grade IIIa, extranodal; for organ involvement, not nodal C82.48 — Grade IIIb, multiple sites; IIIb has centroblasts only C83.38 — Diffuse large B-cell lymphoma, multiple sites; different entity
