0.000What This Code Means
A type of slow-growing blood cancer (follicular lymphoma) that is grade III and located in the lymph nodes of the armpit and upper arm area.
Coding Tips
- •Axillary lymph nodes are the primary nodes in this region; document if unilateral or bilateral
- •Verify that upper limb involvement is confirmed by imaging or pathology
Clinical Significance
Follicular lymphoma grade III unspecified in axillary and upper limb lymph nodes combines higher-grade histology with a commonly involved peripheral site. Axillary grade III disease may present with rapid nodal growth compared to indolent grades, prompting biopsy to rule out transformation. This code captures the clinical urgency of grade III disease in an accessible location.
Documentation Requirements
- ✓Pathology confirming grade III follicular lymphoma (>15 centroblasts per HPF)
- ✓Documentation of axillary and/or upper limb lymph node involvement
- ✓Laterality documentation
- ✓Query for IIIa vs. IIIb subtype
- ✓Assessment for rapid growth suggesting transformation
Commonly Confused Codes
C82.14 — Grade II, axilla/upper limb; lower grade, verify centroblast countC82.34 — Grade IIIa of same site; use when pathology specifies subtypeC82.44 — Grade IIIb of same site; use for centroblast-only patternC83.34 — Diffuse large B-cell lymphoma, axilla/upper limb; if transformation has occurred
