BillableFollicular lymphoma grade IIIa, lymph nodes of axilla and upper limb
HCC Category Mapping
What This Code Means
A type of blood cancer (follicular lymphoma grade IIIa) affecting lymph nodes in the armpits and upper arms. Grade IIIa is a more aggressive form of this cancer.
Coding Tips
- •Confirm axillary and upper limb lymph node involvement is documented in imaging or pathology
- •This site is often detected on physical examination or imaging studies
Clinical Significance
Follicular lymphoma grade IIIa of axillary and upper limb lymph nodes represents a specific high-grade subtype at a commonly involved peripheral site. The IIIa designation (centrocytes present) has treatment implications — some oncologists treat IIIa like indolent lymphoma while others use aggressive chemoimmunotherapy. Axillary disease is readily monitored on physical exam.
Documentation Requirements
- ✓Pathology confirming grade IIIa follicular lymphoma with centrocytes present
- ✓Documentation of axillary/upper limb lymph node involvement
- ✓Laterality
- ✓Ann Arbor staging
- ✓Treatment rationale for chosen approach (indolent vs. aggressive management)
