Follicular lymphoma affecting lymph nodes in the armpit and upper arm region.
Coding Tips
- •This code includes axillary and upper limb lymph node involvement
- •Distinguish between unilateral and bilateral involvement if documented
Clinical Significance
Follicular lymphoma, unspecified type, involving axillary and upper limb lymph nodes captures follicular lymphoma in the armpit and upper extremity region without grade specification. Axillary lymphadenopathy is a very common presentation site for lymphoma and must be distinguished from metastatic breast cancer and reactive causes. The unspecified grade should prompt a pathology query to enable more specific coding.
Documentation Requirements
- ✓Pathology confirming follicular lymphoma
- ✓Documentation of axillary and/or upper limb lymph node involvement
- ✓Laterality (right, left, or bilateral)
- ✓Imaging with measurements
- ✓Query for grade determination from pathology
- ✓Assessment for upper extremity lymphedema
