0.000What This Code Means
A type of blood cancer affecting immature lymphoid cells located in the lymph nodes of the armpit and upper arm region.
Coding Tips
- •Verify documentation indicates axillary or upper limb lymph node involvement
- •This includes nodes in the shoulder and upper extremity regions
Clinical Significance
Lymphoblastic lymphoma of axillary and upper limb lymph nodes is an uncommon isolated site presentation. Axillary lymphoblastic lymphoma should prompt urgent bone marrow assessment to exclude leukemic transformation and comprehensive staging to assess for other sites of involvement, as this aggressive lymphoma frequently disseminates rapidly.
Documentation Requirements
- ✓Pathology confirmation with TdT and lineage markers from axillary node biopsy
- ✓Documentation specifying axillary and/or upper limb lymph node involvement
- ✓Laterality documentation
- ✓Bone marrow biopsy results
- ✓Complete staging workup including CNS evaluation
