A mature T-cell or natural killer cell lymphoma affecting the lymph nodes inside the chest cavity.
Coding Tips
- •Verify intrathoracic lymph node involvement through imaging or pathology documentation
- •Distinguish between mediastinal and other intrathoracic lymph node locations if clinically relevant
Clinical Significance
Mature T/NK-cell lymphomas, unspecified, involving intrathoracic lymph nodes indicates unclassified T-cell or NK-cell lymphoma with mediastinal or hilar nodal disease. Intrathoracic lymphadenopathy can cause respiratory compromise and cardiovascular compression. Efforts should be made to obtain tissue for more specific classification.
Documentation Requirements
- ✓Pathology confirming mature T-cell or NK-cell lymphoma
- ✓Chest imaging documenting intrathoracic lymph node involvement
- ✓Immunophenotyping results
- ✓Documentation of attempts to further classify the lymphoma subtype
- ✓Clinical staging
