0.000What This Code Means
Follicular lymphoma affecting lymph nodes within the chest cavity.
Coding Tips
- •This code applies to mediastinal and other intrathoracic lymph node involvement
- •Verify imaging or pathology reports document intrathoracic lymph node involvement
Clinical Significance
Follicular lymphoma, unspecified type, involving intrathoracic lymph nodes captures follicular lymphoma in the chest cavity when the specific grade has not been determined. Intrathoracic lymphoma may cause respiratory symptoms or be discovered incidentally on chest imaging. The unspecified grade should trigger a pathology review to determine if grading information is available, as this impacts treatment decisions and allows more precise coding.
Documentation Requirements
- ✓Pathology confirming follicular lymphoma without grade specification
- ✓Chest imaging documenting intrathoracic lymph node involvement
- ✓Specification of involved nodal stations (mediastinal, hilar, paratracheal)
- ✓Query to pathology for grade determination
- ✓Assessment for compressive symptoms
