0.000What This Code Means
A type of blood cancer (non-follicular lymphoma) affecting the lymph nodes inside the chest cavity.
Coding Tips
- •Verify chest imaging (CT or PET scan) confirms intrathoracic lymph node involvement
- •Note if mediastinal or hilar nodes are specifically involved
Clinical Significance
Non-follicular (diffuse) lymphoma, unspecified type, of intrathoracic lymph nodes indicates lymphoma within the chest cavity where the specific non-follicular subtype has not been determined. Intrathoracic lymphoma may be discovered incidentally on chest imaging or present with symptoms of chest discomfort, cough, or superior vena cava syndrome. Subtype identification through biopsy is critical for treatment selection.
Documentation Requirements
- ✓Chest imaging (CT or PET/CT) documenting intrathoracic lymphadenopathy
- ✓Pathology report — query for specific subtype if only 'lymphoma' is documented
- ✓Assessment for mass effect or complications (airway compression, effusions)
- ✓Treatment plan and staging
- ✓Disease status and response to therapy if applicable
