0.000What This Code Means
A type of blood cancer affecting immature lymphoid cells located in the lymph nodes within the chest cavity.
Coding Tips
- •Confirm documentation indicates intrathoracic (within the chest) lymph node involvement
- •This includes mediastinal and other thoracic lymph nodes; do not use for lung parenchymal involvement
Clinical Significance
Lymphoblastic lymphoma of intrathoracic lymph nodes is particularly important because T-cell lymphoblastic lymphoma frequently presents as a mediastinal (thymic) mass in adolescents and young adults. This presentation can cause airway compromise, superior vena cava syndrome, and pleural effusions, requiring urgent evaluation and sometimes emergency treatment initiation.
Documentation Requirements
- ✓Pathology confirmation with TdT and T-cell or B-cell lineage markers
- ✓CT chest documenting mediastinal mass or intrathoracic lymphadenopathy
- ✓Assessment for airway compromise or superior vena cava syndrome
- ✓Bone marrow biopsy to distinguish from leukemia
- ✓CNS evaluation and pleural fluid analysis if effusion present
Commonly Confused Codes
C85.22 — Mediastinal large B-cell lymphoma, intrathoracic; mature B-cell lymphoma vs. immature precursorC83.32 — DLBCL, intrathoracic; mature large B-cell vs. immature lymphoblasticC83.72 — Burkitt lymphoma, intrathoracic; different biology despite both being aggressiveC91.00 — Acute lymphoblastic leukemia; bone marrow blasts >25% indicates leukemia
