Hodgkin lymphoma of unspecified type affecting lymph nodes inside the chest cavity.
Coding Tips
- •Verify documentation indicates intrathoracic (mediastinal or hilar) lymph node involvement
- •Distinguish from lung parenchymal involvement, which would be coded differently
Clinical Significance
Hodgkin lymphoma of unspecified type affecting intrathoracic lymph nodes captures a confirmed Hodgkin diagnosis in the chest without histologic subtype information. Mediastinal lymphadenopathy from Hodgkin lymphoma is very common, particularly in young adults, and may cause compressive symptoms. The subtype should be determined from pathology to guide treatment decisions.
Documentation Requirements
- ✓Confirmed Hodgkin lymphoma diagnosis
- ✓Chest imaging documenting intrathoracic (mediastinal, hilar) lymph node involvement
- ✓Explanation for why subtype is not specified (e.g., pending pathology review, outside records)
- ✓Assessment for compressive complications
- ✓Treatment or workup plan
Commonly Confused Codes
C81.12 — Nodular sclerosis Hodgkin lymphoma, intrathoracic: the most common subtype in the mediastinum; use when pathology confirmsC81.72 — Other Hodgkin lymphoma, intrathoracic: pathology reviewed but does not fit standard categoriesC85.22 — Mediastinal large B-cell lymphoma: a distinct non-Hodgkin entity
