ICD-10 Code C81.72 – Other Hodgkin lymphoma, intrathoracic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.72 – Other Hodgkin lymphoma, intrathoracic lymph nodes
What it is
This code identifies Hodgkin lymphoma involving the intrathoracic lymph nodes, such as mediastinal or hilar nodes, when the type is classified as other Hodgkin lymphoma. Use it for documented disease in this thoracic nodal region.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include enlarged intrathoracic lymph nodes on imaging, chest symptoms, or biopsy-confirmed Hodgkin lymphoma affecting thoracic nodes.
When to use this code
Use C81.72 when the record clearly states other Hodgkin lymphoma with intrathoracic lymph node involvement. It is appropriate when pathology, imaging, or specialist notes specify mediastinal, hilar, or other thoracic nodal disease. If the site or lymphoma subtype is unclear, check documentation before coding.
Do not use for
Do not use this code for Hodgkin lymphoma limited to non-thoracic nodes or for unspecified lymph node sites. If the chart does not confirm the intrathoracic location, choose a more accurate documented code.
Coding tip
Verify both the Hodgkin subtype and the intrathoracic nodal site in the same note before assigning C81.72.
