ICD-10 Code C81.92 – Hodgkin lymphoma, unspecified, intrathoracic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.92 – Hodgkin lymphoma, unspecified, intrathoracic lymph nodes
What it is
This code identifies Hodgkin lymphoma involving intrathoracic lymph nodes when the specific type is not documented. Use it for a malignant lymphoid neoplasm affecting nodes in the chest.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include enlarged intrathoracic lymph nodes seen on imaging, with or without systemic lymphoma symptoms such as fever, weight loss, or night sweats.
When to use this code
Use C81.92 when the record states Hodgkin lymphoma and specifies intrathoracic lymph nodes, but does not identify a more specific subtype. It is appropriate for confirmed diagnoses involving mediastinal, hilar, or other chest nodes. If the site or histology is more specific, code that documentation instead.
Do not use for
Do not use this code for non-Hodgkin lymphoma, other Hodgkin lymphoma sites, or unspecified lymphoma without intrathoracic node involvement. Check documentation if the diagnosis only mentions lymphadenopathy or a suspected mass.
Coding tip
Match the code to both the Hodgkin diagnosis and the documented intrathoracic nodal site before assigning it.
