ICD-10 Code C85.82 – Other specified types of non-Hodgkin lymphoma, intrathoracic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C85.82 – Other specified types of non-Hodgkin lymphoma, intrathoracic lymph nodes
What it is
This code identifies a non-Hodgkin lymphoma described as “other specified” and involving intrathoracic lymph nodes. Use it when the record names a qualifying lymphoma type but not a more specific category.
Clinical signs
Findings may include enlarged mediastinal or hilar lymph nodes, cough, chest discomfort, dyspnea, or incidental imaging abnormalities. Clinical features vary; refer to documentation.
When to use this code
Use C85.82 when the provider documents an other specified non-Hodgkin lymphoma affecting intrathoracic lymph nodes and no more specific code applies. It is appropriate for pathology, oncology, or discharge documentation that clearly identifies this site. If the lymphoma type or site is unclear, check documentation.
Do not use for
Do not use this code for unspecified non-Hodgkin lymphoma, lymphoma in other nodal regions, or Hodgkin lymphoma. If the record does not support intrathoracic node involvement, choose a different code.
Coding tip
Confirm both the lymphoma description and the intrathoracic nodal site in the provider note before assigning this code.
