ICD-10 Code C81.02 – Nodular lymphocyte predominant Hodgkin lymphoma, intrathoracic lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.02 – Nodular lymphocyte predominant Hodgkin lymphoma, intrathoracic lymph nodes
What it is
This code identifies nodular lymphocyte predominant Hodgkin lymphoma involving the intrathoracic lymph nodes. Use it when the record specifies this lymphoma subtype and the chest lymph nodes are the documented site.
Clinical signs
Clinical features vary; refer to documentation. Common findings include enlarged lymph nodes and symptoms related to mediastinal or hilar involvement, but diagnosis depends on pathology and site confirmation.
When to use this code
Use C81.02 when the provider documents nodular lymphocyte predominant Hodgkin lymphoma and names intrathoracic lymph nodes as the involved site. Apply it for confirmed primary or involved thoracic nodes when no more specific site code is documented. Check documentation if the record only states Hodgkin lymphoma without subtype or location.
Do not use for
Do not use this code for other Hodgkin lymphoma subtypes or for lymphoma outside the intrathoracic nodes. If the chart does not confirm the nodular lymphocyte predominant type, code only what is documented.
Coding tip
Match both the lymphoma subtype and the anatomic site exactly; if either is missing, review the pathology and provider note before assigning the code.
