ICD-10 Code C81.01 – Nodular lymphocyte predominant Hodgkin lymphoma, lymph nodes of head, face, and neck (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.01 – Nodular lymphocyte predominant Hodgkin lymphoma, lymph nodes of head, face, and neck
What it is
This code identifies nodular lymphocyte predominant Hodgkin lymphoma involving lymph nodes in the head, face, or neck. Use it when documentation specifies this lymphoma subtype and the anatomic site.
Clinical signs
Clinical features vary; refer to documentation. Commonly, patients present with enlarged lymph nodes in the neck or nearby regions, and diagnosis is confirmed by pathology consistent with nodular lymphocyte predominant Hodgkin lymphoma.
When to use this code
Use this code when the record clearly states nodular lymphocyte predominant Hodgkin lymphoma and identifies lymph nodes of the head, face, or neck as the involved site. It is appropriate for initial diagnosis, follow-up care, or ongoing management when that site remains documented. Check documentation if the location is broader or unspecified.
Do not use for
Do not use this code if the lymphoma subtype is not specified or if the involved lymph nodes are in another body region. Avoid it when the chart only says Hodgkin lymphoma without confirming nodular lymphocyte predominant type.
Coding tip
Match both the lymphoma subtype and the exact nodal location in the pathology or oncology note before assigning C81.01.
