ICD-10 Code C81.41 – Lymphocyte-rich Hodgkin lymphoma, lymph nodes of head, face, and neck (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.41 – Lymphocyte-rich Hodgkin lymphoma, lymph nodes of head, face, and neck
What it is
This code identifies a specific subtype of Hodgkin lymphoma with lymphocyte-rich histology, located in lymph nodes of the head, face, and neck. Use it when documentation names both the subtype and the anatomic site.
Clinical signs
Clinical features vary; refer to documentation. Hodgkin lymphoma commonly presents with enlarged lymph nodes, and this code applies only when the record confirms a lymphocyte-rich pattern in the head, face, or neck nodes.
When to use this code
Use C81.41 when the provider documents lymphocyte-rich Hodgkin lymphoma affecting cervical, facial, or other head and neck lymph nodes. It is appropriate for confirmed primary or site-specific documentation, including pathology-supported diagnoses. Check documentation if the histology or nodal location is unclear.
Do not use for
Do not use this code for other Hodgkin lymphoma subtypes or for unspecified nodal sites. It is also incorrect if the chart only mentions lymphoma without confirming lymphocyte-rich Hodgkin lymphoma in the head, face, or neck.
Coding tip
Code from the most specific pathology and site documentation available; if either element is missing, check documentation before assigning C81.41.
