ICD-10 Code C81.71 – Other Hodgkin lymphoma, lymph nodes of head, face, and neck (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.71 – Other Hodgkin lymphoma, lymph nodes of head, face, and neck
What it is
This code identifies Hodgkin lymphoma classified as “other” and documented as involving lymph nodes in the head, face, or neck. Use it when the record specifies this anatomic site and does not name a more specific Hodgkin lymphoma type.
Clinical signs
Typical findings include painless enlarged cervical or other head-and-neck lymph nodes, sometimes with systemic “B” symptoms such as fever, night sweats, or weight loss. Clinical features vary; refer to documentation.
When to use this code
Use C81.71 when the provider documents other Hodgkin lymphoma affecting lymph nodes of the head, face, or neck. Apply it when pathology, oncology notes, or discharge summaries clearly support the diagnosis and site. If the site or subtype is unclear, check documentation before coding.
Do not use for
Do not use this code for non-Hodgkin lymphoma, unspecified Hodgkin lymphoma, or Hodgkin lymphoma involving a different lymph node region. Check documentation if the record does not clearly identify the head, face, or neck nodes.
Coding tip
Confirm both the lymphoma type and the exact lymph node region in the final diagnosis before assigning C81.71.
