ICD-10 Code C85.80 – Other specified types of non-Hodgkin lymphoma, unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C85.80 – Other specified types of non-Hodgkin lymphoma, unspecified site
What it is
This code identifies a non-Hodgkin lymphoma that is documented as a specific “other specified” type, but the site is not stated. Use it when the provider names the lymphoma type and no more precise site is available.
Clinical signs
Clinical features vary; refer to documentation. Non-Hodgkin lymphoma often presents with enlarged lymph nodes, systemic “B” symptoms, or extranodal involvement, but the exact findings depend on the subtype.
When to use this code
Use this code when the record clearly states an other specified non-Hodgkin lymphoma and does not identify a more specific anatomic site. It may also fit when the site is documented as unknown, unspecified, or not applicable. If the pathology or clinician note gives a more exact lymphoma type or site, choose the more specific code.
Do not use for
Do not use it for Hodgkin lymphoma, unspecified non-Hodgkin lymphoma, or a lymphoma with a documented specific site code. Check documentation if the subtype is not clearly stated.
Coding tip
Code from the most specific lymphoma description available, and query when the site or subtype is missing.
