ICD-10 Code C85.95 – Non-Hodgkin lymphoma, unspecified, lymph nodes of inguinal region and lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C85.95 – Non-Hodgkin lymphoma, unspecified, lymph nodes of inguinal region and lower limb
What it is
C85.95 identifies non-Hodgkin lymphoma when the site is the inguinal region or lower limb lymph nodes and the subtype is not specified. Use it when the record names lymphoma in these nodes but does not give a more precise histology.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include enlarged, firm, or painless lymph nodes in the groin or nearby leg drainage areas, sometimes with systemic “B” symptoms such as fever, night sweats, or weight loss.
When to use this code
Use this code when the provider documents non-Hodgkin lymphoma involving inguinal region or lower limb lymph nodes and does not specify the lymphoma type. It also fits when pathology or imaging confirms nodal involvement at that site, but the subtype remains unspecified. If a more specific lymphoma diagnosis is documented, code that instead.
Do not use for
Do not use it for Hodgkin lymphoma, metastatic cancer to lymph nodes, or lymphoma in a different nodal region. Check documentation if the record names a specific non-Hodgkin subtype or a different primary site.
Coding tip
Confirm both the lymphoma type and the nodal location before assigning C85.95.
