ICD-10 Code C81.95 – Hodgkin lymphoma, unspecified, lymph nodes of inguinal region and lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C81.95 – Hodgkin lymphoma, unspecified, lymph nodes of inguinal region and lower limb
What it is
C81.95 identifies Hodgkin lymphoma when the site is the inguinal region or lower limb lymph nodes and the subtype is not specified. Use it for documented Hodgkin lymphoma involving those nodes when the record does not name a more specific histology.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include enlarged inguinal nodes, other peripheral lymphadenopathy, or systemic “B symptoms” such as fever, night sweats, or weight loss, but you should code only what is documented.
When to use this code
Use this code when the provider documents Hodgkin lymphoma affecting lymph nodes of the groin or lower limb and does not specify a more detailed subtype. It also fits when pathology or imaging supports nodal disease in this region, but the record remains nonspecific. If the site or histology is clarified later, update the code accordingly.
Do not use for
Do not use C81.95 for non-Hodgkin lymphoma, leukemia, or nonspecific lymph node enlargement without a lymphoma diagnosis. Do not assign it when the record identifies a different Hodgkin subtype or a different nodal region.
Coding tip
Check the pathology and provider assessment for both the lymphoma type and the exact nodal site before selecting this code.
