ICD-10 Code C82.95 – Follicular lymphoma, unspecified, lymph nodes of inguinal region and lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.95 – Follicular lymphoma, unspecified, lymph nodes of inguinal region and lower limb
What it is
C82.95 identifies follicular lymphoma when the site is the inguinal region or lower limb lymph nodes and the subtype is not further specified. Use it for a documented lymphoid malignancy in those nodes.
Clinical signs
Clinical features vary; refer to documentation. Follicular lymphoma commonly presents with enlarged, usually painless lymph nodes, and diagnosis is based on pathology and clinical correlation.
When to use this code
Use this code when the record states follicular lymphoma and specifies involvement of inguinal or lower-limb lymph nodes, but does not name a more specific follicular lymphoma subtype. It also fits when the provider documents the site as the primary coded location for this lymphoma. Check documentation if multiple nodal regions are involved.
Do not use for
Do not use it when the lymphoma is in a different lymph node region or when the record identifies another non-follicular lymphoma type. If the pathology report gives a more specific follicular lymphoma code, use that instead.
Coding tip
Verify both the lymphoma type and nodal site in the pathology or assessment note before assigning C82.95.
