ICD-10 Code C82.54 – Diffuse follicle center lymphoma, lymph nodes of axilla and upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.54 – Diffuse follicle center lymphoma, lymph nodes of axilla and upper limb
What it is
This code identifies diffuse follicle center lymphoma involving lymph nodes in the axilla or upper limb. Use it when the record specifies this lymphoma subtype and location.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include enlarged lymph nodes in the axilla or upper limb region, with diagnosis confirmed by pathology and clinical evaluation.
When to use this code
Use C82.54 when the provider documents diffuse follicle center lymphoma and clearly links it to lymph nodes of the axilla or upper limb. It is appropriate for confirmed malignancy coding when site and histology are both specified. Check documentation if the anatomic site is unclear or if another lymphoma subtype is recorded.
Do not use for
Do not use this code for unspecified lymphoma, other follicular lymphomas without this exact site, or benign lymph node enlargement. If the record does not confirm diffuse follicle center lymphoma, choose a more accurate code.
Coding tip
Verify both the lymphoma type and the exact nodal location before assigning C82.54.
