ICD-10 Code C82.5 – Diffuse follicle center lymphoma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.5 – Diffuse follicle center lymphoma
What it is
C82.5 identifies diffuse follicle center lymphoma, a type of non-Hodgkin lymphoma arising from germinal center B cells. Use it when documentation specifies this exact histologic subtype.
Clinical signs
Clinical features vary; refer to documentation. Typical lymphoma findings may include persistent lymphadenopathy, systemic “B” symptoms, or biopsy-confirmed diffuse follicle center lymphoma.
When to use this code
Use C82.5 when the provider documents diffuse follicle center lymphoma as the diagnosis, usually supported by pathology or oncology assessment. It is appropriate for confirmed cases being evaluated, staged, or followed in ongoing care. Check documentation if the record only says follicular lymphoma or another subtype.
Do not use for
Do not use this code for unspecified follicular lymphoma, other non-Hodgkin lymphomas, or benign lymphoid hyperplasia. If the subtype is not clearly stated, check documentation.
Coding tip
Code the documented lymphoma subtype exactly; histology wording in pathology reports often determines the correct ICD-10-CM selection.
