ICD-10 Code C82.5A – Diffuse follicle center lymphoma, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.5A – Diffuse follicle center lymphoma, in remission
What it is
This code identifies diffuse follicle center lymphoma that is currently in remission. Use it when the diagnosis remains active in the record, but the disease is documented as no longer active.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe diffuse follicle center lymphoma as a B-cell non-Hodgkin lymphoma, often confirmed by pathology and staging information.
When to use this code
Use this code when the provider documents diffuse follicle center lymphoma and clearly states it is in remission. It is appropriate for follow-up visits, surveillance, or ongoing oncology care when the malignancy is not currently active. Check documentation if remission status is unclear.
Do not use for
Do not use this code if the lymphoma is active, suspected, or history only without current remission wording. Do not guess remission status from treatment history alone.
Coding tip
Look for explicit provider language such as “in remission” or “no evidence of disease” before assigning C82.5A.
