ICD-10 Code C82.9A – Follicular lymphoma, unspecified, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.9A – Follicular lymphoma, unspecified, in remission
What it is
This code identifies follicular lymphoma when the type is not further specified and the patient is documented as being in remission. Use it for a history of this lymphoma with current remission status, not active disease.
Clinical signs
Clinical features vary; refer to documentation. Follicular lymphoma is typically a non-Hodgkin lymphoma that may present with painless lymph node enlargement, but remission means current signs of active disease are not documented.
When to use this code
Use this code when the record states follicular lymphoma, unspecified, and clearly documents remission. It fits follow-up visits, surveillance encounters, or problem lists when the condition remains relevant but is not active. Check documentation if the remission status is unclear.
Do not use for
Do not use it for active follicular lymphoma, for a different lymphoma subtype, or when the chart only says “history of lymphoma” without specifying follicular lymphoma. Check documentation if the site or behavior is missing.
Coding tip
Confirm both the lymphoma type and remission status in the note before assigning C82.9A.
