ICD-10 Code C82.0A – Follicular lymphoma grade I, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.0A – Follicular lymphoma grade I, in remission
What it is
C82.0A identifies a history of follicular lymphoma, grade I, that is currently in remission. Use it when the lymphoma is no longer active but remains a documented diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Follicular lymphoma is typically a slow-growing non-Hodgkin lymphoma, often noted by lymph node enlargement, but remission means active disease is not currently present.
When to use this code
Use this code when the provider documents grade I follicular lymphoma and states that the patient is in remission. It is appropriate for follow-up visits, surveillance, or ongoing oncology records after treatment response. Check documentation if remission status is unclear.
Do not use for
Do not use this code for active follicular lymphoma, unspecified grade, or cases where remission is not documented. If the record only says “history of lymphoma” without remission status, check documentation.
Coding tip
Code only when the record clearly links grade I follicular lymphoma with remission; otherwise, query the provider.
