ICD-10 Code C82.2A – Follicular lymphoma grade III, unspecified, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.2A – Follicular lymphoma grade III, unspecified, in remission
What it is
This code identifies a history of follicular lymphoma grade III, unspecified subtype, that is currently in remission. Use it when the record states the lymphoma is no longer active but still requires follow-up.
Clinical signs
Clinical features vary; refer to documentation. Typical follicular lymphoma findings may include prior lymph node enlargement, fatigue, or B symptoms, but remission means active disease is not currently documented.
When to use this code
Use this code when the provider documents follicular lymphoma grade III, unspecified, and clearly states it is in remission. It is appropriate for follow-up visits, surveillance, or ongoing oncology review after treatment response. If the record does not confirm remission, check documentation before coding.
Do not use for
Do not use this code for active follicular lymphoma, relapsed disease, or a different lymphoma grade or subtype. If the chart only says “history of lymphoma” without remission status, check documentation.
Coding tip
Confirm both the grade and remission status in the provider note before assigning C82.2A.
