ICD-10 Code C83.0A – Small cell B-cell lymphoma, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C83.0A – Small cell B-cell lymphoma, in remission
What it is
This code identifies a history of small cell B-cell lymphoma that is currently in remission. Use it when the lymphoma is no longer active, but the patient still has a documented diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Remission usually means there is no evidence of active lymphoma on current evaluation, although prior disease remains part of the record.
When to use this code
Use this code when the provider clearly documents small cell B-cell lymphoma as being in remission. It is appropriate for follow-up visits, survivorship care, or ongoing monitoring after treatment. Do not substitute it for active disease or uncertain status; check documentation.
Do not use for
Do not use this code if the lymphoma is active, recurrent, or only suspected. It is also not the right choice when the record says “history of” without documenting remission.
Coding tip
Look for the exact phrase “in remission” in the assessment or problem list before assigning C83.0A.
