ICD-10 Code C83.5A – Lymphoblastic (diffuse) lymphoma, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C83.5A – Lymphoblastic (diffuse) lymphoma, in remission
What it is
This code identifies a history of lymphoblastic lymphoma that is currently in remission. Use it when the disease is not active, but the diagnosis remains clinically relevant.
Clinical signs
Clinical features vary; refer to documentation. Remission usually means there is no evidence of active lymphoma on current evaluation, although prior disease may still affect follow-up care.
When to use this code
Use this code when the provider documents lymphoblastic lymphoma as being in remission, inactive, or with no current evidence of disease. It is appropriate for follow-up visits, surveillance, and problem lists when the condition remains part of the patient’s record.
Do not assume remission unless the note clearly supports it. If the record only states a past history of lymphoma without remission status, check documentation before coding.
Do not use for
Do not use this code for active lymphoblastic lymphoma or for unspecified lymphoma types. Also avoid it when the chart does not clearly document remission status.
Coding tip
Code the remission status exactly as documented; if it is unclear, query the provider.
