ICD-10 Code C85.9A – Non-Hodgkin lymphoma, unspecified, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C85.9A – Non-Hodgkin lymphoma, unspecified, in remission
What it is
This code identifies a history of non-Hodgkin lymphoma that is currently in remission, but the specific subtype is not documented. Use it when the record confirms remission and does not name a more specific lymphoma type.
Clinical signs
Clinical features vary; refer to documentation. You may see prior evidence of lymphoma with current remission status noted in oncology follow-up, survivorship records, or problem lists.
When to use this code
Use this code when the clinician documents non-Hodgkin lymphoma in remission and does not specify the histologic subtype. It is appropriate for follow-up encounters, surveillance visits, or ongoing cancer history documentation. If the subtype is later identified, code that more specific diagnosis instead.
Do not use for
Do not use this code for active, recurrent, or relapsed lymphoma. Do not use it when the documentation names a specific non-Hodgkin lymphoma subtype or when remission is not clearly stated.
Coding tip
Check the latest oncology note for exact wording; remission status and lymphoma type must both be documented to support accurate code selection.
