ICD-10 Code C95.11 – Chronic leukemia of unspecified cell type, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C95.11 – Chronic leukemia of unspecified cell type, in remission
What it is
C95.11 identifies a chronic leukemia when the specific cell type is not documented and the disease is in remission. Use it when the record confirms a chronic leukemia history but does not name the lineage.
Clinical signs
Clinical features vary; refer to documentation. Remission usually means the leukemia is not showing active disease, though the patient may still have a documented history of ongoing hematology follow-up or surveillance.
When to use this code
Use this code when the provider states chronic leukemia, unspecified cell type, and documents remission. It fits follow-up visits, surveillance encounters, or problem lists when the condition remains clinically relevant but inactive. Check documentation if the note does not clearly say remission.
Do not use for
Do not use C95.11 if the leukemia is active, relapsed, or in partial remission only. Do not assign it when the cell type is specified and a more precise code is available.
Coding tip
Confirm both “chronic” and “in remission” in the provider note before coding C95.11.
