ICD-10 Code C95.10 – Chronic leukemia of unspecified cell type not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C95.10 – Chronic leukemia of unspecified cell type not having achieved remission
What it is
This code identifies chronic leukemia when the cell type is not specified and the disease has not achieved remission. Use it only when the record clearly states chronic leukemia without a more exact subtype.
Clinical signs
Clinical features vary; refer to documentation. Common findings in chronic leukemia may include persistent abnormal blood counts, fatigue, enlarged spleen or lymph nodes, and other signs of marrow involvement.
When to use this code
Use C95.10 when the provider documents chronic leukemia, unspecified cell type, and indicates the condition is active or not in remission. It is appropriate for encounters focused on ongoing disease evaluation, monitoring, or complications. Check documentation if the chart does not clearly state remission status.
Do not use for
Do not use this code if the leukemia type is specified, such as lymphoid or myeloid, or if the record states remission. Check documentation before assigning a more specific leukemia code.
Coding tip
Confirm both the chronic leukemia designation and non-remission status in the provider note before coding.
