ICD-10 Code C95.00 – Acute leukemia of unspecified cell type not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C95.00 – Acute leukemia of unspecified cell type not having achieved remission
What it is
This code identifies an acute leukemia when the cell lineage is not specified and the disease has not achieved remission. Use it when the record confirms acute leukemia but does not name myeloid, lymphoid, or another subtype.
Clinical signs
Clinical features vary; refer to documentation. Common findings in acute leukemia include fatigue, infections, bruising, bleeding, and anemia-related symptoms, but the subtype must remain unspecified for this code.
When to use this code
Use this code when the provider documents acute leukemia without identifying the cell type and states that remission has not been achieved. It may also apply when the chart supports active disease, but the specific lineage is not recorded. Check documentation if remission status is unclear.
Do not use for
Do not use this code if the leukemia type is documented as myeloid, lymphoid, or another specific subtype. Do not assign it when the record shows remission or when documentation is incomplete enough that you must code a symptom or history instead.
Coding tip
Look for both the acute leukemia diagnosis and explicit non-remission status before assigning C95.00.
