ICD-10 Code C95.01 – Acute leukemia of unspecified cell type, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C95.01 – Acute leukemia of unspecified cell type, in remission
What it is
C95.01 identifies a history of acute leukemia of unspecified cell type that is currently in remission. You use it when the record states the leukemia is not active, but the specific cell lineage is not documented.
Clinical signs
Clinical features vary; refer to documentation. In remission, the chart should indicate no active leukemic disease, often with follow-up for prior acute leukemia and ongoing hematology monitoring.
When to use this code
Use this code when the provider documents acute leukemia, unspecified cell type, and clearly states remission. It fits follow-up visits, surveillance, or ongoing management after treatment when the disease is not currently active. Do not infer remission without explicit documentation.
Do not use for
Do not use this code for active acute leukemia, relapse, or persistent disease. If the leukemia type is specified elsewhere in the record, code the documented specific type instead; check documentation.
Coding tip
Confirm both the leukemia status and the “unspecified cell type” wording before assigning C95.01.
