ICD-10 Code C92.02 – Acute myeloblastic leukemia, in relapse (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C92.02 – Acute myeloblastic leukemia, in relapse
What it is
C92.02 identifies acute myeloblastic leukemia that has returned after a documented remission. Use it when the record clearly states relapse or recurrent disease, not the initial diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe recurrent blasts, worsening anemia, infection, bruising, or bleeding after prior response to therapy.
When to use this code
Use this code when the provider documents acute myeloblastic leukemia as relapsed, recurrent, or in second remission with active disease again. It may also apply when oncology notes confirm return of AML after prior treatment response. Check documentation for disease status and history.
Do not use for
Do not use C92.02 for newly diagnosed AML, remission without active relapse, or unspecified leukemia status. If the chart does not clearly state relapse, check documentation.
Coding tip
Look for explicit terms such as “relapse,” “recurrent,” or “returned after remission” before assigning this code.
