ICD-10 Code C92.A2 – Acute myeloid leukemia with multilineage dysplasia, in relapse (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C92.A2 – Acute myeloid leukemia with multilineage dysplasia, in relapse
What it is
This code identifies acute myeloid leukemia with multilineage dysplasia that has returned after prior remission. It signals an AML subtype with abnormal development in more than one blood cell line.
Clinical signs
Patients typically show findings of relapsed AML, such as worsening anemia, infection risk, bruising, or bleeding. Clinical features vary; refer to documentation for the relapse status and multilineage dysplasia subtype.
When to use this code
Use C92.A2 when the provider documents acute myeloid leukemia with multilineage dysplasia and states that the disease is in relapse. Apply it when the record clearly supports both the AML subtype and recurrent disease after remission.
If the note only says AML relapse without specifying multilineage dysplasia, check documentation. Do not assume this code from a generic AML recurrence entry.
Do not use for
Do not use this code for AML not in relapse, or for other myeloid neoplasms without multilineage dysplasia. Check documentation if the subtype or recurrence status is unclear.
Coding tip
Confirm both elements in the chart: multilineage dysplasia and relapse status, before assigning C92.A2.
