ICD-10 Code C92.62 – Acute myeloid leukemia with 11q23-abnormality in relapse (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C92.62 – Acute myeloid leukemia with 11q23-abnormality in relapse
What it is
This code identifies acute myeloid leukemia (AML) with an 11q23 abnormality that has returned after remission. Use it when the record confirms both the specific genetic feature and relapse status.
Clinical signs
Clinical features vary; refer to documentation. AML relapse may be noted by recurrent blasts, marrow involvement, or return of leukemia-related findings after prior response, with the 11q23 abnormality documented in the chart.
When to use this code
Use this code when the provider documents relapsed AML and specifies an 11q23 abnormality, such as KMT2A rearrangement or an equivalent cytogenetic description. It is appropriate for encounters focused on active recurrent disease, not merely a past history of AML.
If the record says AML in remission, in remission status only, or gives no relapse detail, do not assign this code. Check documentation when the genetic subtype or relapse status is unclear.
Do not use for
Do not use it for AML without relapse, AML in remission, or unspecified AML subtypes. Do not infer the 11q23 abnormality from suspicion alone.
Coding tip
Confirm both relapse and the 11q23 abnormality in the same encounter note before assigning C92.62.
