ICD-10 Code C92.51 – Acute myelomonocytic leukemia, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C92.51 – Acute myelomonocytic leukemia, in remission
What it is
C92.51 identifies acute myelomonocytic leukemia that is documented as being in remission. Use it when the patient has a prior diagnosis of this AML subtype and the record states the disease is not currently active.
Clinical signs
Clinical features vary; refer to documentation. In remission, notes may describe no evidence of active leukemia, improving blood counts, or follow-up after treatment for acute myelomonocytic leukemia.
When to use this code
Use this code when the provider clearly documents acute myelomonocytic leukemia in remission, including complete or partial remission if that status is stated. It is appropriate for ongoing oncology follow-up, surveillance visits, or history review when the leukemia remains inactive. Check documentation if the remission status is unclear.
Do not use for
Do not use C92.51 for active acute myelomonocytic leukemia or for a history of leukemia without current remission wording. If the chart only says “status post leukemia” or gives another subtype, check documentation.
Coding tip
Code the remission status exactly as documented, and do not assume remission from treatment history alone.
