ICD-10 Code C92.92 – Myeloid leukemia, unspecified in relapse (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C92.92 – Myeloid leukemia, unspecified in relapse
What it is
C92.92 identifies a myeloid leukemia that has returned after a period of remission, but the specific subtype is not documented. Use it when the record confirms relapse and does not name a more exact myeloid leukemia.
Clinical signs
Clinical features vary; refer to documentation. Relapse is usually supported by evidence that leukemia has reappeared after remission, such as bone marrow or peripheral blood findings and oncology assessment.
When to use this code
Use this code when the provider documents recurrent myeloid leukemia and does not specify a more precise type. It also fits follow-up notes that clearly state the disease is in relapse. If the chart names a specific myeloid leukemia subtype, code that diagnosis instead.
Do not use for
Do not use it for myeloid leukemia in remission, newly diagnosed disease, or unspecified leukemia without relapse. Check documentation if the recurrence status or leukemia type is unclear.
Coding tip
Code relapse only when the record explicitly states recurrence after remission; otherwise, query the provider.
