Other myeloid leukemia, in relapse

This code signifies a recurrence or worsening of a myeloid leukemia that is not otherwise specified as acute, chronic, or a specific subtype like myelodysplastic syndrome-related or therapy-related. It indicates that the patient's cancer, previously in remission, has returned or progressed.

Use this code when documentation explicitly states "other myeloid leukemia, in relapse" or "recurrent other myeloid leukemia." This applies to patients whose myeloid leukemia, not fitting other specific ICD-10-CM categories, has shown signs of active disease after a period of remission. Supporting documentation should include physician notes confirming the diagnosis and the relapsed status.

• Ensure the documentation clearly specifies "relapse" and not just "active disease" if the patient was never in remission.
• Do not use this code for acute myeloid leukemia (AML) or chronic myeloid leukemia (CML) in relapse; use the specific codes for those conditions.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, followed by any associated complications or treatments.
