Acute myeloid leukemia w multilineage dysplasia, in relapse

This code signifies a recurrence of acute myeloid leukemia (AML) that initially presented with multilineage dysplasia. This specific subtype of AML involves abnormal development in at least two myeloid cell lines (e.g., granulocytic, erythroid, megakaryocytic) and has now re-emerged after a period of remission.

Use this code when documentation clearly indicates a diagnosis of AML with multilineage dysplasia and the patient is currently experiencing a relapse of the disease. This applies to situations where the patient previously achieved remission but now shows signs of active leukemia. Supporting documentation would include pathology reports confirming AML with multilineage dysplasia and physician notes indicating a relapse.

• Ensure documentation explicitly states "relapse" or "recurrent" in the context of AML with multilineage dysplasia.
• Do not confuse with initial diagnosis or AML in remission; specific codes exist for those scenarios.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
