Acute erythroid leukemia, not having achieved remission

This code signifies a diagnosis of acute erythroid leukemia (AEL), a rare and aggressive subtype of acute myeloid leukemia (AML) characterized by the proliferation of immature red blood cell precursors. It specifically indicates that the patient has not yet achieved remission following treatment or is still in the active phase of the disease.

Apply this code when documentation clearly states a diagnosis of acute erythroid leukemia and explicitly indicates that the patient is not in remission. This is typically used for initial diagnoses, during active treatment phases, or when remission has not been achieved after a course of therapy.

• Ensure documentation specifies "acute erythroid leukemia" and not another AML subtype.
• Verify that the patient's current status is "not in remission"; if remission is achieved, a different code would be appropriate.
• Sequence this code as the primary diagnosis when it is the reason for the encounter.
