Acute promyelocytic leukemia, in remission

This code signifies a diagnosis of acute promyelocytic leukemia (APL) that is currently in a state of remission. APL is a subtype of acute myeloid leukemia characterized by a specific chromosomal translocation, and "in remission" indicates that the signs and symptoms of the disease have significantly decreased or disappeared following treatment.

This code is appropriate for patients with a documented history of APL who are currently in remission, as confirmed by bone marrow biopsy, molecular testing, and/or peripheral blood counts. It should be used when the patient is receiving ongoing monitoring or maintenance therapy for their APL, or when their remission status is being reported.

• Always confirm "in remission" status with physician documentation, such as bone marrow reports or progress notes.
• Do not use this code if the patient is actively undergoing initial treatment for APL or is in relapse.
• Sequence this code as a secondary diagnosis if the patient is being treated for a complication of their APL or its treatment.
