Acute lymphoblastic leukemia, in remission

This code signifies a malignant neoplasm of lymphoid progenitor cells, specifically acute lymphoblastic leukemia (ALL), that is currently in a state of remission. Remission indicates that the signs and symptoms of the leukemia have significantly decreased or disappeared, often following successful treatment.

Apply this code when a patient with a documented history of acute lymphoblastic leukemia is currently in remission, as confirmed by bone marrow biopsy, peripheral blood counts, and other relevant laboratory markers. This code is appropriate for ongoing surveillance and follow-up care of patients who have achieved remission.

• Ensure documentation explicitly states "in remission" for acute lymphoblastic leukemia; avoid using for active disease or relapse.
• Do not confuse with codes for ALL in relapse or ALL not specified as in remission or relapse.
• Sequence this code as a primary diagnosis when the reason for the encounter is related to the patient's remission status or follow-up care for the ALL.
