Lymphoid leukemia, unspecified, in remission

This code signifies a diagnosis of lymphoid leukemia where the specific type (e.g., acute, chronic, B-cell, T-cell) is not documented, and the patient is currently in a state of remission. Remission indicates a significant reduction or absence of disease signs and symptoms, but not necessarily a cure.

Apply this code when documentation clearly states "lymphoid leukemia, unspecified" and explicitly indicates "in remission." This is appropriate for follow-up encounters or surveillance when the patient is no longer undergoing active treatment for the leukemia but is being monitored for recurrence.

• Do not use this code if the specific type of lymphoid leukemia (e.g., acute lymphoblastic leukemia) is known; instead, code to the specific type with the appropriate remission subclassification.
• Ensure documentation explicitly states "in remission" for this code to be valid; "history of" or "status post treatment" alone are insufficient.
• Sequence this code as a secondary diagnosis if the patient is being seen for a complication or sequela of the leukemia or its treatment.
