Personal history of leukemia

This code indicates that a patient has a documented history of leukemia but is currently free of the disease and not undergoing active treatment. It signifies a past diagnosis that no longer requires active management, distinguishing it from current or recurrent disease.

Assign this code when a patient has completed treatment for leukemia and is considered to be in full remission or cured, and the condition is no longer present. It is appropriate for follow-up encounters where the primary focus is on monitoring for recurrence or managing long-term effects of past treatment.

• Do not use this code if the patient is currently undergoing treatment for leukemia or has active disease.
• Refer to the Excludes1 note; if the leukemia is in remission, use the appropriate C91-C95 code with the 5th character '1'.
• This code is typically used as a secondary diagnosis to provide a comprehensive medical history.
