Personal history of diseases of blood and blood-forming organs

This code indicates a patient's past medical history of conditions affecting the blood, bone marrow, spleen, or lymphatic system. It signifies that while the patient previously had such a disease, they are no longer actively experiencing it and are not receiving treatment for it. This history can be relevant for risk assessment or future treatment planning.

This code is appropriate when documenting a resolved diagnosis of a hematologic or lymphatic disorder, such as a past anemia, leukemia in remission, or a history of splenectomy due to a blood-related condition. It should be used when the patient is currently asymptomatic and the condition is no longer active.

• Do not use this code for current, active blood disorders; use specific diagnosis codes for those.
• Ensure documentation clearly states the condition is resolved or in remission.
• This code is often used as a secondary diagnosis to provide a comprehensive patient history.
