Personal history of congenital malform of heart and circ sys

This code indicates a patient's past medical history of a congenital heart or circulatory system defect that has been corrected or is no longer actively treated. It signifies that the patient previously had such a condition, but it is not currently an active problem requiring ongoing management for the malformation itself.

Use this code for follow-up encounters of patients who have undergone successful surgical repair or other definitive correction of a congenital heart defect, such as a ventricular septal defect or coarctation of the aorta. It is appropriate when the patient is no longer receiving active treatment for the congenital malformation, but the history remains relevant to their overall health status.

• Do not use this code if the congenital malformation is still active, uncorrected, or requires ongoing treatment.
• Always sequence this code as a secondary diagnosis, as it represents a historical condition.
• Consider additional codes for any residual effects or complications directly related to the past congenital malformation.
