A history of an MI uses code I25.2, which describes an old myocardial infarct. This code is used only if the patient has no symptoms and only if the old MI was diagnosed by means of an electrocardiogram. If an MI is specified as "old" or "healed" without any current or presenting symptoms, it should be coded using category I21. If the patient is symptomatic, code the underlying condition or symptoms only if the underlying condition is not known, code I21.3.
