Official Coding Guidelines

I69 sequelae vs Z86.73 personal history; deficits required

3) Codes from category I69 and Personal history of transient ischemic attack (TIA) and cerebral infarction (Z86.73) Codes from category I69 should not be assigned if the patient does not have neurologic deficits. See Section I.C.21.4. History (of) for use of personal history codes

Used with any code in range A00.0-T88.9, Z00-Z99

1) Used with any code in the range of A00.0-T88.9, Z00-Z99 An external cause code may be used with any code in the range of A00.0-T88.9, Z00-Z99, classification that represents a health condition due to an external cause. Though they are most applicable to injuries, they are also valid for use with such things as infections or diseases due to an external source, and other health conditions, such as a heart attack that occurs during strenuous physical activity.
