If the patient has an injury, say fx or sprain, but they state no known injury, What external cause code would be appropriate for this if the cause of injury is not known? The guidelines state not to use Y93.9 Unspecified activity, if the activity is not known. The only thing close that I can find is X58.XXXA, Exposure to other specified factors, Accident NOS/Exposure NOS.
