If your scheduled exam date or time does not work with some other life event, immediately call the number provided and try to reschedule. Unless it is an emergency situation, try not to reschedule the exam the day before or on the day of the exam. Not responding to a phone or letter request for scheduling an exam or missing the exam could cause VA to delay its decision on your claim. Not showing up to your exam takes up an appointment time another Veteran could have used, and also could cause your claim to be rated “as-is” based only on the information in your application. Most facilities try to meet your requests (if possible) if you have a good reason for rescheduling your time and you give enough notice.
