The VA appeal process often drags for several years at a time. The veteran's health can fluctuatewhile a claim is pending during this time. The individual may get medical treatment related to the illness and go through a period of recovery when he or she is incapacitated. After the treatment the veteran is restored to their prior health or is left with residuals related to the illness or the treatment. In this case the veteran would be entitled to different ratings for different periods of time.These different ratings are called "staged ratings." The medical and other evidence show symptoms that determine the rating for each period of time.
