If your treating physician on your accepted workers' compensation claim in Nevada reports to your claims adjuster that you may have a ratable impairment, you should be scheduled for an impairment evaluation 30 days later. This evaluation, also called a rating, will be done by one of the 138 doctors and chiropractors who have been tested and authorized by the state agency, DIR, to perform ratings. The purpose of the rating evaluation is to determine your percentage of impairment so that a permanent partial disability award can be offered. (The additional two factors that determine a PPD award in Nevada are the injured worker's average monthly wage at the time of the injury, and the injured worker's age when he or she has the evaluation.)

As of March 1, 2012, the Medical Unit at DIR has138 physicians and chiropractors on a rotating list. When a claims adjuster requests a rating, the Medical Unit secretary must assign the next one from the rotating list. If the injury is to a muskuloskeletal part, such as the shoulder or neck, a chiropractor may be assigned to do the rating. Some of the chiropractors on the rotating list are excellent rating doctors- fair, knowledgeable about the Guides and anatomy, and they correctly explain their findings and conclusions.
