Many injured NC workers have questions when their doctor assigns a permanent partial disability rating. Many times injured workers are contacted by an adjuster working for their employer’s workers’ compensation insurance company urging them to accept payment of a rating or offering to settle their workers’ comp case. Some adjusters even tell the worker this is the only benefit available to them. Unfortunately, many workers accept payment of the injury rating in their NC workers’ comp case and later regret it. Permanent Partial Disability (PPD) ratings are sometimes called “injury ratings” or “impairment ratings.” It’s all the same thing — a great big caution sign.


There are a number of ways that disability is paid to an injured worker in a North Carolina Workers’ Compensation case.  Generally, in order to receive disability benefits an injured worker must be physically restricted from some or all work, working fewer hours, or working for reduced wages.  This is the case for Temporary Total Disability (TTD), Temporary Partial Disability (TPD), or Permanent Total Disability.

But injuries to certain parts of the body are presumed to be disabling under North Carolina workers’ compensation law. These body parts are listed in North Carolina General Statute § 97-31,  along with the number of weeks of presumed disability. Then an injured worker with an injury to one of these particular parts of the body reaches Maximum Medical Improvement, the authorized treating physician will generally assign a disability “rating” to that body part. This percentage rating is the doctor’s estimate of the percentage of permanent impairment to the affected body part.


It is usually simple to calculate how much an injury rating is worth. Just multiply the injury percentage rating by the employee’s compensation rate, and then multiply that result by the number of weeks assigned to the injured body part.

So, for example, an injured worker with a 10% disability rating to his or her back,  and a weekly compensation rate of $400, would calculate the value of the injury rating like this: 10% Rating x 300 Weeks (weeks assigned for a back) x $400 (employee’s compensation rate) = $12,000. In this case the injured worker’s injury rating is worth $12,000. So an an injury rating calculator in NC workers’ comp cases would look like this:

Percentage Rating Assigned X Number of Weeks Assigned to Body Part X Compensation Rate = PPD Rating.


Workers who have not returned to work at their pre-injury wage, have suffered a significant loss of wage-earning capacity, or are likely to need significant medical treatment in the future, should think long and hard before accepting the payment of a rating. There are several reasons why it can be a mistake for an injured worker to accept payment of their disability rating in a NC workers’ comp claim. In deciding whether to take the rating payment injured workers should keep in mind:

  • the payment of an injury rating starts the clock ticking on a two year deadline for for a change in condition under North Carolina General Statute 97-47.  If the employee does not file a notice with the North Carolina Industrial Commission that they have sustained a change in condition to the injured body part within two years of the payment of the disability rating, the employee may forever lose the right to claim additional disability benefits;
  • while accepting a rating does not immediately end the employee’s right to additional medical treatment, if  the employee accepts a rating, then goes two years without getting medical treatment paid for by the employer, or filing notice of a change in condition with the Industrial Commission, the employee runs the risk of losing both medical and wage replacement benefits forever;
  • accepting the payment of a rating terminates any ongoing payments of disability. In effect, the employee has “sold” their existing impairment to the workers’ compensation insurance company;
  • by accepting a payment on the PPD rating an injured worker may be giving up a more valuable wage replacement benefits, including Temporary Partial Disability payments for up to 500 weeks.

Accepting payment of an injury rating may make sense  if an injured worker has shown the ability to sustain full-time work, at the same or greater wage as prior to the injury, and if little additional medical treatment is anticipated in the future.


If accepting payment of a rating makes sense there are a few things to consider:

  • be sure the average weekly wage and compensation rate have been properly calculated. Even a small miscalculation of the employee’s average weekly wage can have a big effect on the value of the injury rating;
  • be sure the percentage impairment rating assigned by the authorized treating doctor reflects the true nature of the employee’s injury. The NC Industrial Commission has adopted a rating guide to assist doctors in determining ratings. An injured worker is entitled to get a second opinion on the rating with a physician he or she chooses;
  • be sure the employee is actually at Maximum Medical Improvement. MMI is the point at which the employee has reached the end of the healing period. It is not the point where a particular doctor has nothing else to offer.


Whether to take a workers’ comp rating in NC is a big decision. Sometimes adjusters suggest that payment of a rating is simply the next step in a workers’ comp claim. But there is nothing simple about accepting an injury rating in a North Carolina Workers’ Comp case.

If you are thinking about accepting a rating you should talk to a North Carolina workers’ comp attorney. This is especially true if you have not returned to full-duty work at full pay, have suffered a significant loss of wage earning capacity, or are looking at continuing medical treatment for your injury. A workers’ comp lawyer can help you consider your options and select the one that is best for you in the long run. You should also talk to a workers’ compensation attorney if you are considering settling your workers’ comp case in North Carolina.
