Most workers fully recover from job injuries but some continue to have medical problems. Permanent disability (PD) is any lasting disability that results in a reduced earning capacity after maximum medical improvement is reached. If your injury or illness results in PD you are entitled to PD benefits, even if you are able to go back to work.

A doctor determines if your injury or illness caused PD. After your doctor decides your injury or illness has stabilized and no change is likely, PD is evaluated. At that time, your condition has become permanent and stationary (P&S). Your doctor might use the term maximal medical improvement (MMI) instead of P&S.

Once you are P&S or have reached MMI, your doctor will send a report to the claims administrator telling them you have PD. The doctor also determines if any of your disability was caused by something other than your work injury. For example, a previous injury or other condition. Assigning a percentage of your disability to factors other than your work injury is called apportionment.

 PD benefits are set by law. The claims administrator will determine how much to pay you based on three factors:

• Your disability rating (expressed as a percentage)
• Date of injury
• Your wages before you were injured.

PD benefits are normally paid when TD benefits end and your doctor indicates you have some permanent effects from your injury. The claims administrator must begin paying your PD payments within 14 days after TD ends. The claims administrator picks which day to pay you and will continue to make payments every two weeks until a reasonable estimate of your disability amount has been paid.

If you have not missed any work, PD payments are due when the claims administrator learns the injury has caused a permanent disability.
