You usually see this in a claim closure letter, a doctor's report, or a benefits notice saying you were awarded a certain percentage or number of degrees for lost function. What it means is simple: the injury is not expected to fully heal, you still have lasting damage, but you are not considered totally unable to work. The loss might be in movement, strength, sensation, hearing, vision, or some other body function. "Permanent" means it is expected to stay. "Partial" means it limits you, but does not wipe out all ability to work.

In real life, this is where fights over money start. A workers' compensation insurer may accept that you were hurt and still try to minimize how much permanent damage the injury left behind. The rating can affect how much compensation you receive after your condition becomes medically stationary. That usually turns on medical findings, work restrictions, and whether the injury changed your ability to do the job you held at the time of injury.

In Oregon, permanent partial disability is commonly awarded in a Notice of Closure after an accepted claim. The rating process is governed by Oregon workers' compensation law, including ORS Chapter 656 and the Director's standards for disability ratings. If the award is too low, a worker may challenge it through reconsideration and, if needed, a hearing before the Workers' Compensation Board. This is not a label. It is a number that directly affects what gets paid.
