A nonscheduled or unscheduled permanent disability is any compensable disability not listed in the workers comp schedules listed in Wis. Stats. Sec. 102.52 to 102.56. Mostly this involves a disability to the torso or head (but not involving sight or hearing loss). So, a permanent disability involving the low back, neck, abdomen, mental or psychological processes are unscheduled.
At the end of healing, TTD benefits stop. If there is a permanent disability, then PPD or permanent partial disability benefits in Wisconsin workers compensation law are payable. Permanent disability benefits in workers compensation are designed to compensate an injured worker for future loss of earnings. PPD benefits are based on a the percentage of disability assigned by a doctor, and in serious unscheduled cases, a vocational expert. PPD benefits accrue weekly after temporary disability benefits stop and are based on the average weekly wage determined on the date of injury. The permanent partial disability (PPD) benefit rate is two-thirds of the employee's average weekly wage, but not more than the statutory maximum PPD rate on the date of injury.
