In Illinois, permanent partial disability (PPD) benefits are calculated using Schedule injuries & wage differential — administered by the Illinois Workers' Compensation Commission — with a maximum weekly benefit of $1,897.
Permanent partial disability (PPD) in Illinois is awarded after you reach Maximum Medical Improvement (MMI) and your treating physician assigns a permanent impairment rating. Illinois uses schedule injuries & wage differential to calculate PPD benefits. The impairment rating is expressed as a percentage of the whole body or as a specific body-part award, and multiplied by a dollar value set by state law to arrive at your PPD benefit.
The three main permanent disability systems in the U.S. are: (1) Impairment-based — your impairment percentage is multiplied by a fixed value per percent; (2) Scheduled loss — each body part has a maximum number of benefit weeks, and you receive a fraction based on impairment; (3) Wage-loss — benefits are based on the actual difference between pre- and post-injury earning capacity. Illinois uses the schedule injuries & wage differential method, administered by the Illinois Workers' Compensation Commission.
Independent Medical Examinations (IMEs) play a central role in permanent disability determinations. Both you and the insurer have the right to request an IME if you disagree with the treating physician's impairment rating. If you receive a PPD rating you believe is too low, you have the right to challenge it through the Illinois Workers' Compensation Commission within 30 days.

In Illinois, schedule injuries & wage differential is used to rate PPD. After reaching Maximum Medical Improvement, your treating physician assigns an impairment rating that is converted to a dollar amount or weeks of benefits based on Illinois's PPD schedule and your weekly benefit rate of 67%.
Yes. Permanent partial disability (PPD) benefits are awarded for permanent loss of function — they are not conditioned on current employment status. If you receive a PPD settlement and later return to full-duty work, you keep your PPD award.
The maximum PPD payout in Illinois depends on your impairment rating, your pre-injury wages, and the state's PPD schedule. With a maximum weekly benefit of $1,897, a high impairment rating and serious injury can result in a substantial PPD award, potentially hundreds of thousands of dollars for severe whole-body impairment.
An Independent Medical Examination (IME) is a medical evaluation requested by the insurer to assess your impairment independently of your treating physician. IME ratings frequently differ from treating physician ratings — often lower. If you disagree with the IME rating, you have 30 days to challenge it by filing with the Illinois Workers' Compensation Commission. Legal representation is strongly recommended at this stage.
In Illinois, the Schedule injuries & wage differential system determines whether your injury is treated as a scheduled injury (specific body part with a fixed maximum number of benefit weeks) or an unscheduled injury (whole-body or wage-loss basis). Scheduled injuries are generally more predictable; unscheduled injuries may provide higher awards for workers with significant wage loss.
Permanent partial disability (PPD) payments in Illinois can be paid as a lump sum (common in settlements) or as weekly payments over a defined number of weeks based on the PPD schedule and impairment rating. Permanent total disability (PTD) benefits, for workers unable to perform any work, may continue for life — up to $1,897 per week.
