The degree of disability is a key factor in determining how much compensation a worker is entitled to under workers' compensation laws. It refers to the extent to which the injury affects the worker’s ability to perform normal work activities and whether the disability is temporary or permanent. The degree of disability is typically determined through a medical evaluation conducted by a physician or disability evaluator, using specific guidelines or disability rating systems.
The degree of disability is usually assessed by a licensed medical professional who examines the worker's injury, treatment history, and recovery progress.
In most cases, doctors, orthopedic surgeons, neurologists, or other specialists in the field relevant to the injury will provide an assessment based on clinical observations and diagnostic tests.
To determine the degree of disability, workers' compensation systems typically rely on a disability rating or impairment rating system.
This rating evaluates the permanent loss of function caused by the injury. It is usually expressed as a percentage of the total body function that is lost or impaired due to the injury.
In many countries, systems like the American Medical Association’s (AMA) Guides to the Evaluation of Permanent Impairment are used to provide a standardized method for rating the severity of a disability. This guide considers the specific body part injured, the impact on function, and the medical evidence available.
The more severe the injury, the higher the disability rating. For example, the loss of a limb or permanent paralysis would be rated much higher than a temporary back injury.
Temporary disabilities (e.g., sprains, strains, fractures) generally receive a temporary disability rating, while permanent disabilities (e.g., loss of vision, limb, or long-term impairment) are assessed with a permanent disability rating.
Different body parts are assigned specific impairment values, and the loss of certain body parts (such as fingers, limbs, or eyes) may be considered more significant than others.
The degree to which the injury affects the worker’s ability to return to their previous job, perform other tasks, or engage in daily life activities is a crucial factor in determining the disability degree.
If the injury is expected to heal over time, it may result in a lower disability rating, whereas permanent conditions or disabilities that do not improve may result in higher ratings.
For temporary disabilities, the degree is generally based on how long the worker is expected to be off work. In some systems, temporary partial disability refers to cases where the worker can still work but with limitations, while temporary total disability applies when the worker is completely unable to work for a certain period due to the injury.
If the worker’s disability is permanent but only partial (e.g., the loss of a finger), the disability rating will be lower, and compensation is typically based on the percentage of loss of function.
If the worker is permanently unable to work in any capacity due to the injury (e.g., complete paralysis, loss of both hands), the disability is rated as total, and compensation will be higher to reflect the complete loss of the ability to earn a living.
In some jurisdictions, disability schedules are used to determine compensation rates. These schedules assign a specific percentage of impairment for each body part based on standard criteria. For example, the loss of an arm may be rated at 60% impairment, while the loss of a finger may be rated at 10% impairment.
The percentage of disability is multiplied by the worker’s average weekly wage (or other compensation base) to determine the compensation amount. Higher percentages of disability lead to higher compensation.
In complex cases, such as spinal injuries or brain damage, expert medical testimony may be required to assess the degree of disability accurately. The testimony may also be used in legal proceedings if the worker disputes the rating given by the insurer or employer.
A worker suffers a fractured leg that requires surgery but is expected to recover fully. The worker may receive a temporary partial disability rating if they are unable to perform their usual work but can recover after a few months.
A worker loses a finger in an industrial accident. The disability rating would be based on a percentage loss of the total body function, with compensation determined by the percentage of impairment and the worker's wages.
A worker is permanently disabled due to paralysis from the waist down. The disability rating would be very high (often close to 100%), and the worker would be entitled to permanent total disability compensation, which may include long-term support for lost wages and additional benefits for life.
The degree of disability directly affects the compensation the injured worker will receive. A higher degree of disability usually results in:
The degree of disability for workers' compensation is determined based on several factors, including the type and severity of the injury, its impact on work capacity, and whether the disability is temporary or permanent. Medical evaluations, impairment rating systems, and disability schedules are used to calculate the disability rating, which then determines the level of compensation the injured worker is entitled to. The higher the degree of disability, the higher the compensation, especially in cases of permanent or total disabilities.
