Introduction
The whole body impairment rating for a work place injury is critical to the amount of work injury benefits that an injured worker will receive for their work place injury. The information contained in an impairment rating chart can be overwhelming and can present many challenges during an assessment.
How to deal with the information from an impairment rating chart in order to receive the proper work injury benefits?
Understand Whole Body Impairment Ratings
The whole body impairment rating chart is very confusing. Many of the ratings are very important in order to receive the proper amount of support and disability and financial compensation for individuals that have been injured. The WBI score takes into account how an injury will affect the entire body and how it will affect an individual’s function as a whole. Understanding the whole body impairment rating chart is very important for individuals that have been injured as well as their legal representation.

Access and Interpret the Impairment Rating Chart
Have you been confused about the way your workplace injury is to be compensated? In order to determine your full body impairment your state likely uses a whole body impairment rating chart for your state found on your state's workers' compensation board's website or elsewhere on the web. We will cover each step to figuring out your body impairment rating.
- Identify the Body Part: Use the table above to locate the Impairment associated with the body part(s) affected by the injury. Most of the Impairment charts identify specific amounts of impairment for various parts of the body.
- Review the disability percentages for the corresponding body parts to arrive at a total whole body permanent partial disability rating. Using the chart above as an example, the minor finger amputation would be rated at 5% disability while a serious back injury would likely be rated at 30% or greater disability. Again, refer to the whole body impairment rating chart for the proper compensation period for different types of injuries such as 200 weeks for complete loss of a hand.
- Special Circumstances - age, work, pre-existing conditions, etc. - which affect impairment rating(s) in some of the charts. As always, a disability assessment cannot be completed until the worker’s condition has reached a fixed state and can get no better - i.e. when the worker is at Maximum Medical Improvement (MMI).
- Document Your Body Parts: It is very important that you keep a running log of each body part that you feel you have lost some function and the degree of loss for each. The log will be an essential document to refer to in the assessment of benefits to your work injury and will help you ensure that all of your impairments are accurately assessed. Further, if you feel that your doctor has under stated your degree of impairment, you have a right to a second opinion.
- Understand how your benefits will be affected: In accepting your impairment rating(s) for your body part(s) you may be giving up future medical treatment for that part of your body. It is wise to place a value on future medical treatment for that body part prior to settling your claim for that body part.

Calculate Impairment Percentages Using the Chart
Disability assessments can be confusing and awkward to deal with and we will guide you through the whole process.
Make a list of your medical records and make sure you have all the evidence needed to claim disability benefits as an injured worker.
Ensure your injuries have reached a point of stabilization and you have reached Maximum Medical Improvement (MMI).
Note: The percentage disability assessed to your knee injury will also determine the amount of compensation for his/her injury. In the example above a 20% disability to the knee would attract compensation for this portion of his/her overall injury.
When considering a number of injuries which have occurred in separate incidents, each injury will have been assessed on an individual basis using the same scale to measure disability. This means that each of those percentages will have to be taken into account when calculating the combined percentage for all of your injuries. The following chart outlines the combined values for different percentages of injury.
Don’t forget the percentage that you have been assessed with. Remember that an injured worker is currently receiving three weeks of Income Benefits (IIBs) per 1% disability assessed for their injury. Rights of the injured worker in respect to a workplace injury where fault is not an issue need to be made aware.
If you feel that your assessment has failed to properly reflect your injury or the resulting amount of disability then your assessment can be contested by written correspondence within 90 days of the assessment. We would robustly argue your case to try to achieve a fair result. In many cases, we would represent you in contesting a claim decision and this can often be necessary if your claim is refused.

Address Challenges in Impairment Rating Assessments
Need help with your Impairment Rating Assessment?
- Request an Alternative Assessment: If you have any concerns with your first Impairment Rating assessment, you may have an Alternative Assessment performed by another expert (generally a Medical Examiner) as permitted by statute. This assessment may more accurately determine your degree of work-related impairment than your first assessment. The Impairment Rating assessments (utilized in accordance with the Whole Body Impairment Rating Formula Chart, WBIRFCH) express the degree of work-related impairment suffered by an injured worker in terms of a percentage of impairment of maximum potential function which translates to the worker’s degree of work-related medical impairment and resulting reduction in ability to perform work as compared to his or her pre-injury work capabilities.
- Document Everything: Write down and keep a record of every single one of your medical treatments and all of your communications with your insurance company. Such documentation can be very useful to contest an Impairment Income Benefits evaluation and to present proof and supporting evidence of the degree of symptoms, test results, treatment limitations and work limitations that affect you in your daily life. Such factors are used in rating your whole body impairment and in creating your WBIRFCH Impairment Rating Chart.
