Policy
A worker who has a work-related permanent impairment is entitled to a non-economic (NEL) benefit based on the degree of his/her work-related permanent impairment determined by the decision-maker. The decision-maker uses a prescribed rating schedule, all relevant health care information in the claim file and, if required, a report from an independent medical assessment, to determine the degree of permanent impairment.
If a condition other than the work-related injury/disease is contributing to the total degree of impairment to the area, the degree of impairment caused by the work-related injury/disease is determined.
If a determination results in a zero percent rating, there is no permanent impairment and no entitlement to a NEL benefit.
Principles
Workers are entitled to compensation for their non-economic loss if a work-related injury/disease results in a permanent impairment.
Purpose
The purpose of this policy is to set out what a NEL benefit compensates for and how the degree of permanent impairment is determined.
Guidelines
NEL Benefit
A NEL benefit compensates for work-related permanent impairments that have been determined to exist per 11-01-05, Determining Permanent Impairment.
A NEL benefit is payable regardless of whether the permanent impairment affects a worker’s ability to work.
Degree of permanent impairment
General
A prescribed rating schedule is used to determine the degree of the permanent impairment once a permanent impairment has been identified per 11-01-05, Determining Permanent Impairment.
If a type of impairment is not listed in the prescribed rating schedule, the decision-maker uses criteria in the prescribed rating schedule for the body parts, systems, or functions which are most similar to the worker's impairment.
The degree of permanent impairment is expressed as a percentage of total permanent impairment of the whole person.
For certain permanent impairments, there are exceptional rating methods. See

Health care information on file
The decision-maker determines the degree of the permanent impairment by considering the health care information available in the claim file. If the worker’s physician or other health care professional cannot provide sufficient health care information to determine the degree of the worker’s permanent impairment, the decision-maker may arrange for the worker to attend an independent medical assessment.
If the worker attends an independent medical assessment, the WSIB sends a copy of the assessment report to the worker.
An employer may request a copy of the independent medical assessment report without there being an issue in dispute. If requested, the worker is notified and given 21 days to object to the release of the report. If the worker does object, the WSIB follows the guidelines set out in 21-02-02, Disclosure of Claim File Information (Issue In Dispute).
Decision-makers may use information in the independent medical assessment to assist in determining a worker's entitlement to other benefits and services.
If a worker suffers a wage loss in order to attend a NEL assessment, they are entitled to compensation for the wage loss, see 18-05-10, Wage Loss for NEL Assessment.
In cases where the worker cannot attend an independent medical assessment, the WSIB may modify the process normally followed to determine the degree of permanent impairment. Examples of such cases are
Multiple impairments
In some cases, more than one area of permanent impairment may be considered at the same time for the purposes of determining the overall degree of permanent impairment. The decision-maker rates each impairment according to the prescribed rating schedule and then combines the ratings using the prescribed rating schedule.
Determinations post-final benefit review
A NEL benefit can be determined post-final future economic loss (FEL) review (60 month post-initial FEL determination) or post-final LOE review (72 months post-injury) if
For entitlement to NEL redeterminations post-final benefit review, see 18-05-09, NEL Redeterminations.
If a permanent impairment has been established post-final FEL/LOE review, the FEL/LOE benefit may also be reviewed. The FEL/LOE benefit review period continues for a period of up to 24 months from the date the resulting NEL benefit is processed. If the determination of the degree of permanent impairment results in a zero rating, the review ends as of the date of that determination. See 18-04-20, Final FEL Benefit Review or 18-03-06, Final LOE Benefit Review.
Pre-existing conditions and prior work-related permanent impairments
When determining the degree of work-related permanent impairment for workers who have a pre-existing condition, see 15-02-03, Pre-existing Conditions, or a prior work-related permanent impairment, the decision-maker
Pre-existing condition affecting a different area of the body
If a pre-existing condition affects a different area of the body, the decision-maker rates the new work-related impairment on its own without any reduction for the pre-existing condition.
Pre-existing condition affecting the same body area
To factor out a pre-existing condition, it must be established that it is contributing to the degree of impairment to the same area of the body as the work-related permanent impairment.
To establish this, the evidence must show that the pre-existing condition, on its own, would result in an impairment rating. The pre-existing existing condition does not need to have produced periods of impairment or disease requiring health care, or have caused a disruption in employment, in order to factor out its rating from the total impairment rating.
If it is established that a pre-existing condition is contributing to the degree of total impairment to the same area of the body, the decision-maker
If the pre-existing condition cannot be rated according to the prescribed rating schedule, the medical significance of the pre-existing condition is determined based on the clinical evidence and the decision-maker reduces the total impairment rating of the area according to the determination.
If the significance of the pre-existing condition is
If it is determined that a pre-existing condition has been permanently aggravated by a work-related injury/disease, only the permanent impairment rating for the pre-existing condition that existed at the time of injury/disease is offset.
Pre-existing NEL benefit affecting a different area of the body
If a worker with a pre-existing NEL benefit has a new permanent impairment that affects another area of the body, the decision-maker determines the second NEL benefit by
Pre-existing NEL benefit affecting the same area of the body
If a worker with a pre-existing NEL benefit has a new injury that results in an increased impairment to the same area of the body, the decision-maker determines the second NEL benefit by
Pre-existing NEL to the same and different body areas
If a worker with a pre-existing NEL benefit has a new injury resulting in both an increased impairment to the same area of the body, and a new impairment to a different area of the body, the decision-maker determines the second NEL benefit by
Pre-existing permanent disability pension affecting a different area of the body
If a worker suffered an injury before January 2, 1990 which resulted in a permanent disability (PD) pension, and then suffers a work-related permanent impairment to a different body area on or after January 2, 1990, the decision-maker rates the post-January 2, 1990 impairment on its own.
Pre-existing PD pension affecting the same area of the body
If a worker suffered an injury before January 2, 1990 which resulted in a PD pension, and then suffers a work-related permanent impairment to the same body area on or after January 2, 1990, the decision-maker
Post-accident non-work-related condition
When determining the degree of permanent impairment where a post-accident non-work-related condition exists, the decision-maker
Post-accident non-work-related conditions include
For more information about post-accident non-work-related conditions, see 15-05-03, Non-Work-Related – Second Accidents and 15-06-08, Adjusting Benefits Due to Post-accident, Non-work-related Change in Circumstances.
Loss of earnings benefits
The degree of permanent impairment determined does not affect entitlement to any loss of earnings (LOE) benefits that may be payable, except in cases where the degree of impairment is determined to be zero, see Zero percent NEL rating section below.
Zero percent NEL rating
A zero percent NEL rating indicates that the worker does not have an assessable permanent impairment.
As a result, FEL benefits and supplements, if any, or LOE benefits, are paid until the worker is notified in writing, up to a maximum of 2 weeks, see 18-04-15, Effect of a 0% NEL Rating on FEL Benefits, and 18-03-02, Payment and Reviewing LOE Benefits (Prior to Final Review).
Payment of NEL benefit
For information on how the decision-maker calculates and pays NEL benefits resulting from an initial determination, including the special cases noted above, see 18-05-04, Calculating NEL Benefits.
Redeterminations
If the work-related condition significantly and permanently deteriorates after a permanent impairment is rated, the worker can apply for a redetermination, see 18-05-09, NEL Redeterminations.
Application date
This policy applies to all decisions made on or after November 1, 2014, for accidents on or after January 2, 1990.
Policy review schedule
This policy will be reviewed within five years of the application date.
