To establish the process for adjudicating claims where pre-existing conditions exists.
POL 12/2017, Pre-Existing Conditions – Aggravation or Acceleration establishes guidelines for injury claims where pre-existing conditions exist.
- Once Operations staff determine the worker has a pre-existing condition that may affect their recovery from the work-related injury, they must determine:
- The extent of the work-related injury.
- The extent of the aggravation or acceleration of the pre-existing condition by the work-related injury.
- If the worker has recovered from the work-related injury.
- Operations staff will gather information about the pre-existing condition from:
- The worker.
- Health care providers by obtaining medical confirmation of the pre-existing condition.
- Past and present employers and coworkers, and other insurers, if necessary.
- Operations staff will review:
- Any history of prior problems in the same or nearby areas of the body as the work-related injury.
- The effect(s) of any pre-existing condition on the worker leading up to the work injury (i.e., pre-injury status).
- Relevant medical reports regarding the worker’s pre-existing condition.
- Operations staff may request a WCB Medical Consultant’s opinion to help clarify the extent of a work-related injury in relation to a pre-existing condition.
- Operations staff will notify workers when compensation benefits will be terminated once they have recovered from the injury and are able to return to pre-injury employment (POL 17/2010, Termination of Compensation Benefits – Notice).
