The employer appealed a Case Manager's decision granting the worker initial entitlement for an umbilical hernia and ongoing Loss of Earnings (LOE) benefits related to surgical repair.
The worker felt a pop in their abdomen while bending and reaching into a van at work.
The employer argued the hernia was a pre-existing congenital condition and that the mechanism of injury was insufficient to cause it.
The Appeals Resolution Officer applied the five-point check system under WSIB Policy 11-01-01 and found the injury was compatible with the accident history.
The medical evidence did not support the employer's assertion that the hernia was pre-existing.
The appeal was dismissed, and entitlement to the hernia, surgery, and related LOE benefits was upheld.
