As a general rule, if an employee is going to or leaving from work and falls in the company parking lot due to the presence of some foreign object such as a parking barrier, snow, ice, or any other item that causes the fall, that claim should be covered by worker’s compensation. If you have a denied claim that took place in the company parking lot, there is a good chance your claim should be approved and that the insurance company is incorrect in its denial. The exception might be if your fall happens due to a “unknown reason”. If you fall and tell the insurance company after the fall that you have no idea why you fell or just tripped over your own feet, that might not be covered by worker’s compensation. That is a factually sensitive question and the outcome of your case will depend on the exact fact scenario.
