All companies are required by law post it workers compensation notice poster in a visible area in then work environment. This poster will have contact information, who to call in the event of an injury, and who the injury must be reported to. This poster also will have the carrier of the Worker's Compensation insurance including phone numbers. In most cases the employee must report to their direct supervisor that it injury has occurred on the job. It is the supervisor's responsibility to inform the insurance carrier that an injury has occurred and a Worker's Compensation claim will be open for that coworker. Once the claim is open the insurance carrier will take care of all medical bills associated with that open claim. If your daughter did not report the injury to her supervisor then you would be responsible for the bill. If your daughter did report the incident to her supervisor then the company will be responsible for the bill. If your daughter did report the injury then you need to try to get contact information for a corporate office, employee relations department, or the Workmen's Comp. carrier if the direct employees that you spoken to have not been helpful. If it's a smaller company Or a mom-and-pop it may be more difficult to get assistance. But if this a decent size company you should be able to get some contact information on the Internet or other sources that will allow you to call speak to someone that would be responsible for assisting you with this claim.
