Employees who sustain traumatic injuries while working are entitled to emergency medical care at the expense of the employer. If you are injured on the job, your medical expenses, including ambulance, emergency room care and subsequent hospitalization, should be covered by workers compensation insurance carried by your employer. State laws generally define a work-related injury to include any injury that occurs while you are actually on the premises or doing any duty for the benefit of your employer. This also includes certain errand duties, if done at the request of, or for the benefit of, your employer. Injuries that occur during an automobile accident while you are on the job would be covered by workers compensation insurance. Some states insist certain requirements be met in order for emergency care to be paid for by workers compensation.
