The employee cannot seek medical care with any doctor.  The employer’s obligation to pay for the medical care is limited to treatment provided by a physician or other health care provider authorized by the employer or its insurer in advance, as in before any injury ever takes place.  Employers are required by law to maintain and post in a visible place at work a panel (list) of authorized physicians with whom its employees can treat in the event of an injury.  If the employer fails to post such list and explain it to the employees, only then the employee has the right to select any physician of his choosing paid for by the employer or insurer.
