(b) Except as otherwise permitted by law, an employer, carrier, or third-party administrator shall not interfere or attempt to interfere with the selection by an injured employee of, or treatment by, an authorized medical provider, including by directing or attempting to direct that the injured employee seek treatment from a specific provider or type of provider selected by the employer, carrier, or third-party administrator.
