La. Stat. tit. 46 § 13
Where a patient in any of the state charity hospitals or in any veterans administration hospital in the state comes within the provisions of the employer's liability laws, the superintendent or the director may make appropriate charges for services rendered to the patient, in accordance with charges of other first class hospitals, including physicians' and surgeons' fees; and the patient, the employer of the patient, and the compensation insurer of the employer shall be liable therefor in solido. The superintendent or the director of the hospital shall give notice to the employer or the insurance company that the patient is being treated and that charges will be made therefor; provided that failure to give this notice shall not relieve the employer or the insurance company from liability when notice has been otherwise received.
