341. The Commission shall claim from an employer who is personally liable for the payment of benefits to a worker the amount of benefits for medical aid and rehabilitation it has furnished to the worker, by means of a notice in writing indicating(1) the worker’s name;
(2) the date, nature and amount of benefits provided; and
(3) the employer’s right to apply for review of the decision.
For the purposes of payment, computation of interest and determining the due date and, where such is the case, contestation, the notice constitutes a notice of assessment.
