§ 11-9-802. Installments

(c) If any installment payable under the terms of an award is not paid within fifteen (15) days after it becomes due, there shall be added to such unpaid installment an amount equal to twenty percent (20%) thereof, which shall be paid at the same time as, but in addition to, the installment unless review of the compensation order making the award is had as provided in §§ 11-9-711 and 11-9-712.
(d) Medical bills are payable within thirty (30) days after receipt by the respondent unless disputed as to compensability or amount.
(e) In the event that the commission finds the failure to pay any benefit is willful and intentional, the penalty shall be up to thirty-six percent (36%), payable to the claimant.
