Section 23:1209 - Prescription; timeliness of filing; dismissal for want of prosecutionA.(1) In case of personal injury, including death resulting therefrom, all claims for payments shall be forever barred unless within one year after the accident or death the parties have agreed upon the payments to be made under this Chapter, or unless within one year after the accident a formal claim has been filed as provided in Subsection B of this Section and in this Chapter.(2) Where such payments have been made in any case, the limitation shall not take effect until the expiration of one year from the time of making the last payment, except that in cases of benefits payable pursuant to R.S. 23:1221(3) this limitation shall not take effect until three years from the time of making the last payment of benefits pursuant to R.S. 23:1221(1), (2), (3), or (4).(3) When the injury does not result at the time of or develop immediately after the accident, the limitation shall not take effect until expiration of one year from the time the injury develops, but in all such cases the claim for payment shall be forever barred unless the proceedings have been begun within three years from the date of the accident.(4) However, in all cases described in Paragraph (3) of this Subsection, where the proceedings have begun after two years from the date of the work accident but within three years from the date of the work accident, the employee may be entitled to temporary total disability benefits for a period not to exceed six months and the payment of such temporary total disability benefits in accordance with this Paragraph only shall not operate to toll or interrupt prescription as to any other benefit as provided in R.S. 23:1221.B. Any claim may be filed with the assistant secretary, office of workers' compensation, by delivery or by mail addressed to the office of workers' compensation. The filing of such claims shall be deemed timely when the claim is mailed on or before the prescription date of the claim. If the claim is received by mail on the first legal day following the expiration of the due date, there shall be a rebuttable presumption that the claim was timely filed. In all cases where the presumption does not apply, the timeliness of the mailing shall be shown only by an official United States postmark or by official receipt or certificate from the United States Postal Service made at the time of mailing which indicates the date thereof.C. All claims for medical benefits payable pursuant to R.S. 23:1203 shall be forever barred unless within one year after the accident or death the parties have agreed upon the payments to be made under this Chapter, or unless within one year after the accident a formal claim has been filed with the office as provided in this Chapter. Where such payments have been made in any case, this limitation shall not take effect until the expiration of three years from the time of making the last payment of medical benefits.D. When a petition for compensation has been initiated as provided in R.S. 23:1310.3, unless the claimant shall in good faith request a hearing and final determination thereon within five years from the date the petition is initiated, that claim shall be barred as the basis of any claim for compensation under the Worker's Compensation Act and shall be dismissed by the office for want of prosecution, which action shall operate as a final adjudication of the right to claim compensation thereunder.Amended by Acts 1975, No. 583, §7, eff. 9/1/1975.
