287.430. Limitation as to action, exception. — Except for a claim for recovery filed against the second injury fund, no proceedings for compensation under this chapter shall be maintained unless a claim therefor is filed with the division within two years after the date of injury or death, or the last payment made under this chapter on account of the injury or death, except that if the report of the injury or the death is not filed by the employer as required by section 287.380 , the claim for compensation may be filed within three years after the date of injury, death, or last payment made under this chapter on account of the injury or death. The filing of any form, report, receipt, or agreement, other than a claim for compensation, shall not toll the running of the periods of limitation provided in this section. The filing of the report of injury or death three years or more after the date of injury, death, or last payment made under this chapter on account of the injury or death, shall not toll the running of the periods of limitation provided in this section, nor shall such filing reactivate or revive the period of time in which a claim may be filed. A claim against the second injury fund shall be filed within two years after the date of the injury or within one year after a claim is filed against an employer or insurer pursuant to this chapter, whichever is later. In all other respects the limitations shall be governed by the law of civil actions other than for the recovery of real property, but the appointment of a conservator shall be deemed the termination of the legal disability from minority or disability as defined in chapter 475 . The statute of limitations contained in this section is one of extinction and not of repose.

Prior revision: 1929 § 3337 (1965) There is no legislative intent expressed in this section to extinguish completely a workmen's compensation claim if not filed within the period provided by the statute. Welborn v. Southern Equipment Company (Mo.), 395 S.W.2d 119. (1966) While the furnishing of an elastic bandage by the employer's nurse constituted medical aid to relieve from the effects of injury, the mere wearing of that elastic bandage did not toll the statute of limitations while wearing the bandage. Morgan v. Krey Packing Co. (A.), 403 S.W.2d 668. (1967) The word "treatment" does not include mere physical examination or mere diagnosis. Bryant v. Montgomery Ward & Co. (A.), 416 S.W.2d 195. (1968) The limitation period does not begin to run until it becomes reasonably discoverable and apparent that a compensable injury has been sustained. Williams v. S.N. Long Warehouse Co. (A.), 426 S.W.2d 725. (1976) Held, advice to treat ankle with "warm soaks" constituted "medical treatment" and that such treatment constituted "payment" sufficient to toll statute of limitations. Faries v. ACF Industries, Inc. (A.), 531 S.W.2d 93. (2002) Use of term "extinction" indicates legislative intent that the two-year limitation is substantive and jurisdictional rather than procedural and waivable. Marston v. Juvenile Justice Center, 88 S.W.3d 534 (Mo.App.W.D.).
