Pursuant to § 287.430 RSMo, a claim for occupational disease must be filed within two years after the date of injury or death or within two years of payment of some element of compensation: "[N]o 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,..."
Until August 28, 2005, the two year period did not begin to run until it became "reasonably discoverable and apparent that a compensable injury has been sustained." § 287.063.3 RSMo (2004). The question as to when a compensable injury becomes reasonably discoverable and apparent is a question of fact to be determined by the Commission. Mann v. Supreme Express, 851 S.W.2d 690, 692 (Mo. App. 1993). Under the law in effect before August 28, 2005, the statute of limitations in an occupational disease case starts to run when: (1) an employee is no longer able to work due to the occupational disease; (2) an employee must seek medical advice and is advised that he can no longer work in the suspected employment; or (3) the employee experiences some type of disability that is compensable. Rupard v. Kiesendahl, 114 S.W.3d 389 (Mo. App. 2003), overruled on other grounds by Hampton v. Big Boy Steel Erection, 121 S.W.3d 220 (Mo. banc 2003).
Within this context, a disability is the inability to do something; the deprivation or lack of physical, intellectual, or emotional capacity or fitness; the inability to pursue an occupation or perform services for wages because of physical or mental impairment. Loven, 63 S.W.2d at 284. It is not necessary for an employee to miss work before that employee can recover on an occupational disease claim. Coloney v. Accurate Superior Scale, 952 S.W.2d 755 (Mo. App. 1997), overruled on other grounds by Hampton v. Big Boy Steel Erection, 121 S.W.3d 220 (Mo. banc 2003). Rather, an employee with an occupational disease is compensably injured when the employee suffers a demonstrated loss of earning capacity, such as an inability to perform various vocational tasks. Loven, 63 S.W.3d at 284-285; Coloney, 952 S.W.2d at 760. Requiring that the harm tangibly affect the
employee's earning ability upholds the intent of the Law, which is to provide indemnity for loss of earning power and disability to work. Coloney, 952 S.W.2d at 760.
Generally, such a condition becomes apparent when an employee is medically advised that he or she can no longer physically continue in the work environment. A compensable injury occurs when the disease causes the employee to become disabled and unable to work. Wiele v. National Super Markets, Inc., 948 S.W.2d 142 (Mo. App. 1997), overruled on other grounds by Hampton v. Big Boy Steel Erection, 121 S.W.3d 220 (Mo. banc 2003).
An employee is not expected to file a workers' compensation claim until the employee has reliable information that his or her condition is the result of his or her employment. The employee is entitled to rely on a physician's diagnosis of the employee's condition rather than his or her own impressions. This rule is not, however, absolute. Under certain circumstances, it can be foreseen the time should begin to run without having an expert's opinion in the employee's hands. The facts of each case will have to be determined on a case-by-case basis in this uncertain area, all under the existing doctrine of construing the workers' compensation law liberally. Rupard, 114 S.W.3d at 396-397.
Applying the analysis described above, we conclude that as of August 27, 2005, employee had sustained no disability triggering the running of the statute of limitations.
The legislature changed the tolling provision for the filing of occupational disease claims with the 2005 amendments to the Workers' Compensation Law. Beginning August 28, 2005, the two year period begins to run when "it becomes reasonably discoverable and apparent that an injury has been sustained related to such exposure,..." § 287.063.3 RSMo (2005). The evidence reveals that employee was aware her carpal tunnel syndrome was related to her nursing duties as of August 28, 2005.
"[T]here is no vested right in the maintenance in force of the statute in effect when the claim accrued. It is possible to shorten the statute of limitations applicable to an existing claim. If any such attempt is made, however, those who have pending and unbarred claims at the time the new statute becomes effective must be afforded a reasonable time within which to file suit." Goodman v. St. Louis Children's Hospital, 687 S.W.2d 889, 891 (Mo. 1985)
"No person can claim a vested right in any particular mode of procedure for the enforcement or defense of his rights. Where a new statute deals with procedure only, prima facie it applies to all actions [including] those which have accrued o
