Section 287.067.1 RSMo defines an occupational disease, as follows:
In this chapter the term 'occupational disease" is hereby defined to mean, unless a different meaning is clearly indicated by the context, an identifiable disease arising with or without human fault out of and in the course of the employment. Ordinary diseases of life to which the general public is exposed outside of the employment shall not be compensable, except where the diseases follow as an incident of an occupational disease as defined in this section. The disease need not to have been foreseen or expected but after its contraction it must appear to have had its origin in a risk connected with the employment and to have flowed from that source as a rational consequence.
Employee's claim for compensation alleges a left shoulder injury by repetitive use with a date of injury of August 16, 2005. But the record suggests (and we so find) that employee did not seek any treatment for left shoulder issues until February 2009. As noted in the administrative law judge's award, employee began seeing Dr. James Schaberg for right shoulder problems in December 2005. Although employee continued to see Dr. Schaberg for evaluations and to receive cortisone injections in his right shoulder, Dr. Schaberg's records do not contain any suggestion that employee suffered from left shoulder symptoms until February 20, 2009. In Dr. Schlafly's report of February 12, 2008, he made only passing mention of the left shoulder, reciting employee's suspicion that he was developing arthritis in his left shoulder, noting some restricted range of motion, and suggesting additional evaluation in the form of diagnostic studies.
The courts have linked the "date of injury" in occupational disease cases to the date the disease first becomes "compensable," which typically has been interpreted to mean the date an employee first experiences some disability from the disease. See Garrone v. Treasurer of State, 157 S.W.3d 237, 242 (Mo. App. 2004)(holding that an employee's carpal tunnel syndrome did not become a compensable injury until the date he missed work for surgery, as he worked without restriction up until that date), and Coloney v. Accurate Superior Scale Co., 952 S.W.2d 755, 759 (Mo. App. 1997)(noting that "Missouri courts have interpreted section 287.063 to provide that an employee with an occupational disease is 'injured' ... when the disease causes a 'compensable injury'").
At oral argument in this matter, employee's counsel suggested that employee could have been suffering from symptoms referable to his left shoulder prior to August 16, 2005, but chose to focus on seeking treatment for his more pressing right shoulder and carpal tunnel issues instead. This may be so, but the record before us simply does not support such a finding. Employee, in his own testimony, was unable to persuasively identify the timing of the onset of his left shoulder symptoms with any specificity.
In his report of July 9, 2013, Dr. Schlafly opined that employee's work duties caused his bilateral shoulder impingement syndrome and rotator cuff tendonitis, but did not specifically indicate (1) that employee suffered any identifiable disease of the left shoulder up to and including August 16, 2005, or (2) that employee's work caused such a condition.
