Missouri, 822 S.W.2d 504, 508 (Mo. App. E.D. 1991)(interpreting a doctor's testimony of employee's maximum treatment potential to mean maximum medical improvement); Cooper, 955 S.W.2d at 575 (using the term maximum medical progress to define the point where no further progress is expected for an employee's condition).
After reaching the point where no further progress is expected, it can be determined whether there is either permanent partial or permanent total disability and benefits may be awarded based on that determination. One cannot determine the level of permanent disability associated with an injury until it reaches a point where it will no longer improve with medical treatment. Furthermore, an employers' liability for permanent partial or permanent total disability does not run concurrently with their liability for temporary total disability.
Although the term maximum medical improvement is not included in the statute, the issue of whether any further medical progress can be reached is essential in determining when a disability becomes permanent and thus, when payments for permanent partial or permanent total disability should be calculated.
Cardwell v. Treasurer of Mo., 249 S.W.3d 902, 910 (Mo. App. 2008).
Employer's plant closed on June 12, 2000; there is no other significance to this date. The record reveals that employee continued to receive treatment related to his 1999 occupational disease until March 24, 2004. The parties, in fact, stipulated that employee reached maximum medical improvement on March 24, 2004, the date that Dr. Coin released employee following treatment for the occupational disease. As of June 12, 2000, employee had not even undergone carpal tunnel or trigger thumb surgeries and releases, so any determination of permanent disability related to the primary injury was clearly premature.
Given the foregoing, the administrative law judge's determination that employee was permanently and totally disabled as of June 12, 2000, is erroneous as contrary to the evidence and the stipulation of the parties regarding maximum medical improvement. We conclude that employee was permanently and totally disabled on March 24, 2004. Accordingly, permanent total disability payments should commence from the Second Injury Fund beginning March 24, 2004.
