Eva Mae Jefferies v. McKee Foods

In this workers' compensation case, the employer, McKee Foods Corporation, has appealed the trial court's award of 50% permanent partial disability to the body as a whole to the employee, Eva Mae Jefferies. The trial court's award of benefits was based on a medical impairment rating calculated under the Fifth Edition of the American Medical Association Guides to the Evaluation of Permanent Impairment ("AMA Guidelines"), which was in effect at the time of trial. The employer's appeal was transferred to the full Supreme Court prior to a decision by the Special Workers' Compensation Appeals Panel. The employer contends in this Court that the trial court should have applied a medical impairment rating calculated under the Fourth Edition of the AMA Guidelines because the Fourth Edition was the edition in effect when the employee reached maximum medical improvement. Thus, the sole question for this Court is whether the trial court erred in awarding benefits using a medical impairment rating calculated under the Fifth Edition of the AMA Guidelines. After carefully examining the record and the relevant authorities, we find that in determining the extent of the employee's vocational disability, the trial court should have used a medical impairment rating calculated under the Fourth Edition of the AMA Guidelines. Accordingly, the judgment of the trial court is reversed. The case is remanded for further proceedings consistent with this opinion.
