What evidence supports maximum medical improvement in workers compensation cases? Macy's Southtowne v. Labor Commission Explained

In Macy’s Southtowne v. Labor Commission, the Utah Court of Appeals addressed key evidentiary standards for determining maximum medical improvement (MMI) and work capacity in permanent total disability cases. The case provides important guidance on how substantial evidence supports Labor Commission findings.

Background and Facts

Jensen sustained a lower-back injury while working as a sales associate for Macy’s in April 2007. After accepting liability and paying temporary benefits, the employer agreed to permanent partial disability compensation based on a 13% impairment rating. Jensen attempted to return to work but could not continue due to chronic pain and medication side effects. Following multiple surgeries including discectomy, fusion surgery, and spinal cord stimulator implantation, Jensen applied for permanent total disability benefits in 2015.

Key Legal Issues

The employer challenged two Commission findings: (1) that Jensen reached maximum medical improvement, and (2) that she could not perform other work reasonably available. Both challenges were reviewed under the substantial evidence standard, as they constituted attacks on the Commission’s factual determinations.

Court’s Analysis and Holding

The Court of Appeals affirmed both findings. Regarding MMI, the court clarified that the Commission properly found Jensen reached MMI in 2015 based on medical expert opinions, not specifically on July 2, 2015—the latter date marked when benefits began, not MMI. The court explained that MMI depends on whether the condition will materially improve, not whether treatment continues.

For the “other work reasonably available” element, the court relied on Quast v. Utah Labor Commission, noting that evidence of impairment extent, combined with the Commission’s “good common sense and general understanding of the job market,” can satisfy the claimant’s burden. Jensen’s functional capacity evaluation showed she could work only 0-3 hours per day at sedentary levels and could not complete tasks at constant capacity.

Practice Implications

This decision reinforces that substantial evidence review requires deference to Commission findings when reasonable minds could differ. Practitioners should distinguish between MMI dates and benefit commencement dates, and understand that proving inability to perform “other work reasonably available” does not require exhaustive job market surveys when severe functional limitations are established through medical evidence.
