Background

Michael Wooff, a longtime drywall worker for Menefee Drywall, reported work-related pain in August 2019. He underwent three right-shoulder surgeries and two cervical-spine surgeries, and received treatment for depression. The parties stipulated that his shoulder injury was work-related but disputed the compensability of his neck and mental-health conditions.

A deputy workers’ compensation commissioner found all three conditions compensable and awarded benefits based on a 55% industrial disability. On intra-agency appeal, however, the commissioner concluded that Menefee’s 2021 offer of a $60,000 superintendent position limited Wooff’s recovery to functional impairment under Iowa Code section 85.34(2)(v). The commissioner awarded benefits based on a 41% whole-person functional impairment, excluding a permanent mental-health impairment rating and applying a multiplier to reduce the rating for Wooff’s distal clavicle excision. The district court affirmed except that it changed the whole-body calculation to 38%.

The Court’s Holding

The court affirmed the conclusion that section 85.34(2)(v) limits Wooff to functional-impairment benefits. The statute does not require that an employer’s offer of same-or-higher-paying work be “suitable” in light of the worker’s qualifications, training, or experience. Menefee offered Wooff a superintendent job paying more than his preinjury earnings and within his physical restrictions; Wooff’s subjective belief that he was unqualified did not avoid the statute’s consequence.

The court reversed on two impairment issues. It held that the commissioner improperly rejected psychiatrist Dr. Adam Woods’s mental-health impairment opinion: Woods used the fifth edition of the AMA Guides, and the record contained no reliable contrary evidence that Wooff’s symptoms were not permanent. The court also held that, under Koeller, the commissioner could not apply a multiplier to reduce the 10% upper-extremity rating for Wooff’s distal clavicle excision. It remanded for the commissioner to determine the functional impairment from Wooff’s mental-health injury and recalculate the award consistently with the opinion.

Key Takeaways

  • A same-or-higher-paying job offer triggers section 85.34(2)(v)’s functional-impairment limitation even if the worker contends the job is outside his qualifications.
  • Mental-health impairment may support functional-disability benefits when expert evidence applies the AMA Guides, despite the Guides’ lack of a numeric psychiatric rating.
  • The AMA Guides do not require a multiplier reducing the impairment rating for a distal clavicle excision.

Why It Matters

The decision applies Iowa’s post-2017 workers’ compensation framework according to its text: an employer’s qualifying wage offer, rather than an industrial-disability assessment, can control permanent-partial-disability benefits. At the same time, it requires the agency to evaluate supported mental-health impairment evidence and to follow the Iowa Supreme Court’s interpretation of the AMA Guides when calculating physical impairment.
